Organic-inorganic composite films were prepared by adding different amount of nano-SiO2into water soluble acrylic resin (AC) on hot-dip galvanized steel sheet. The electrochemical behavior of nano SiO2 modified acrylic resin films in 5 % NaCl solution were studied by electrochemical measurement techniques. Results indicate when there are 8% ~ 12% SiO2 in organic film, it can shows an analogous passivation propertyin anodic polarization curves, increase anodic polarization function of galvanized coating, retarde lectrode reaction more efficiently. The reason is that either SiO2 in organic film occur chemical reaction with Zn, produce stable zinc silicate compound; or as aresult of dissolve-redeposit of SiO2 in the film.
