“…The CP is created after encountering the monomer. This kind of method is called interfacial polymerization ( Figure 2 A), and it is used to receive CPHs in which the CP role is fulfilled with PANI [ 175 , 176 , 177 , 178 ], PPy [ 179 , 180 , 181 ] and rarely with PEDOT [ 182 , 183 , 184 , 185 , 186 ]. A modified interfacial polymerization method has been used to obtain PANI [ 187 ] and PPy [ 188 ].…”

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.

“…It has many excellent properties such as strength, water solubility, gas permeability and good thermal characteristics [12]. New electrically conducting and biocompatible nanocomposite hydrogel materials comprising of PANI nano-particles dispersed in PVA matrix were prepared by in situ polymerization of aniline [13]. These nanocomposites have several technological applications such as the removal of sulfate from waste water [14], very good FET characteristic on a transparent sheet and good mobility [15] and PANI/PVA membranes used in the pervaporation separation of water-isopropanol feed mixtures [16].…”

Polyaniline (PANI)/polyvinyl alcohol (PVA) nanocomposites has been prepared. Scanning electron microscopy, SEM of pure PVA and PANI/PVA nanocomposite films to monitor the morphology and dispersion of PANI on the surface of the PVA films. Positron annihilation lifetime measurements were carried out, in the air, at room temperature with a conventional fast-fast coincidence spectrometer. Dielectric permittivity e 0 , dielectric loss e 00 and AC conductivity r ac of PANI/PVA nanocomposites has been achieved in the range of frequencies 40 Hz-5 MHz and temperature range of 293-353 K. It was found that; O-ps lifetime, s 3 , its intensity, I 3 and relative fractional free volume, F r increase as the PANI content increases. The dielectric permitivity e 0 and loss e 00 increase with increasing the PANI content and decreases as the frequency increases. The values of the frequency exponent for the correlated barrier hopping s and the binding energy of the charge carriers W m for the investigated nanocomposites decrease with increasing PANI content. Finally, the dielectric permittivity e 0 was found to be directly proportional to the relative fractional free volume, F r .
