Abstract:
New gel polymer electrolytes containing poly(vinylidene chloride-co-acrylonitrile) and poly(methyl methacrylate) are prepared by solution casting method. With the addition of 60 wt.% of EC to PVdC-AN/PMMA blend, ionic conductivity value0.398×10-6 S cm−1has been achieved. XRD and FT-IR studies have been conducted to investigate the structure and complexation in the polymer gel electrolytes. The FT-IR spectra show that the functional groups C=O and C≡N play major role in ion conduction. Thermal stability of the prepared membranes is found to be about 180°C.

Abstract:
Flexible free standing polymer electrolyte films have been successfully prepared using a blend of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinyl chloride) (PVC) doped with lithium perchlorate (LiClO4). The conductivity of the film was influenced by salt concentration and the degree of crystallinity. An optimum room temperature conductivity obtained was 2.10 x 10-4S cm-1for PVDF-HFP/PVC containing 35 wt.% LiClO4. The temperature-dependent conductivity of the polymer films exhibited VTF-type behaviour.

Abstract:
The effect of high-dose irradiation on the migration of dioctyl adipate (DOA) and acetyl tributyl citrate (ATBC) plasticizers from food-grade poly(vinyl chloride) (PVC) and poly(vinylidene chloride/vinyl chloride) (PVDC/PVC) copolymer (Saran) films, respectively, into olive oil was studied. The results showed a significantly higher amount of DOA migrated into olive oil from irradiated versus nonirradiated samples. This difference was more noticeable in oil samples collected during initial periods of contad. The amount of DOA migrating into olive oil was lower for samples irradiated at a dose of 20 kGy in comparison with samples irradiated at adose of 50 kGy. At a sampling time of 1 h the amount of DOA that migrated into olive oil was 93.9 mg/liter, 141.5 mg/liter, and 183.4 mg/liter for nonirradiated samples, 20-kGy irradiated samples, and 50-kGy irradiated samples, respectively. After 288 hr (12 days) of oil-film contad the respective amounts were 390.8 mg/liter, 409.2 mg/liter, and 430.1 mg/liter. There were no statistically significad differences in migrating amount of ATBC between nonirradiated samples and samples irradiated at a dose of 20 kGy, while in samples irradiated at a dose of 50 kGy the migration of ATBC was increased. After 1 h of oil-film contad no detectable amounts of ATBC had migrated. After 288 h of contad the amounts of ATBC that migrated into olive oil were 3.59 mg/liter, 3.56 mg/liter, and 4.12 mg/liter for nonirradiated samples, 20-kGy irradiated samples, and 50-kGy irradiated samples, respectively. It is suggested that plasticized PVC should not be used in direct contact with high-fat foodstuffs with or without irradiation treatment.

Abstract:
Polymer electrolytes with poly(vinyl chloride) (PVC) and poly(vinylidene fluoride)(PVdF) blend as matrix and lithium perchlorate (LiClO4) as dopant salt were prepared by solvent casting technique. Propylene carbonate was used as plasticizer and tetrahydrofuran (THF) as common solvent. Zinc oxide nano particles were synthesized through novel solid-state milling method and incorporated as filler. The content (wt%) of nano filler in the polymer electrolyte was systematically varied to study its influence on the conductivity of the electrolyte membranes. The films were subjected to complex impedance analysis in the frequency range 50 – 100 KHz. The analysis reveals the strong influence of filler particles on the conductivity profile of the electrolytes.

Abstract:
Probiotic products are becoming more common in everyday use around the world, while at the same time, the interest of scientists in researching probiotic production and use is increasing. Stability of a probiotic product in pharmaceutical production is affected by the choice of probiotic strain, formulation, and packaging. Packaging is the final stage of production and presents a crucial factor for the stability of probiotic products to maintain declared probiotic viability during the products' shelf life. The present research describes the influence of additional packaging material on the encapsulated probiotic product, which contains Lactiplantibacillus plantarum 299v. In specific, the effect of additional blister protection within flow pack bags was investigated. Blisters were made of a chloride/poly-vinylidene chloride/polyethylene-triplex foil (PVC/PVdC/PE foil) and aluminum foil. Viability of probiotic lactobacilli cells protected in blisters only was compared to those packed in flow pack bags filled with nitrogen as an inert gas. Better protection of probiotic cells from oxygen, light, and moisture was determined in the capsules in the latter case. In specific, introduction of additional blister protection in flow pack bags resulted in ~11 % higher probiotic viability when compared to the other blister samples without such protection after 24 months, and therefore it enabled more efficient storage of the product during use.

Abstract:
 AbstractPolymer blend of poly (vinyl chloride) and poly(vinylidene fluoride) of nominal composition (30PVC/70PVDF) wt:wt were prepared in the form of thin films using casting technique. Samples of the same composition doped with gradient concentration of nano lithium salt (LTO) were prepared and studied. Proposed filler was characterized using Fourier transform infrared spectroscopy (FTIR), UV/vis. optical absorption, X-ray diffraction (XRD), Transmission electron microscopy (TEM) and Electron diffraction (ED). Obtained data approve the crystalline nano structure of filler with a cubic structure of average size (25-30 nm). Prepared nano composites were then investigated using different spectroscopic methods. XRD reveals the amorphous nature of the base polymer blend with tendency for increase in crystallinity with increasing the content of lithium salt. FTIR shows a preservation of the main vibrational spectral bands in their position with small variation in the area and intensity of some spectral bands related to the interaction between polymer and filler.

Abstract:
Poly(vinylidene fluoride)(PVDF), poly(vinyl chloride)(PVC), and poly(methyl methacrylate)(PMMA) were used as the main materials in the preparation of novel blend five-hole membrane. Dimethylacetamide (DMAC) and polyvinyl pyrrolidone (PVP) were used as solvent and additive, respectively. The effect of some external coagulation conditions on the property of five-hole membrane was studied. The external coagulation conditions investigated in the work were the coagulation temperature and the DMAC content in coagulation bath. The result showed that the flux increased along with the increase of coagulation bath temperature and could reach the max at 35°C, then decreased gradually. The effect of the DMAC content in coagulation bath on flux is very similar to that of the temperature. The cross-sectional structures were examined by scanning electron microscopy.

Abstract:
The combination of properties of intrinsically conducting polymers (ICPs) and functional nanostructured template materials opens up prospects for their use in various fields, ranging from bioelectronics to sensors and energy conversion. Successful combinations solve one of the important drawbacks of many ICPs, created by their insolubility and infusibility, and help to achieve their full potential in thermally processable materials. When developing such hybrid materials, it is necessary to take into account the sensitivity of ICP properties to interphase interactions due to extended π-conjugation in these polymers. However, this aspect of ICP-based nanocomposites has not been sufficiently studied yet. In this paper we investigate the effect of template submicron poly(vinylidene fluoride) (PVDF) particles and the nature of the dopant on properties of poly(3-methylthiophene) (P3MT) precipitated as the shell at the PVDF core surface in the course of the 3MT oxidative polymerization. For this purpose, we compare the properties of P3MT phase of the composites with the properties of the neat P3MT doped with dodecylbenzenesulfonate (DBS), perfluorooctanoate (PFO) and chloride anions. In the formed composite core-shell particles the P3MT is in the form of asymmetric nanoparticles which are localized almost exclusively at the surface of PVDF particles. According to the conjugation length, neat polymers form the following series: P3MT-Cl > P3MT-DBS > P3MT-PFO as evidenced by the IR spectral analysis. In their composites the conjugation length of P3MT doped with Cl- does not change noticeably, while for the DBS and PFO anions cases it increases and for the DBS case it exceeds that of Cl- case. X-ray phase analysis showed an increase in the degree of crystallinity of P3MT-Cl and P3MT-DBS phases in the composition of composites by 1.4 and 1.3 times relative to the corresponding values for the neat doped P3MTs. Such an increase can be caused by the influence of the local electric field of the dipoles of the electroactive part of the crystalline phase of PVDF (β- and γ-phase) on the spatial arrangement of charged P3MT macromolecules formed on the surface of PVDF. Thermogravimetric studies show an increase in the thermal stability of the doped P3MT phase of nanocomposites while conductivity measurements reveal a significant effect of the nature of the dopant anion.

Abstract:
A supercritical CO2 drying process was used to prepare an innovative nanocomposite, formed by a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF HFP) aerogel loaded with RuO2 nanoparticles. The produced nanocomposites, at 10% and 60% w/w of RuO2, were tested for the electrochemical oxidation of model tannery wastewaters. The effect of the electrochemical oxidation parameters, like pH, temperature, and current density, on tannic acid, intermediates, and chemical oxygen demand (COD) removal, was investigated. In particular, the electrolysis of a simulated real tannery wastewater, using PVDF HFP_RuO2 60, was optimized working at pH 10, 40 °C, and setting the current density at 600 A/m2. Operating in this way, surfactants, sulfides, and tannins oxidation was achieved in about 2.5 h, ammonium nitrogen oxidation in 3 h, and COD removal in 5 h. When chloride-containing solutions were tested, the purification was due to indirect electrolysis, related to surface redox reactions generating active chlorine. Moreover, sulfide ions were converted into sulfates and ammonium nitrogen in gaseous N2.

An original way for recycling PET / PVDC films is proposed by their chemical transformation with titanium alkoxydes by reactive extrusion process in the solid state. The exchange reactions between these organo-metallic species and the PET were carried out at temperatures between 250 and 280°C at laboratory scale and they have allowed to shorten the PET's chains, in short oligomers with low melting temperatures, in a range of reaction time of few minutes. These oligomers could be post-functionalized with diols. The technologic transfert of these exchange reactions to the twin screw extruder scale was optimized in order to transform PET / PVDC films at temperatures between 130 and 180°c without degrading the PVDC. The titanium alkoxydes allow to stabilize the release of hydrochloric acid (HCl) during thermal degradation of this halogenated polymer. The reuse of these oligomers into different polyurethane systems were then studied and demonstrated the compatibility of PET oligomers with these matrix with improvements of some physical and mechanical properties

Abstract:
Les copolymères de PVDC possèdent des propriétés barrières à l'oxygène et à la vapeur d'eau qui en font un matériau de choix pour l'industrie de l'emballage alimentaire ou pharmaceutique. Les latex à base de PVDC (noté latex de PVDC) sont actuellement stabilisés par des tensioactifs de faibles masses molaires susceptibles de migrer dans le film après enduction et de dégrader ses propriétés. Le but de ce projet est donc la synthèse de latex de PVDC sans tensioactif en présence d'agents RAFT macromoléculaires (macroRAFT) hydrophiles qui jouent le rôle de stabilisants des particules tout en étant liés de manière covalente à celles-ci. La copolymérisation par RAFT du VDC a tout d'abord été étudié en milieu homogène. Des copolymères statistiques et des copolymères à blocs amphiphiles à base de VDC bien définis ont été synthétisés. Ensuite, des macroRAFT hydrophiles non ioniques et sensibles au pH, préformés en milieu organique, ont montré la possibilité d'obtenir des latex de PVDC où le bloc hydrophile stabilisant était lié de manière covalente aux particules. Enfin, un procédé intégralement dans l'eau a été mis au point avec des macroRAFT sensibles au pH ou chargés de manière permanente, synthétisés en milieu aqueux et utilisés directement dans la polymérisation en émulsion. Des latex stables de PVDC ont été obtenus à des taux de solide de 40 % à partir de faibles quantités de macroRAFT répondant ainsi aux exigences industrielles du projet. Les films formés à partir de ces latex auto-stabilisés sont transparents, ne blanchissent que très peu lors du contact avec l'eau, contrairement au film commercial de référence et ont montré des propriétés barrières supérieures
Since poly(vinylidene chloride) (PVDC)-based copolymers present unique oxygen and water vapor barrier properties, they are a material of choice for pharmaceutical blisters and food packaging. PVDC-based latexes used in coating applications are generally stabilized by low molecular weight surfactants, which are prone to migration in the film after coating and cause material degradation. The main goal of our project is the synthesis of surfactant-free PVDC-based latexes by using hydrophilic macromolecular RAFT agents (macroRAFT). The latter plays the role of precursor of stabilizer and limits migration phenomena by being covalently bound to particles. In a first part, RAFT polymerization of VDC was studied in homogenous solution. Well-defined statistical and amphiphilic blocks copolymers based on PVDC were synthesized. Then, PVDC-based latexes were obtained by emulsion polymerization mediated by hydrophilic non-ionic and pH sensitive macroRAFT pre-formed in organic solvent. Those hydrophilic segments were chemically anchored to the particles. A fully water-based process was developed by synthesizing in water pH sensitive and permanently charged hydrophilic macroRAFT which were further used directly in emulsion polymerization without additional purification. Stable PVDC-based latexes exhibiting solids content of 40 % were obtained using a very small quantity of macroRAFT, fulfilling the industrial requirements. Drying of self-stabilized latexes led to transparent films which display only a slight whitening after water exposition contrary to the commercial film reference and better barrier properties

Poly (vinylidene chloride-co-vinyl chloride, PVDCB)/clay nanocomposites were prepared by melt blending of the polymer with a fluorinated synthetic mica (MEE), in the presence of dioctyl phthalate (DOP) which acted as a plasticizer. The nanostructure of the PVDCB/MEE nanocomposites was characterized by a wide angle X-ray diffractometer (WAXD) and a transmission electron microscope (TEM). It was found that both intercalated and exfoliated structures were present in the PVDCB/MEE nanocomposities. Below 8 wt% MEE, the intercalation effect of PVDCB/MEE nanocomposites decreased with MEE. The thermal stability of PVDCB/MEE nanocomposites was evaluated by a thermogravimetric analyzer (TGA). Results showed that, in nitrogen, PVDCB/MEE nanocomposites demonstrated a one-step thermal degradation behavior, and its thermal stability was significantly related to the morphology of nanocomposites, the DOP content and the degraded PVDC structure. In Air, PVDCB/MEE nanocomposites presented a two-step thermal degradation behavior. The flammability of PVDCB/MEE nanocomposites reduced as the amount of MEE increased. Below 5 wt% MEE, the glass transition temperature (Tg) of PVDCB/MEE nanocomposites increased with MEE. The crystallization temperature (Tc) of PVDCB showed a higher value in PVDCB/MEE nanocomposites and it can be related to the presence of DOP. Water vapor /oxygen barrier properties of PVDCB/MEE nanocomposites were evaluated by water vapor permeability tester and gas permeability tester, respectively. Results showed that water vapor /oxygen barrier properties were significantly improved in PVDCB/MEE nanocomposites and they can be related to the morphology of nanocomposites, the DOP content and the crystallinity of PVDCB.

Abstract:
The work is devoted to the development and study of conducting nanocomposites of poly(3-methylthiophene) (P3MT) and poly(vinylidene fluoride) (PVDF), suitable for changing properties when interaction with of the environment components, and to find factors of influence on properties of such materials. The kinetic aspects of P3MT formation in the process of 3-methylthiophene (3MT) polymerization in PVDF dispersions in the presence of dopants of different nature, in particular, chloride (Cl-), as well as surface-active dodecylbenzenesulfonate (DBS-) and perfluorooctanoate (PFO-) anions are studied. It is found that DBS- and PFO- anions inhibit 3MT oxidation and decrease P3MT yield in comparison with those of chloride anions. It is shown that P3MT is formed through two consecutive kinetically different reactions of pseudo-first order in terms of the oxidant concentration. Transmission electron microscopy revealed that as a result of such polymerization nanoparticles of doped P3MT formed a surface inhomogeneous layer on PVDF particles, thus forming nanocomposite particles with core-shell morphology. Thermal studies showed higher thermal stability of the doped P3MT phase in the nanocomposite compared to the pure polymer. It is found that thermal stability of the P3MT phase in the PVDF/P3MT-DBS nanocomposites is higher than in the PVDF/P3MT-Cl. The influence of the dopant nature and content of doped P3MT on conductivity and sensitivity of the nanocomposites to vapors of harmful volatile organic compounds (acetone and isopropanol) is characterized. The strongest responses to acetone are shown by the nanocomposite with PFO- dopant. In the DBS- dopant case medium intensity responses are found and the lowest ones are observed for Cl- dopant. It is shown that the sensitivity of nanocomposites extremely depends on the conducting polymer content.
