A method for forming an inorganic passivation material is provided. The method includes mixing about 5 to 80 parts by weight of trialkoxysilane, about 10 to 80 parts by weight of tetraalkoxysilane, and about 1 to 30 parts by weight of catalyst to perform a reaction at pH of about 0.05 to 4 to form an inorganic resin material. The inorganic resin material is modified by phosphate ester to form an inorganic passivation material, wherein phosphate ester is about 0.1-10 parts by weight based on 100 parts by weight of the inorganic resin material. An inorganic passivation material and a passivation protective film produced therefrom are also provided.

A method of manufacturing a hydrophobic antifouling coating material, including: (a) mixing a sol-gel precursor, water, an aqueous colloidal silica suspension, and a catalyst to perform a sol-gel reaction to form a solution having particles therein, wherein the sol-gel reaction is performed without addition of any organic solvent; (b) chemically modifying the particles with a hydrophobic agent to form surface-modified particles; and (c) adding a surfactant to the solution containing the surface-modified particles to form a hydrophobic antifouling coating material. The hydrophobic antifouling coating material can be dispersed in an aqueous solution, and has properties such as low VOC (Volatile organic compound) value, high solid content, and high stability.
