| Abstract: | Poly(N-methyl carbazole) (PNMeCz) coating was deposited on 304 type stainless steel (SS) by electropolymerization of N-methyl carbazole monomer in tetrabutylammonium perchlorate containing acetonitrile solution using cyclic voltammetry. PNMeCz coating was characterized by attenuated total reflectance-Fourier transform infrared spectroscopy, scanning electron microscopy, thickness, conductivity, and contact angle measurements. Corrosion performance of the polymer-coated steel electrodes was investigated in 1 M H2SO4 solution using open circuit potential–time (Eocp–t) curves, potentiodynamic polarization, and electrochemical impedance spectroscopy techniques. PNMeCz coating was found to provide anodic protection to the substrate and significantly reduce the corrosion rate of SS in acidic medium. |
