Electrical investigation on thiophene–indole conducting copolymers as-synthesized through in situ chemical copolymerization route

摘要: In this communication, a series of thiophene–indole conducting copolymers are successfully synthesized via in situ chemical oxidative copolymerization thiophene and indole monomers using anhydrous FeCl3 as an oxidant. Fourier-transform infrared spectroscopy studies depict the structural confirmation. X-ray diffraction profile indicates amorphous nature as-synthesized copolymeric samples. The electrical conductivity, dielectric properties relaxation model indeed studied AC impedance technique frequency temperature ranges 20 Hz–1 MHz 303–393 K, respectively. dependence conductivity as-prepared samples followed Arrhenius relation. variation with obeys Jonscher’s power law. electric modulus spectra showed non-Debye materials.
