    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.

    摘要： Glass surfaces, for example, windshield surfaces, have a durable hydrophobic coating applied thereto. The glass surface is first treated by any suitable method to enhance the ability of a chitosan polymer coating to durably or substantially permanently adhere thereto. Once the chitosan coating has been applied to the glass surface, the normally hydrophilic chitosan coating is rendered hydrophobic by suitable treatment, for example, by a combination of enzymatic and chemical treatments. Alternatively, the chitosan may be rendered hydrophobic prior to coating it on the glass surface, but that is a less preferred technique. The method of the invention provides a glass article having a hydrophobic surface.
