Modification of corrosion behavior of stainless steels with a poly-m-methoxytoluene coating

Poly-m-methoxytoluene (PMMT) coating is deposited on stainless steel. PMMT is synthesized via the anodic oxidation of the corresponding monomer, m-methoxtoluene (MMT) in acetonitrile solution containing tetrabutylammonium tetrafluoroborate (TBAF). The efficiency of PMMT coating against stainless steel corrosion has studied by standard electrochemical methods, electrochemical impedance spectroscopy (EIS) and SEM analysis. The results obtained suggest that PMMT film forms a sacrificial layer but the efficiency against corrosion is limited.
