Electroactive Polyaniline Film Deposited from Non-Aqueous Media 2: Effect of Acid Concentration in Solutions

Abstract

Polyaniline films electro-deposited from acidified non-aqueous media were investigated for their electropolymerization behavior and charge-discharge characteristics. The solution system used for the electropolymerization of polyaniline films was CF3COOH acidified propylene carbonate, which was previously found to be the best system for the preparation of highly electroactive conducting polymer film. Electroactive polyaniline films only form in solutions wherein 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. Keywords: Polyaniline; Redox polymer; Nonaqueous electrolytes.
