Abstract

Electrochemical copolymerization of diphenylamine (DPA) with aniline (ANI) has been carried out in aqueous sulfuric acid medium using a pulse potentiostic method (PPSM). The polymeric films were electrodeposited by employing different tunable parameters like pulse width (Pw), pulse number (Pn) etc., and the films deposited by PPSM were studied by cyclic voltammetry to identify their electrochemical characteristics and growth behavior. A growth equation for copolymer deposition relating the parameters of operation and charge associated for film deposition was obtained: Qa (mC/ms) = 1.05×10-7 [DPA][ANI]- 1/2 . The surface parameters of these films were evaluated. The copolymer was also characterized through Fourier transform infrared (FTIR) and ultraviolet (UV)-visible spectroscopic analysis. The cyclic voltammograms of the chemically synthesized and electrodeposited copolymer films were obtained.
