This work aimed to produce poly(acrylonitrile-co-itaconic acid) (P(AN-co-IA)) nanocomposites with poly(3,4ethylenedioxythiophene) (PEDOT) and poly(3-methoxythiophene) (PMOT). An anionic surfactant sodium dodecyl benzene sulphonate was used in emulsion polymerization for nanocomposite production. Incorporations of PEDOT and PMOT on the nanoparticles were characterized by scanning electron microscopy (SEM), atomic force microscopy, Fourier transform infrared-attenuated total reflectance spectroscopy and ultraviolet spectroscopy. These nanoparticles were blended with PAN and the blends were electrospun to produce P(AN-co-IA)-polythiophene-derivative-based nanofibres, and the obtained nanofibres were characterized by SEM and energy dispersive spectroscopy. In addition, electrochemical impedance studies conducted on nanofibres showed that PEDOT and PMOT in matrix polymer P(AN-co-IA) exhibited capacitive behaviour comparable to that of ITO-PET. Their capacitive behaviour changed with the amount of electroactive polymer.

Poly(acrylonitrile-co-butyl acrylate) [P(AN-co-BuA)] was synthesized from acrylonitrile (AN) 95% and butyl acrylate (BuA) 5%-molar ratios-by free-radical polymerization in aqueous media, using ceric ammonium nitrate as an initiator. Pyrrole was oxidatively polymerized in dimethylformamide in the presence of P(AN-co-BuA) matrix to produce polypyrrole (PPy) composites. Composite thin films were produced by solution casting onto smooth glass surfaces. Scanning electron microscopy and Fourier transform infrared-attenuated total reflectance analysis of thin films revealed the presence of PPy in the composite structure. Electrical impedance measurements were conducted to reveal the electrical conductivity change due to increasing PPy content. Enhancing the flexibility of PPy structures, as a composite film composed of PPy, could find substantial utility in the application of PPy products. BuA in a copolymer structure with AN improved the mechanical properties of the resulting copolymer by compensating the mechanical disadvantages of PPy. The
