Abstract

For the first time, poly(o-toludine-co-metanilic acid) (POM) layers have been deposited on mild steel (MS) substrate by galvanostatic (GS), potentiostatic (PS) and potentiodynamic (PD) methods. AC impedance of the electrodes has been analyzed. The shape and impedance parameters of galvanostatically prepared electrodes are similar to those of potentiostatically grown electrodes. The impedance spectra of potentiodynamically prepared electrode, however, are different. The redox behavior of POM copolymer has been studied using cyclicvoltammetric technique. Also, the copolymer prepared by potentiodynamic method has been characterized by UV–vis spectroscopy, Fourier Transform Infrared spectroscopy (FTIR) and Thermogravimetric analysis. It has been observed that polymerization of POM are greatly influenced by the method of preparation.
