Growth Behavial Couctive PolyanilineFilm on a Platinum Electrode by Electrochemical Oxidation (II)

전해산화에 의한 백금전극상 전도성 폴리아닐린 피막의 생장 거동(II)

The anodic oxidation of aniline in aqueous sulfuric acid solution on a platinum was studied. To examine of mechanism of this reaction, the date were obtained during controlled potential electrolysis, aided by computer system. The reaction mechanism was assumed the electrochemical-chemical-electrochemical(ECE) mechanism. We obtained the result that the intial charge transfer step proceeds through a radical cation, and this radical cation were bound cation led to may type of dimer in which p-aminodiphenylamine was de-electronated again to give the polymer.
