Abstract

Electrodeposited films of polyaniline (PANI) and poly(2-amino diphenylamine-co-aniline) were generated by cyclic voltammetry. PANI and copolymer films were subjected to electrochemical impedance spectroscopy (EIS) at different applied potentials. An inductive behavior was noticed at 0.50 V. The presence of hydrolysis product has definite role in generating the inductive behavior. Inductive behavior was adequately explained through the equivalent circuit consisting of an inductor element (L). PANI and copolymer films were also subjected to impedance analysis in HCl and H₂SO₄ media to investigate the influence of anion on the inductive behavior. The inductive behavior was found to be predominant for PANI than for copolymer. For both polymers, sulphate ion influences L significantly than chloride ion.
