Abstract

Electrochemical copolymerization of diphenylamine (DPA) with anthranilic acid (AA) was performed in aqueous 4 M solution for different feed ratios of DPA using cyclic voltammetry. The copolymer film was grown for different numbers of cycles, and feed ratios of DPA. Electrochemical homopolymerization of DPA was also carried out under identical conditions and compared. A growth equation of the deposited films in terms of concentrations of DPA and AA and is deduced as by utilizing the charge associated for film deposition. The copolymer compositions were determined by X-ray photoelectron spectroscopy. Reactivity ratios of DPA and AA were computed by using Fineman-Ross and Kelen-Tüdös methods. © 2001 The Electrochemical Society. All rights reserved.
