PROTECTIVE BEHAVIOR AGAINST CORROSION OF POLY(N-METHYLANILINE) COATINGS ELECTROSYNTHESIZED ON STAINLESS STEEL SURFACE FROM SULFURIC ACID CONTAINING MONOMER SOLUTION

Thanks to their outstanding optical and electrical properties, potential polymers are one ofthe materials with the highest potential use in technological applications. In this study Poly(Nmethylaniline)coated stainless steel disc electrodes were obtained with N-methylaniline containingsulfuric acid solutions using constant potential, constant current and potentiodynamic techniques byelectrodeposition. Corrosion behavior of polymer coated electrodes were investigated by direct current(DC) polarization technique and linear anodic cyclic voltammetry in different aqueous (NaCl and HCl)solutions. Electrochemical techniques branching test results showed that the electroactive PNMAcoating can be used as a protective coating against rust for stainless steel. It was demonstrated that Nmethylanilineaniline and pyrrole with an aqueous solution of H2SO4 as the electrolyte can also showpositive copolymers and various coatings.
