    摘要： Sol-gel coating formulations including metal oxide particles such as aluminum oxide, calcium oxide, zinc oxide, magnesium oxide, and molybdenum oxide embedded in a hybrid polymer matrix based on a reacted form of a resin composition containing a tetraalkylorthosilicate, an aminoalkylsilane, a dialkoxysilane, and a silanol terminated polydimethylsiloxane. The sol-gel coating formulations are suitable for applications such as anticorrosive protective coatings of metal substrates (e.g. mild steel). These anticorrosive coated metal substrates are evaluated on their hydrophobicity (water contact angle), surface roughness, mechanical strength (e.g. hardness), adhesiveness to the substrate (e.g. critical load), and anticorrosiveness upon exposure to a saline solution (e.g. impedance value).
