Abstract

Polyaniline films electrodeposited from acidified nonaqueous organic media were investigated for their electropolymerization behavior and charge-discharge characteristics. The solution system used for the electropolymerization of polyaniline film was CF₃COOH acidified propylene carbonate, which was previously found to be the best system for the preparation of a highly electroactive conducting polymer film. Electroactive polyaniline films only form in solutions where the mole ratio of acid (CF₃COOH) to aniline monomer is greater than one. As the acidity is increased, the resultant polyaniline film exhibits greater electroactivity and better charge-discharge performance of Li/polyaniline cathode cell. This effect may be ascribed to the high current efficiency in electro-oxidative polymerization and high redox reversibility of PAn films prepared in the high acid content solutions.
