Electrochemical Synthesis and Characterization of Conducting Copolymer: Poly(o-aniline-co-o-anisidine)

Abstract

Copolymerization of o-anisidine and o-anisidine was achieved electrochemically in aqueous solution containing H₂SO₄ as supporting electrolyte. The copolymer compositions can be altered by varying the monomer feed ratios during electrosynthesis. The films were electropolymerized in solution containing monomers in various ratio (0.025–0.1 M) and 1 M sulphuric acid as electrolyte by applying sequential linear potential scan rate 50 mV/s between − 0.2 to 1.0 V. versus Ag/AgCl electrode. The copolymers were characterized by cyclic voltammetric, conductivity measurement, UV-Visible spectroscopy, FT-IR spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and CHN elemental analysis.
