Abstract: Electropolymerization of aniline and 2,4-dinitrophenol on composite graphite electrode in phosphoric acid medium has been investigated by cyclic voltammetry. The copolymer has been synthesized in a mole ratio of 1:1 of aniline and 2,4-dinitrophenol in aqueous medium with para-toluene sulfonic acid and KCl as the binary supporting electrolytes. The properties of the modified electrodes have been characterized and compared with each other by FTIR spectroscopy. The inductive behavior of polyaniline and copolymers of aniline with 2,4-dinitrophenol has been identified via electrochemical impedance spectroscopy by determining parameters such as impedance and capacitance.
