    摘要: A method of manufacturing a hydrophobic coating material, including: (a) mixing a siloxane precursor, water, and a catalyst to proceed with a sol-gel reaction to form a solution having particles therein, wherein the sol-gel reaction is performed without using 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 coating material. A hydrophobic coating material and a hydrophobic coating formed by the hydrophobic coating material are also provided. The hydrophobic coating material may preferably have a low VOC (Volatile organic compound) value, and may disperse in a water phase solution.
