Electrosynthesis of conducting polyanilines in biphasic media

Abstract

The electrochemical polymerization of aniline has been studied in the biphasic media. One phase comprises a polar medium containing some added electrolytes and the other a non-polar solvent containing the monomer. Ferric chloride has been used as the supporting electrolyte to catalyse the process of electropolymerization. Polyaniline was obtained in moderate yields with the highest Rp of 0·0237% per hour and a maximum polymerization efficiency of 61·65 ¢ 10-2 mol/Faraday. The observations and experimental results suggest a cationic mechanism. © 1988 the Indian Academy of Sciences.
