Autocatalytic Character of Anodic Polymerization of Aniline in Water-Organic Acid Solutions

A cyclic voltammetry study shows the anodic polymerization of aniline in 2 M HClO4 water–acetonitrile solutions to proceed via an EC: EC mechanism. In the chemical reaction, pernigraniline catalyzes the aniline oxidation, recovering from emeraldin in the second stage of the electrochemical process.
