摘要： Substrates have a hydrophobic surface coating comprised of the reaction products of a chlorosilyl group containing compound and an alkylsilane. Most preferably the substrate is glass. In one embodiment, highly durable hydrophobic coatings may be formed by forming a silicon oxide anchor layer or hybrid organo-silicon oxide anchor layer from a humidified reaction product of silicon tetrachloride or trichloromethylsilane, followed by the vapor-deposition of a chloroalkylsilane. Such a silicon oxide anchor layer will advantageously have a root mean square surface roughness of less than about 6.0 nm and a low haze value of less than about 3.0 %. Another embodiment includes the simultaneous humidified vapor deposition of a chlorosilyl group containing compound and a chloroalkylsilane. In preferred embodiments, the simultaneous vapor deposition onto a glass substrate of silicon tetrachloride and dimethyldichlorosilane results in a hydrophobic coating comprised of cross-linked polydimethylsiloxane, which may then be capped with a fluoroalkylsilane. The cross-linked polydimethylsiloxane layer may be formed on the surface of the glass substrate, or a silicon oxide anchor layer may be deposited under the cross-linked polydimethylsiloxane layer.
