Abstract:
    The present invention is method for forming hydrophobic transparent film on the surface of different substrates, glass, ceramic, metal, paint, etc. fluorosilane and other components are painted to the surface of plastic or paint with hydroxyl radical containing oxide film form in advance or the surface of other kind of substrate directly. Under the action of catalyst, the ethoxy group connected to the Si atom in fluorosilane is hydrolyzed into hydroxyl radical in advance, and the hydrolyzed solution is maintained in monohydric alcohol dihydrolic alcohol or other organic solvent, and the hydrolyzed fluorosilane reacts with the metal hydroxyl radical bond in the surface of the oxide to obtain high stability M-O-Si bonding. The formed film of several nanometer to decades nanometer thickness is firmly combined with the substrate chemically at normal temperature without need of heat treatment.
