Effects of Cresol-Sulfonic Acid on Redox Behavior of Polyaniline

Polyaniline was possibly doped with cresol-sulfonic acid, though it failed to electrodeposit the polymer from solutions of aniline in cresol-sulfonic acid. The presence of cresol-sulfonate anions changed the redox peaks of the polymer in thier positions and heights. Catalytic oxidation of cresol-sulfonic acid was observed on polyaniline-filmed electrodes at potentials of a limited interval.
