Abstract:
The polystyrene-poly(arylene ether sulfone)-polystyrene (PS-PAES-PS) coil-semirod-coil triblock copolymer was synthesized by the condensation reaction of PS-COCl and H2N-PAES-NH2 telechelic polymers. The reaction was facile characterized by high yields with a perfect control over the block lengths. Following a known reaction protocol it was possible to selectively sulfonate the PS block of the triblock copolymer that led to the sulfonated copolymer sPS-PAES-sPS. Studies on its proton conductivity and methanol permeability were carried out to evaluate its use as the proton exchange membrane in direct methanol fuel cells. Proton conductivity of the membranes was increased depending on the sulfonic acid group content in the sulfonated polymer. The membranes exhibited good dimensional and thermal stability, and low methanol permeability compared to Nafion 117.

Abstract:
Among sustainable alternatives for replacing fossil-based chemicals, lignin is widely available on earth, albeit the least utilized component of biomass. In this work, lignin was polymerized with styrene in aqueous emulsion systems. The reaction afforded a yield of 20 wt % under the conditions of 100 g/L lignin concentration, pH 2.5, 0.35 mol/L sodium dodecyl sulfate concentration, 5 mol/mol styrene/lignin ratio, 5 wt % initiator, 90 °C, and 2 h. The lignin-g-styrene product under the selected conditions had a grafting degree of 31 mol % of styrene, which was determined by quantitative proton nuclear magnetic resonance (NMR). The solvent addition to the reaction mixture and deoxygenation did not improve the yield of the polymerization reaction. The produced lignin-g-styrene polymer was then sulfonated using concentrated sulfuric acid. By introducing sulfonate group on the lignin-g-styrene polymers, the solubility and anionic charge density of 92 wt % (in a 10 g/L solution) and −2.4 meq/g, respectively, were obtained. Fourier-transform infrared (FTIR), static light scattering, two-dimensional COSY NMR, elemental analyses, and differential scanning calorimetry (DSC) were also employed to characterize the properties of the lignin-g-styrene and sulfonate lignin-g-styrene products. Overall, sulfonated lignin-g-styrene polymer with a high anionicity and water solubility was produced.

4,4′-Dichlorodiphenylsulfone-3,3′-disulfonic acid (disodium) salt and 4,4′-difluorodiphenylsulfone were used as sulfonated monomer. 4,4′-Fluorophenyl sulfones were used as the nonsulfonated monomer. 4,4′-Dihydroxy diphenyl ether or 4,4′-thiodibenzenethiol was used as the comonomer. The sulfonated poly (aryl ether sulfone) (SPES) and sulfonated poly (arylene thioether sulfone) (SPTES) with sulfonation degree of 30% and 50% were successfully prepared by nucleophilic polycondensation. Two kinds of aromatic polymer proton exchange membranes were prepared by using sulfonated poly phthalazinone ether ketone (SPPEK) material and fluidization method. The performance of the prepared aromatic polymer proton exchange membrane was researched by the micromorphology, ion exchange capacity, water absorption and swelling rate, oxidation stability, tensile properties, and proton conductivity. Experimental results show that there is no agglomeration in the prepared aromatic polymer proton exchange membrane. The ion exchange capacity is 0.76–1.15 mmol/g. The water absorption and swelling rate increase with the increase of sulfonation degree. The sulfonated poly (aryl ether sulfone) membrane shows better oxidation stability than sulfonated poly (aryl sulfide sulfone). They have good mechanical stability. The prepared aromatic polymer proton exchange membrane with low sulfonation degree has good performance, which can be widely used in portable power equipment, electric vehicles, fixed power stations, and other new energy fields.

AbstractThe influence of density of amino groups, nanoparticles dimension and pH on the interaction between end-functionalized polymers and nanoparticles was extensively investigated in this study. PS–NH2 and H2N–PS–NH2 were prepared using reversible addition–fragmentation chain transfer polymerization and atom transfer radical polymerization. Zero-dimensional carbon dots with sulfonate groups, one-dimensional cellulose nanocrystals with sulfate groups and two-dimensional graphene with sulfonate groups in the aqueous phase were added into the toluene phase containing the aminated PS. The results indicate that aminated PS exhibited the strongest interfacial activity after compounding with sulfonated nanoparticles at a pH of 3. PS ended with two amino groups performed better in reducing the water/toluene interfacial tension than PS ended with only one amino group. The dimension of sulfonated nanoparticles also contributed significantly to the reduction in the water/toluene interfacial tension. The minimal interfacial tension was 4.49 mN/m after compounding PS–NH2 with sulfonated zero-dimensional carbon dots.

New sulfonated and non-sulfonated monomers — dinitro and diamino compounds — were prepared on the basis of 1,3,5-trinitrobenzene (TNB) which is the demethylation product of 2,4,6-trinitrotoluene (TNT). The sulfonated dinitrocompounds interacted with different binuclear bis-phenols under the conditions of aromatic nucleophilic nitrodisplacement reactions. Polyethers of moderate molecular weights were prepared on the basis of dinitrocompound containing electron-withdrawing 3,5-dinitrodiphenyl sulfone-4′-sulfonic acid “bridging” groups. Copolymers and blends with other sulfonated polymers were prepared to improve the film-forming properties of the polyethers developed on the basis of 3,5-dinitrodiphenyl sulfone-4′-sulfonic acid. High molecular weight sulfonated polynaphthylimides were prepared by the interaction of sulfonated diamine containing electron-donating ether group — 3,5-diaminodiphenyl ether-4′-sulfonic acid — with bis(naphthalic anhydride)s. The sulfonated polyethers and polynaphthylimides thus obtained contain sulfonic acid groups in the side chains.

Abstract:
Abstract Polymers and sulfonates are often part of the multicomponent chemical systems designed to increase oil recovery from depleted reservoirs. The objective of this work was to develop reliable, analytical methods for measuring polyacrylamide concentration in the presence of sulfonates. The need for new or improved methods arose because petroleum sulfonates caused interference with the standard turbidimetric method for determining polyacrylamides. This interference was eliminated by the addition of a butanol-extraction step to remove sulfonates. Based on the new manual procedure, an automated method was developed for use with a Technicon AutoAnalyzer™ to reduce analysis time. The automated method was designed with four modes of operation to cover high and low polymer concentrations with and without sulfonates present in the samples. Polymer concentrations ranging from 10 to a maximum of 1,200 wt ppm [10 to 1200 mg/kg] can be measured. A unique feature of the automated method is the continuous-flow solvent extraction. Depending on the mode, AutoAnalyzer throughput is 20 or 30 samples per hour. The accuracy of the results is 5% with extraction and 1% without extraction. Introduction Polyacrylamide polymers are used for mobility control and profile modification in EOR processes. Rapid and accurate analytical methods are needed for laboratory studies of polymer behavior and for the determination of polymer concentration in field samples. Procedures1,2 based on the turbidimetric reaction of polyacrylamide with bleach (sodium hypochlorite) are commonly used to measure the concentration of polyacrylamide in aqueous samples. In the attempt to apply these procedures to micellar solutions containing polymer, it was found that petroleum sulfonates cause interference because of both their inherent color and unknown reactions with bleach. Two different analytical methods were examined briefly. The starch-triiodide method developed by Scoggins and Miller3 also suffered from petroleum sulfonate interference. An automated method4 involving polymer hydrolysis followed by colorimetric determination of the liberated ammonia worked well with low concentrations of sulfonates. However, any free ammonia or ammonium ions in solution caused a substantial background response. For some of the emulsion-type polyacrylamides, the background response from ammonia in the product was much greater than the polymer response. Efforts to eliminate interferences were focused on the turbidimetric method because it was the easiest to use. Solvent extraction was selected as the best approach to remove petroleum sulfonates and oil from aqueous polymer samples. The requirements for a good solvent were that it remove the interfering components, separate rapidly from the aqueous phase, and have low water solubility. A series of alcohols and other solvents were tested; 1-butanol was found to be the most effective. Therefore, a butanol-extraction step was added to the standard turbidimetric method. Based on this new manual procedure, an automated method was developed for use with an AutoAnalyzer II (Technicon Industrial Systems). Both the manual and automated methods can be run with or without butanol extraction, depending on the type of samples. Manual Method In the turbidimetric method, polyacrylamide polymer reacts with sodium hypochlorite in acetic acid to form an insoluble chloroamide. The resulting turbidity is proportional to polymer concentration and can be measured with a spectrophotometer or turbidimeter. If petroleum sulfonates are present in the samples, they are extracted with 1-butanol that is acidified with HCl. The HCl is necessary to change the sulfonates into sulfonic acids, so that they can be extracted easily. To prevent excess HCl from interfering with the polyacrylamide reaction, the glacial acetic acid is buffered with sodium acetate.

Abstract:
Dans le cadre du développement de matériaux polymères conducteurs électroniques, ces travaux visent, d'une part, l'élaboration d'un modèle de la polymérisation de l'aniline par couplage chimique oxydant (en milieu acide et en présence de persulfate d'ammonium), et d'autre part, son extension à la copolymérisation de l'aniline avec des acides o-amino-phénoxyalcanesulfoniques. Mise en place pour l'étude de l'influence des conditions opératoires (nature de l'oxydant, acidité du milieu, concentrations des réactifs,), la technique de suivi de l'avancement de la réaction par la mesure du potentiel redox du milieu a permis de mettre en évidence les étapes essentielles du processus de polymérisation. Le modèle global proposé prend en compte une étape lente d'initiation (dimérisation), une phase de propagation (caractérisée par l'autocatalyse par le polymère formé) et la dégradation du dimère (hydrolyse). L’optimisation des paramètres cinétiques et la validation du modèle sont réalisées à partir des courbes d'évolution de la conversion d'aniline, déterminées à l'issu du dosage par CPG du monomère résiduel. L’étude cinétique des copolymérisations de l'aniline avec les dérivés substitués par un groupement alkoxysulfonique montre que la réactivité des comonomères en présence est très différente selon le processus envisagé. À cause de l'encombrement stérique des substituant, la dimérisation implique obligatoirement une molécule d'aniline. Au cours de la phase de propagation, l'effet électrodonneur des substituant, abaissant le potentiel d'oxydation par rapport à celui de l'aniline, est favorable à l'attaque électrophile des macromolécules, et entraine une réactivité des dérivés très supérieure à celle de l'aniline. Les copolymères obtenus présentent vraisemblablement une structure séquencée. Les conductivités de ces copolymères autodopés sont comprises entre 10-⁴ et 1 S. Cm-1.

Abstract:
Clean water is critical to the safety, security and survivability of humankind. Nearly 41% of the Earth's population lives in water-stressed areas, and water scarcity will be exacerbated by an increasing population. Over 96% of the total water is saline and only 0.8% is accessible fresh water. Thus, saltwater desalination has emerged as the key to tackle the problem of water scarcity. Our current work deals with the membrane process of reverse osmosis. Sulfonated polysulfones are a potential alternative to state-of-the-art thin film polyamides. Synthesized by step growth polymerization, polysulfone membranes have smooth surfaces and they are more chemically resistant relative to polyamides. Previously studied sulfonated polysulfone membranes were synthesized by direct copolymerization of pre-disulfonated comonomer and the sulfonate ions were placed on adjacent rings of bisphenol moiety. This study focuses on placing the sulfonate ions differently along the polysulfone backbone on isolated rings of hydroquinone moiety, and on adjacent rings of biphenol moiety- and its effect on the transport and hydrated mechanical properties of the membranes. Selective post sulfonation of poly(arylene ether sulfone) in mild conditions was also found to be an effective way to strategically place the sulfonate ions along the backbone of the polymer chain without the need to synthesize a new monomer. Hydroquinone based, amine terminated oligomers were synthesized with block molecular weights of 5000 and 10,000 g/mol. They were post-sulfonated and crosslinked at their termini with epoxy reagents. Such crosslinked and linear membranes had sulfonate ions on isolated rings of hydroquinone moiety. Synthesis and kinetics of controlled post-sulfonation of poly(arylene ether sulfones) that contained biphenol units were also reported. The sulfonation reaction proceeded only on the biphenol rings. The linear membranes had sulfonate ions on adjacent rings of biphenol moieties. The tensile measurements were performed on the membranes under fully hydrated conditions. All membranes remained glassy at values of water uptake. It was found that elastic moduli and yield strengths in the hydroquinone- based linear and crosslinked membranes increased with decrease in water uptakes in the membranes. The effect of plasticization of water superseded the effect of block length and degree of sulfonation in the membranes. The highest elastic modulus of 1420 MPa at lowest water uptake of 18% was observed in cross linked membrane with 50% repeat units being sulfonated (50% repeat units contain hydroquinone)and target molecular weight of 5000 g/mol. However, the hydroquinone membranes broke at low strains of < 20%. The hydrated mechanical properties could be improved by replacing the hydroquinone with biphenol moieties. The biphenol based post-sulfonated membrane showed high elastic modulus that was comparable to the hydroquinone-based counterparts at similar values of water uptake. The biphenol based membrane broke at higher strains of >80%. The post-sulfonated membranes- hydroquinone-based linear and crosslinked membranes and biphenol-based linear membranes had better transport properties than the previously studied sulfonated polysulfones that were synthesized by disulfonated comonomers.The post sulfonated hydroquinone-based membranes did not show a compromise in the rejection of monovalent ions in the presence of divalent ions in mixed feed water. The superior properties of the post-sulfonated membranes can potentially be attributed to the kinked backbone that potentially increased the free volume in the membranes and the sulfonate ions were spaced apart to potentially reduce their chelation with calcium (divalent) ions in mixed feed water. Interestingly, the biphenol based post-sulfonated membranes also did not have any compromise in the rejection of monovalent ions in the presence of divalent ions. This was potentially because the sulfonate ions were spaced far apart on the non-planar biphenol rings.

Abstract:
The electrical properties of sulfonated polyaniline (SPAN) and polyaniline (PANI) grown on both conventional (100) and high Miller index GaAs surfaces are investigated. These devices were electrically characterized using Current-Voltage (I-V), Capacitance-Voltage (C-V), Capacitance-Frequency (C-F), Capacitance-Conductance-Frequency (C-G-F), Deep Level Transient Spectroscopy (DLTS), and Laplace DLTS measurements in the temperature range 20 – 440 K. Electrically active defects are generated at/near the interface and away from the interface with energy levels deep in the bandgap of the materials. These defects considerably affect the electrical and optical properties of the devices. This thesis reports the effect of n-type GaAs substrate orientation, namely (100), (311)A and (311)B, on the electrical properties of sulfonated polyaniline (SPAN)/GaAs heterojunction devices. It was found that the interface state density (Dit) of SPAN/(311)B GaAs samples is lower than that of (100) and (311)A GaAs devices. This behaviour is attributed to the effect of crystallographic orientation of the substrates, and was confirmed by DLTS results as well. In addition, the inhomogeneity of the interface between various GaAs substrates and SPAN is investigated in terms of barrier height and ideality factor by performing I–V measurements at different temperatures (20–420 K). The I–V results indicate that the value of the rectification ratio (IF/IR) at 0.5 V is higher for SPAN/(311)B GaAs samples than for SPAN/(100) GaAs and SPAN/(311)A GaAs samples. Moreover, the barrier height decreases and the ideality factor increases with decreasing temperature for all three heterostructure devices. This thesis also reports an extensive study of the electrical properties of PANI/GaAs (organic-inorganic) hybrid heterojunctions. Polyaniline (PANI) thin films were deposited by a very simple technique on (100), (311)A and (311)B ntype Gallium Arsenide (GaAs) substrates to fabricate hybrid devices with excellent electrical properties. The DLTS and Laplace DLTS measurements illustrated that the number of defects at/very close to the interface region in PANI/(311)A GaAs samples is lower than those of PANI/(100) GaAs and PANI/(311)B GaAs samples. Moreover, the analysis of I–V characteristics based on the thermionic emission mechanism has shown a decrease of the barrier height and an increase of the ideality factor at lower temperatures for all the three hybrid devices. The interface states were analysed by series resistance obtained using the C–G–V methods. The interface state density (Dit) of PANI/(100) GaAs devices is approximately one and two order of magnitude higher than that of PANI/(311)B GaAs and PANI/(311)A GaAs devices, respectively. Additionally, the devices show excellent air stability, with rectification ratio values almost unaltered after two years of storage under ambient conditions, making the polyaniline an interesting conductor polymer for future devices applications.

Abstract:
A majority of research on ionic polymer transducers has used Nafion™ as the base material. Varying the physical and chemical properties of Nafion is difficult, which limits the understanding and development of ionic transducers. In this study we investigate a novel class of polymers called BPSH (sulfonated poly(arylene ether sulfone)s). The polymers are synthesized by the direct polymerization of sulfonated monomers. This synthetic scheme affords precise control of the amount and the location of ionic groups along the polymar backbone. These polymers differ from Nafion™ in two major ways. First, the concentration of ionic groups on a mass basis is almost double that of standard Nafion™, 1.51 meq/g for BPSH-30 versus 0.91 meq/g for Nafion™ 1100. Also, the backbone of the BPSH copolymers is much stiffer than Nafion, which affords a higher modulus material. Both of these factors, ion content and modulus, are expected to affect the performance of polymer-based actuators. Another ionomer characterized is the PATS (poly(arylene thiother sulfone)s) which is similar to BPSH. For both polymers we are varying the ionic concentration, stiffness, and water content. Those variations are fostering the understanding of operating concepts of ionic transducers, especially the correlation between ionic transducers, especially the correlation between ionic concentration and performance. Experiments on BPSH-35 demonstrate improved performance as compared to Nafion™ They provide larger strain per unit volt, larger force generated, and larger bandwidth. The novel polymers are characterized as sensors and actuators.

Abstract:
Shape memory polymers (SMPs) are a widely studied class of materials due to their numerous applications in various fields of engineering. They find applications in deployable structures, biomedical devices, adaptive optical devices, sensors and actuators, in textiles etc. Recent studies have shown shape memory behavior in many polymers. Sulfonated poly ether ether ketone (SPEEK) is an ionic polymer which is being extensively studied for its application in fuel cells as a Proton Exchange Membrane (PEM) polymer due to its relatively higher thermal and mechanical stability over other PEMs in addition to proton transport. Recent studies on a sulfonated ionomer, Nafion® which has only one broad reversible phase transition, can show tunable, multiple shape memory effects by deforming the polymer at different temperatures without compromising the shape fixity (Rf). This paper reports, for the first time, the swelling (in solvents) induced shape memory behavior observed in SPEEK. The study was motivated by the preliminary observations of the response of SPEEK to solvent stimulus. SPEEK samples of varying degrees of sulfonation (DS) were prepared by the sulfonation of poly ether ether ketone (PEEK). The shape fixation and recovery rates (Rr) of the polymer under different temperatures and solvent conditions are reported. A comparative study of the shape memory response of the material with varying DS was also carried out. We also report for the first time the potential use of the parallel plate geometry of a rheometer for estimating the force during the shape recovery process. Visual demonstration of the shape memory effect is carried out using solvents at different temperatures.

Abstract:
Abstract Carbonate reservoirs are challenging for chemical EOR, particularly in selecting fine-tuned chemical formulations which combine high performance, stable behavior, and trouble-free operations. The design of suitable formulations requires substantial laboratory work and a solid methodology. In this paper, a systematic all-inclusive laboratory workflow to design a surfactant-polymer (SP) formulation for a carbonate reservoir is presented. In this work, a complete process for development and evaluation of an SP formulation for high-salinity high-temperature conditions is proposed and adopted. For which, a high throughput robotic platform is used for efficient and robust formulation design. The process is illustrated on an actual case with harsh reservoir conditions (i.e. a high temperature of 100℃ and high connate salinity of 213,000 mg/L). The SP design methodology consisted of five steps: surfactant design, polymer selection, surfactant/polymer verification, topside assessment, and oil-displacement evaluation. The surfactant formulation design consisted of four substeps: solubility scans, phase-behavior scans (salinity scans), IFT measurements, and static adsorption tests. The sourced polymers were screened based on three key performance indicators: viscosity, filter ratio, and thermal stability. The selected surfactant formulations and polymers were then assessed as sloppy slugs in terms of compatibility and injectivity. Then, the unique topside assessment was conducted where it consisted of two components focusing on: separation kinetics and separated water quality. Finally, an oil displacement study was performed using a preserved composite plug, in which the SP formulation developed through the outlined process was used. The results demonstrate the potential of a mixture of Olefin Sulfonate (OS) and Alkyl Glyceryl Ether Sulfonate (AGES). The results also illustrate couple of polymers with stabilities suitable for high temperature conditions: an associative polymer, and an AM/AMPS copolymer. In addition, injectivity corefloods supported the SP slug transportability across the porous media. Corefloods also demonstrated the SP slug capacity to recover around 62% ROIC (remaining oil in core). Finally, SP in produced brines improved the separation kinetics but lead to a slight deterioration in separated water quality. A key novelty of the adopted workflow is the integration of topside assessment. In addition, the experimental steps were clearly delineated including the preparation of representative oils. Beside a clear layout of the methodology, the work demonstrates that a surfactant-polymer formulation can successfully be designed for high temperature carbonate reservoirs and provide encouraging guidelines with respect to SP impact on topside facilities.

Abstract:
Abstract Polymer transport and retention affect oil recovery and economic feasibility of EOR processes. Most studies on polymer transport have focused on sandstones with permeabilities (k) higher than 200 mD. A limited number of studies were conducted in carbonates with k less than 100 mD and very few in the presence of residual oil. In this work, transport of four polymers with different molecular weights (MW) and functional groups are studied in Edwards Yellow outcrop cores (k&lt;50 mD) with and without residual oil saturation (Sor). The retention of polymers was estimated by both the material balance method and the double-bank method. The polymer concentration was measured by both the total organic carbon (TOC) analyzer and the capillary tube rheology. Partially hydrolyzed acrylamide (HPAM) polymers exhibited high retention (&gt; 150 μg/g), inaccessible pore volume (IPV) greater than 7%, and high residual resistance factor (&gt;9). A sulfonated polyacrylamide (AN132), showed low retentions (&lt; 20 μg/g) and low IPV. The residual resistance factor (RRF) of AN132 in the water-saturated rock was less than 2, indicating little blocking of pore throats in these tight rocks. The retention and RRF of the AN132 polymer increased in the presence of residual oil saturation due to partial blocking of the smaller pore throats available for polymer propagation in an oil-wet core.

Abstract:
Magnesium-aluminum (Mg-Al) based layered double hydroxide (LDH) polymer nanocomposites were developed through the implementation of a rehydration technique. Organic anionic surfactant sodium dodecyl sulfate (SDS) and an anionic polymer, poly(styrene sulfonate) (PSS) were used for intercalation in the cationic intergallery spacing of LDH. This rehydration technique was performed by calcination of the LDH precursor for removal of carbonate anion followed by rehydration of organic anionic phase in a nitrogen rich atmosphere. The resulting nanocomposites were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and powder x-ray diffraction (XRD).
