摘要：

A self-assembled films (SA) of cupper phthalocyanine (CuPh) chemisorbed on the mild steel surface was coated by an inorganic-organic sol gel hybrid coating. Hybrid sol was synthesized via acid catalyzed hydrolysis and condensation of methacryloxypropyl trimethoxysilane (TMSM) and tetraethoxysilane (TEOS) at the molar ratio of 1: 1. The morphology of mild steel coated with TMSM/TEOS and CuPh was examined by SEM. The surface chemistry of the hybrid sol-gel coatings was investigated with polarization scans and electrochemical impedance spectroscopy (EIS) in aerated 0.5 mol L-1 HCl solution. Self assembled CuPh films coated under the hybrid coating showed a strong influence on its corrosion resistance, mainly when the samples have 24 h immersion time and 1 mM concentration.
