Abstract

Electrochemical copolymerization of diphenylamine (DPA) with anthranilic acid (AA) was performed in aqueous 4 M H₂SO₄ solution for different feed ratios of DPA using cyclic voltammetry. The copolymer film was grown for different numbers of cycles, C_n, 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 C_n is deduced as Q_G = k[DPA]^2.0[AA] ^0.2C^1.2_n 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.
