Hydrophobic surface finish and method of application

摘要

The present invention relates to a method for hydrophobization of a fabric surface comprising providing a stream of a substantially anhydrous gas, passing said gas over or through a substantially anhydrous liquid of an alkylsilane, preferably a fluorinated alkylsilane to provide an alkylsilane, preferably a fluorinated alkylsilane vapor and bringing said vapor in contact with the fabric surface, thereby allowing the optionally fluorinated alkylsilane to bind covalently to the fabric surfaced. The present invention further relates to a fabric comprising a superhydrophobic surface finish prepared by a method of the invention and to a device for carrying out the method of the invention.
