Abstract: Fluoroalkyl silanes are a class of compounds useful for various industrial purposes. For example, fluoroalkyl silanes which have hydrolysable groups (called hydrolysable fluoroalkyl silanes), are compounds useful as surface treatment agents which provide durable hydrophobic and oleophobic coatings. In general, hydrolysable fluoroalkyl silanes can be represented with the following formula: (RO—)3Si—RT wherein R is H or an alkyl; and RT is a monovalent organic compound terminated by a perfluoroalkyl group. When used to coat a surface, the (RO—)3 moiety reacts (via hydrolysis) with various chemical groups of the surface (e.g., hydroxyl, amine, or other reactive groups) thereby bonding the fluoroalkyl silane to the surface The RT moiety comprises a divalent organic linking group which links the silicon atom to a terminal group rich in fluorine atoms whose unique electronic properties impart desirable hydrophobic and oleophobic properties in a surface coating.

Abstract: Inorganic particles hydrophobized with fluorosilanes have been used to impart hydrophobic as well as oleophobic properties as exemplified by U.S. Patent Application, US2006/0222815, filed by Oles et al. which teaches making such hydrophobized particles by the covalent bonding (i.e. grafting) of fluorosilanes upon the surface of inorganic particles (e.g. silica). The fluorosilanes employed by Oles et al. consist of a silicon atom having four bonds, three of which are direct bonds to hydrolysable groups which can react with the surface of an inorganic particle thereby covalently bonding the fluorosilane to particle. The remaining bond is a direct bond from the silicon atom to a perfluoroalkyl group. In contrast, the hydrophobized inorganic particles of the present invention comprise residues from fluorosilanes wherein the silicon atom is first bonded to a divalent organic linking group which in turn is bonded to a perfluoroalkyl group.
