Abstract
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.
