Abstract—In this study, Polyaniline (PANI) and Polianiline/nano metal oxide (SnO2, ZnO (0.1, 0.3 and 0.5 wt %)) are coated on the surface of the steel electrode by galvanostatic method. PANI, PANI/SnO2 and PANI/ZnO coatings were obtained at constant current 50 mA and 1200 s. Characterization of galvanostatically obtained coatings was carried out by FT-IR spectroscopy, XRD and SEM. The effectiveness of PANI, PANI/SnO2 and PANI/ZnO nanocomposite coating in preventing steel corrosion was investigated in 3% NaCl solution using the potentiodynamic polarization technique and electrochemical impedance spectroscopy. The experimental results indicate that as the amount of nanometal oxide (SnO2, ZnO) in the polymer matrix increases, the steel corrosion is reduced.
