Polyaniline has been electrochemically formed on stainless steel in sulphuric acid N with and without KClO3. The CV spectrum style and the peak characteristic parameters, as peak potential Ep, peak current Jp, peak charges quantity Qp, then have been analyzed under a consideration of the effect of KClO3. The resistance of the PANi films was studied using electrochemical impedance measurement. It has been found that KClO3 has affected the PANi morphology much more than the CV spectrum.
