Abstract:
Achieving the desired standard of drinking water quality has been one of the concerns across water treatment plants in the developing countries. Processes such as grid chamber, coagulation, sedimentation, clarification, filtration, and disinfection are typically used in water purification plants. Among these methods, unit filtration which employs polymers is one of the new technologies. There have been many studies about the use of semiconductive TiO2with graphene oxide (GO) on the base of different polymeric membranes for the removal of azo dyes, especially methylene blue (MB). Polymeric GO-TiO2membranes have high photocatalytic, antifouling property and permeate the flux removal of organic pollutants. The aim of this study was to investigate the characteristics of different polymeric membranes such as anionic perfluorinated polymer (Nafion), cellulose acetate, polycarbonate (PC), polysulfone fluoride (PSF), and polyvinylidene fluoride (PVDF). The result of this study showed that the GO-TiO2membrane can be used in the field of water treatment and will be used for the removal of polycyclic aromatic hydrocarbons (PAHs) from wastewater.

Applications of polymeric materials in electrical engineering increasingly require improvements in operating voltages, performance, reliability, and size reduction. However, the resulting increase on the electric field in electrical systems can prevent achieving these goals. Polymer composites, functionalized with conductive or semiconductive particles, can allow us to reduce the electric field, thus grading the field within the system. In this paper, a comprehensive review of field-grading materials, their properties, and recent developments and applications is provided to realize high-performance high-voltage engineering applications.

Abstract:
Scanning tunneling microscopy (STM) becomes an excellent tool for surface structure studies in the case of conductive and semiconductive materials. The STM has advantage of extending the range of SEM and TEM studies to topography measurements in the angstrom scale. This method also does not require special sample preparations and can be used in air. The polymers with electronic conductivity are among compounds to be studied by STM. Recently the STM images of doped polypyrrole were obtained for polymer molecules deposited on graphite. The authors claimed the observation of single polypyrrole chains with helical structure and diameter approximately 1.2 nm. We had tried the electrochemical deposition of conductive polymers on ITO for preparing structured polypyrrole layers on a smooth conductive glass surface. These samples were studied by STM.The STM images of the surface of polypyrrole samples were obtained in air with the Nanoscope II).

Abstract:
Novel polysilanes, antimony-substituted polysilanes (APS) and iron-substituted polysilanes (IPS), were synthesized and characterized in this paper. To prepare these new metal-containing polymers, high reactive polymers, polymethylsilane (PMS) and polychloromethylsilane (PCMS) were used as mother polymers. The APS was synthesized directly by the reaction of PMS with SbCl3, while IPS was obtained from the reaction of PCMS with Na2Fe(CO)4 in the solvent of n-hexane. The polymers were characterized by elemental analysis, FT-IR, 1H-NMR, 29Si CP/MAS NMR, GPC, and UV. The number average molecular weights of these two polymers are between 1400 and 1600. These polymers show good semiconductive properties, whose intrinsic conductivities are in the range of 10-8~10-7S/cm, and can be increased to10-5S/cm after being doped with iodine.

The self-assembled solid crystal 2 has shown uniform conductance whereas 1 does not. The thermal stability of these crystals were determined by TGA analysis and found to be stable up to a higher temperature of 400°C. A temperature dependent current–voltage analysis were also performed and the results indicate that the conductivity of crystals 1 and 2increases with increase in temperature.

Abstract:
AbstractThe process of obtaining semiconductive and electrical conductive layers of copper sulfides by the sorption — diffusion method on polymers (polyamide 6 and low density polyethylene) using solutions of potassium pentathionate, K2S5O6, and higher polythionic acids, H2Sn O6 (n = 21, 33), was investigated. The layers were characterized for compositional and electrical properties by X-ray diffraction (XRD) analysis and sheet resistance measurements. The thickness of copper sulfides layers on polyamide and polyethylene increased with increasing time of polymer sulfurization and varied from 10 to 43 µm. The variations of the sheet resistance of copper sulfides layers formed on the surface of polymers on sulfurization agent used, the conditions of sulfurization, chemical and phase composition of the obtained layers were established. Sheet resistance of copper sulfides layers decreases with increasing time of the duration of sulfurization and the number of sulfur atoms in the polythionate anion. The sheet resistance values for copper sulfide layers formed on the polyamide surface are much lower than those of Cux S formed on the polyethylene surface. XRD showed the predomination of Cux S phases with low x values.

Abstract:
Carbon nitride materials require high temperatures (>500 °C) for their preparation, which entails substantial energy consumption. Furthermore, the high reaction temperature limits the materials’ processability and the control over their elemental composition. Therefore, alternative synthetic pathways that operate under milder conditions are still very much sought after. In this work, we prepared semiconductive carbon nitride (CN) polymers at low temperatures (300 °C) by carrying out the thermal condensation of triaminopyrimidine and acetoguanamine under a N2 atmosphere. These molecules are isomers: they display the same chemical formula but a different spatial distribution of their elements. X-ray photoelectron spectroscopy (XPS) experiments and electrochemical and photophysical characterization confirm that the initial spatial organization strongly determines the chemical composition and electronic structure of the materials, which, thanks to the preservation of functional groups in their surface, display excellent processability in liquid media.

Abstract:
Quartzite sculptures are considered some of the most impressive and informative archaeological remains which have been found in the most of Egyptian archaeological sites. Regrettably, quartzite sculptures suffer from many deterioration aspects such as granular disintegration, scaling, cracking, efflorescence, soiling, microbiological colonization. Water is the main aggressive deterioration factor of stones and stone-based monuments, as in addition to its direct role in deterioration mechanisms, it plays as a catalyst in the physicochemical and microbiological deterioration processes.During the last two decades, polymer nanocomposites have widely been applied in the field of cultural heritage conservation due to their unique physical and chemical characteristics. Zinc oxide nanoparticles are among the most important semiconductive nanomaterials that have been applied in the fabrication of nanocomposites. They have been demonstrated to improve the physicochemical and mechanical properties of polymers. In addition, zinc oxide nanoparticles were mixed with polymers in order to fabricate superhydrophobic and self-cleaning protective materials.The aim of this paper is to evaluate the efficiency of zinc oxide nanocomposites, in order to select the best of them for the consolidation and protection of a colossal quartzite statue of Ramesses II. The properties of the treated quartzite samples were comparatively examined by colourimetric measurements, static water contact angle, compressive strength, and scanning electron microscope.

Abstract:
Highly cross-linked polyethylene glycol monoliths (HCPEG) with interconnected micro and nanoporosity are produced via photo-crosslinking of low internal phase emulsions (LIPE). Unlike previous works, this approach allows the pre-processing functionalization of both polymer matrix and porosity by loading both phases of the emulsion template with several active fillers, such as enzymes, semiconductive polymers, and metallic nanostructures. Importantly, both polymer matrix and porosity of the resulting composite HCPEG monoliths show neither serious cross-contamination nor morphological alterations. All in all, this material behaves like a network of nano/micro flasks embedded into a permeable media. Mechanical and dielectric properties of these composites HCPEG monoliths can be tuned by varying the content of fillers. Since these composite materials are produced by photo-crosslinking of LIPEs, they can be easily and rapidly processed into complex shapes like microneedles arrays through replica molding without detrimental modifications of the porous morphology. In principle, the proposed strategy allows us to fabricate medical devices. As proof of concept, we embedded glucose oxidase enzyme in the nanoporosity and the resulting composite porous material retained the catalytic activity towards the oxidation of glucose.

Abstract:
The preparation of redox-active, ultrathin polymer films as the electrode materials represents a major challenge for miniaturized flexible electronics. Herein, we demonstrated a liquid–liquid interfacial polymerization approach to a coordination polymer films with ultrathin thickness from tri(terpyridine)-based building block and iron atoms. The as-synthesized polymer films exhibit flexible properties, good redox-active and narrow bandgap. After directly transferred to silicon wafers, the on-chip micro-supercapacitors of TpPB-Fe-MSC achieved the high specific capacitances of 1.25 mF cm−2 at 50 mV s−1 and volumetric energy density of 5.8 mWh cm−3, which are superior to most of semiconductive polymer-based micro-supercapacitor (MSC) devices. In addition, as-fabricated on-chip MSCs exhibit typical alternating current (AC) line-filtering performance (−71.3° at 120 Hz) and a short resistance–capacitance (RC) time (0.06 ms) with the electrolytes of PVA/LiCl. This study provides a simple interfacial approach to redox-active polymer films for microsized energy storage devices.

Abstract:
The properties and performance of electronic devices are crucially dependent on interface-related phenomena. The presence of interfaces can enable electronic device functionality (p-n diodes, solar cells); alternatively, non-functional interfaces can degrade device performance (ohmic vs. non-ohmic contacts). The most versatile tools for semiconductor interface characterization are ac (impedance spectroscopy, C-V) and dc (I-V) transport measurements. However, due to the lack of spatial resolution, these methods often cannot separate the contributions from electroactive interfaces and contacts. This is especially true for the non-traditional electronic materials such as semiconductive oxides, nitrides, conductive polymers, etc. Combined with the tendency towards miniaturization of electronic devices, this clearly necessitates spatially resolved ac and dc transport measurements.

Abstract:
Efficiency, current throughput, and speed of electronic devices are to a great extent dictated by charge carrier mobility. The classic approach to impart high carrier mobility to polymeric semiconductors has often relied on the assumption that extensive order and crystallinity are needed. Recently, however, this assumption has been challenged, because high mobility has been reported for semiconducting polymers that exhibit a surprisingly low degree of order. Here, we show that semiconducting polymers can be confined into weakly ordered fibers within an inert polymer matrix without affecting their charge transport properties. In these conditions, the semiconducting polymer chains are inhibited from attaining long-range order in the π-stacking or alkyl-stacking directions, as demonstrated from the absence of significant X-ray diffraction intensity corresponding to these crystallographic directions, yet still remain extended along the backbone direction and aggregate on a local length scale. As a result, the polymer films maintain high mobility even at very low concentrations. Our findings provide a simple picture that clarifies the role of local order and connectivity of domains.

Abstract:
Lamellar nanocomposites based on semiconducting polymers incorporated into layered inorganic matrices are prepared by the co-assembly of organic and inorganic precursors. Semiconducting polymer-incorporated silica is prepared by introducing the semiconducting polymers into a tetrahydrofuran (THF)/water homogeneous sol solution containing silica precursor species and a surface-active agent. Semiconducting polymer-incorporated MoS 2 and SnS 2 are prepared by Li intercalation into the inorganic compound, exfoliation and restack in the presence of the semiconducting polymer. All lamellar nanocomposite films are organized in domains aligned parallel to the substrate surface plane. The incorporated polymers maintain their semiconducting properties, as evident from their optical absorption and photoluminescence spectra. The optoelectronic properties of the nanocomposites depend on the properties of both the inorganic host and the incorporated guest polymer as demonstrated by integrating the nanocomposite films into light-emitting diodes. Devices based on polymer-incorporated silica and polymer-incorporated MoS 2 show no diode behaviour and no light emission due to the insulating and metallic properties of the silica and MoS 2 hosts. In contrast, diode performance and electroluminescence are obtained from devices based on semiconducting polymer-incorporated semiconducting SnS 2 , demonstrating that judicious selection of the composite components in combination with the optimization of material synthesis conditions allows new hierarchical structures to be tailored for electronic and optoelectronic applications.

Abstract:
Recent challenges in biomedical diagnostics show that the development of rapid affinity sensors is very important issue. Therefore, in this review we are aiming to outline the most important directions of affinity sensors where polymer-based semiconducting materials are applied. Progress in formation and development of such materials is overviewed and discussed. Some applicability aspects of conducting polymers in the design of affinity sensors are presented. The main attention is focused on bioanalytical application of conducting polymers such as polypyrrole, polyaniline, polythiophene and poly(3,4-ethylenedioxythiophene) ortho-phenylenediamine. In addition, some other polymers and inorganic materials that are suitable for molecular imprinting technology are also overviewed. Polymerization techniques, which are the most suitable for the development of composite structures suitable for affinity sensors are presented. Analytical signal transduction methods applied in affinity sensors based on polymer-based semiconducting materials are discussed. In this review the most attention is focused on the development and application of molecularly imprinted polymer-based structures, which can replace antibodies, receptors, and many others expensive affinity reagents. The applicability of electrochromic polymers in affinity sensor design is envisaged. Sufficient biocompatibility of some conducting polymers enables to apply them as “stealth coatings” in the future implantable affinity-sensors. Some new perspectives and trends in analytical application of polymer-based semiconducting materials are highlighted.

Abstract:
This paper reviews synthetic concepts for the functionalization of various inorganic nanoparticles with a shell consisting of organic polymers and possible applications of the resulting hybrid materials. A polymer coating can make inorganic nanoparticles soluble in many solvents as individual particles and not only do low molar mass solvents become suitable, but also polymers as a solid matrix. In the case of shape anisotropic particles (e.g., rods) a spontaneous self-organization (parallel orientation) of the nanoparticles can be achieved, because of the formation of lyotropic liquid crystalline phases. They offer the possibility to orient the shape of anisotropic nanoparticles macroscopically in external electric fields. At least, such hybrid materials allow semiconducting inorganic nanoparticles to be dispersed in functional polymer matrices, like films of semiconducting polymers. Thereby, the inorganic nanoparticles can be electrically connected and addressed by the polymer matrix. This allows LEDs to be prepared with highly fluorescent inorganic nanoparticles (quantum dots) as chromophores. Recent works have aimed to further improve these fascinating light emitting materials.

Abstract:
We focus on the published results of the interfaces between depositing metals and insulating and semiconducting polymers, and the interfaces between polymer films and metals. They indicated that when metal was deposited on polymer films, diffusion action occurred at the polymer surface and new interfacial states were formed during the process of deposition. Chemical reactions led to good adhesion and good performance of charge transfer between metal and polymer. When polymers were deposited on metal substrates, adsorption to the substrate occurred at the interface.

Abstract:
Polymers have been known for their flexibility and easy processing into coatings and films, which made them suitable to be applied in a variety of areas and in particular the growing area of organic electronics. The electronic properties of semiconducting polymers made them a serious rival in areas where until now inorganic materials were the most used, such as light emitting diodes or solar cells. Typical polymers can be seen as a network of molecular strands of varied lengths and orientations, with a random distribution of physical and chemical defects which makes them an anisotropic material. To further increase their performance, a better understanding of all aspects related to charge transport and space charge distribution in polymeric materials is required. The process associated with charge transport depends on the properties of the polymer molecules as well as connectivity and texture, and so we adopt a mesoscopic approach to build polymer structures. Changing the potential barrier for charge injection we can introduce holes in the polymer network and, by using a generalised Monte-Carlo method, we can simulate the transport of the injected charge through the polymer layer caused by imposing a voltage between two planar electrodes. Our results show that the way that holes distribute within polymer layer and charge localization in these materials is quite different from the inorganic ones.

Abstract:
In this work, fifteen polymers have been studied to test their potential as donors for polymer solar cells by density functional theory. Those polymers contained five homopolymers based on pyridazine, [1,2,thiadiazolo [3,4-pyridazine, [1,2,oxadiazole [3,4-pyridazine, isothiazolo [3,4-pyridazine and isoxazolo [3,4-pyridazine, and ten copolymers composed of the above compounds and thiophene incorporated with 1:1 and 1:2 ratios. The fifteen polymers have been examined in terms of the abilities of absorbing sunlight, stabilities in the environment, and photovoltaic properties. The results suggest that the copolymes DTHP, DTHTP, DTHOP, DTHITP, and DTHIXP are good material candidates of polymer donor for polymer solar cells.
