Abstract

A deep yellow polyaniline was formed at the anodic electrode during electrochemical oxidation of aniline in the alkaline solution.The peak of oxidation potential for aniline in the alkaline solution was 0. 7 V (vs.Ag/AgCl with a saturated KCl solution),which is about 0. 3V less than that in the acidic solution.The results from rotating ring-disk electrode experiment show that two soluble intermediates were generated during electrochemical oxidation of aniline.The colour of the polymer in the alkaline solution is independent of applied potential and pH values.An adsorption peak was observed in the UV region at 500 nm for the polymer.The polymer has a high stability in air and the alkaline solution.
