Electrochemical synthesis of poly(o-anisidine) and its corrosion studies as a coating on aluminum alloy 3105
چکیده انگلیسی

The synthesis of poly(o-anisidine) coatings on aluminum alloy 3105 (AA3105) surface has been investigated by using the galvanostatic method. The synthesized coatings were characterized by reflection absorption infrared (RAIR) spectroscopy, UV–visible absorption spectrometry and scanning electron microscopy (SEM). Optical absorption spectroscopy reveals the formation of the emeraldine form of poly(o-anisidine). The anticorrosion performances of poly(o-anisidine) coatings were investigated in 3.5% NaCl solution by the potentiodynamic polarization technique Tafle and electrochemical impedance spectroscopy (EIS). The corrosion rate of poly(o-anisidine)-coated AA3105 was found ∼330 times lower than bare AA3105 and potential corrosion increases from −0.85 V versus SCE for uncoated AA3105 to −0.65 V versus SCE for poly(o-anisidine)-coated AA3105 electrodes. The results of this study clearly ascertain that the poly(o-anisidine) has outstanding potential to protect the AA3105 against corrosion in a chloride environment.
