摘要：
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 (E-ocp-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.
