“…Ding et al reported polypyrrole films doped with Co(W 2 O 7 ) 6 10- and CuW 12 O 40 6- anions that exhibited an ESR signal attributable to a polymer−POM adduct. , Films of polypyrrole doped with molybdates were reported by Vernitskaya et al A composite film composed of H 2 W 12 O 40 6- anions and polypyrrole was prepared from the electrochemical polymerization of pyrrole in polytungstic acid solution. The composite film revealed proton permeability .…”

“…A lot of interest has been generated in the area of electrically conductive polymers with regards to the incorporation of POMs (primarily of the Keggin type) into the polymer matrix. − A rich literature exists on the immobilization of POMs by polymers such as polypyrrole, polythiophene, polyaniline, poly(1-naphthol), or poly( p -phenylene). Utilities of these doped materials have been proposed in the area of catalysis, due to the ease of separation of the POM catalyst from the reaction mixture when it is embedded in a polymer matrix.…”

“…Polypyrrole doped with POMs (ie., SiW 12 O 40 4- and P 2 W 18 O 62 6- ) via electrochemical polymerization exhibited redox properties inherent to the POMs and to the polypyrrole moiety. − The anions were retained in the polymer matrix without being ion-exchanged after repeated potential cycles in electrolyte solutions containing no POMs. Charge compensation on reduction was accomplished by cation insertion instead of anion release.…”

This review is focused on current state-of-the-art research on electroactive-based materials and their synthesis, as well as their physicochemical and biological properties. Special attention is paid to pristine intrinsically conducting polymers (ICPs) and their composites with other organic and inorganic components, well-defined micro- and nanostructures, and enhanced surface areas compared with those of conventionally prepared ICPs. Hydrogels, due to their defined porous structures and being filled with aqueous solution, offer the ability to increase the amount of immobilized chemical, biological or biochemical molecules. When other components are incorporated into ICPs, the materials form composites; in this particular case, they form conductive composites. The design and synthesis of conductive composites result in the inheritance of the advantages of each component and offer new features because of the synergistic effects between the components. The resulting structures of ICPs, conducting polymer hydrogels and their composites, as well as the unusual physicochemical properties, biocompatibility and multi-functionality of these materials, facilitate their bioapplications. The synergistic effects between constituents have made these materials particularly attractive as sensing elements for biological agents, and they also enable the immobilization of bioreceptors such as enzymes, antigen–antibodies, and nucleic acids onto their surfaces for the detection of an array of biological agents. Currently, these materials have unlimited applicability in biomedicine. In this review, we have limited discussion to three areas in which it seems that the use of ICPs and materials, including their different forms, are particularly interesting, namely, biosensors, delivery of drugs and tissue engineering.

“…3 ± 9, 11, 42, 43, 47, 48 a. The effect of the support material In the synthesis of electron-conducting polymers, different materials were used as the supports, viz., platinum, 49 ± 53 gold, 53 ± 55 metal oxides, 49,55,56 glassy carbon, 51,52 pyrographite, 53 stainless steel 49,57 and iron 58 ± 61 for polyaniline; noble metals, 62 conductive glass, 43,62 carbon materials, 11,63 aluminium, tantalum and copper, 62 ± 66 steels 63 ± 67 and semiconductors 68 for polypyrrole. From these studies, it can be concluded that the nature of the support material had virtually no effect on the synthesis and properties of conductive polymeric films with the thicknesses exceeding tens of monolayers.…”
