Poly(o-ethylaniline) coatings were synthesized on copper (Cu) by electrochemical polymerization of o-ethylaniline in an aqueous salicylate solution by using cyclic voltammetry. The performance of poly(o-ethylaniline) as protective coating against corrosion of Cu in aqueous 3% NaCl was assessed by the electrochemical impedance spectroscopy (EIS). The results of these studies demonstrate that the poly (o-ethylaniline) coating has ability to protect the Cu against corrosion. The corrosion inhibition efficiency of coating is found to be 97%. The evaluation of the impedance parameters with immersion time was studied and water uptake and delamination area were determined. The variation of the water uptake and delamination area with the immersion time provides further evidence to the protective action of the poly(o-ethylaniline).
