摘要：

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. © 1990, The Electrochemical Society, Inc.
