Copolymerization of o-anisidine and o-anisidine was achieved electrochemically in aqueous solution containing H 2 SO 4 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 À0.2 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.

A conducting composite of poly(o-anisidine), poly(o-toluidine) and poly(o-anisidine-co-o-toluidine) using incorporation of TiO 2 and SiO 2 was prepared by electrochemical polymerization. The films were electropolymerized in solution containing 0.1 M monomer(s), 1 M sulphuric acid as supporting electrolyte and 10 −5 M TiO 2 and SiO 2 by applying a sequential linear potential scan rate of 50 mV/s between −0.2 and 1.0 V versus an Ag/AgCl electrode. The characterization of the composites was done by cyclic voltametry, UV-Vis spectroscopy, electrical conductivity and thermogravimetric analysis. It is observed that the UV-Vis peaks appear in the region of the conducting emerladine salt (ES) phase. Overall, the polymers prepared using TiO 2 have higher conductivity than SiO 2 , with poly(o-toluidine)-TiO 2 conducting composite having the highest conductivivty. The composite does not lose its colour at higher temperature and, hence, can be utilized as conductive pigments required for anti-electrostatic applications.
