    摘要： The invention provides a method for forming a hydrophobic coating on the surface of a solid substrate, the method comprising: a) applying to the surface a composition comprising hydrophobic nano-sized particles, wherein at least some of the hydrophobic nano-sized particles are particles having at least one fluoro-substituted non-polar group on the surface of the particle; and b) curing the applied composition to form a coating bound to the surface, wherein the nano-sized particles provide the surface of the coating with nano-scale roughness. The method can be used to form a hydrophobic and lyophobic coating on the surface of a textile.

    摘要： Bisperfluoroalkyl-substituted diols of formula I

    wherein

    R₁ is a direct bond, a linear or branched alkylene of up to 6 carbon atoms, alkyleneoxy-alkylene of up to 6 carbon atoms, alkylenethioalkylene of up to 6 carbon atoms, alkyleneoxy of up to 6 carbon atoms, alkenyleneoxyalkylene of up to 6 carbon atoms, alkylenethioalkyleneoxyalkylene of up to 9 carbon atoms, carbonamidoalkylene where the alkylene moiety contains up to 6 carbon atoms and the amido nitrogen is unsubstituted or further substituted by lower alkyl, sulfonamidoalkylene wherein the alkylene moiety contains up to 6 carbon atoms and the amido nitrogen is unsubstituted or further substituted by lower alkyl; carbonamidoalkylenethioalkylene wherein the carbonamidoalkylene moiety is as defined hereinabove and the thioalkylene moiety contains up to 6 carbon atoms, or sulfonamidoalkylenethioalkylene wherein the sulfonamidoalkylene moiety is as defined hereinabove and the thioalkylene moiety contains up to 6 carbon atoms,
    R x , R y and R z are independently of each other hydrogen or an alkyl group with 1-5 carbon atoms,
    h is 1 or 2,
    x is 0, 1, or 2, with the proviso that when h is 2, x is 0,
    d is 0 or 1,
    D is an alkylene group with 2 to 10 carbon atoms, a dialkylene ether group with 4 to 10 carbon atoms, or pentaerythritol diacetate or dipropionate, and
    R F is a monovalent, perfluorinated, alkyl or alkenyl, straight, branched or cyclic, organic radical having 3 to 20 fully fluorinated carbon atoms, which radical can be interrupted by one or more divalent oxygen or sulfur atoms, and each R F radical is the same or different, and
    a method for making them are described. These diols can react with isocyanates to form urethanes; diisocyanates to form polyurethanes; chloroformates to form carbonates; with carboxylic, sulfuric or phosphoric acids or derivatives to form carboxylate esters, sulfate esters, phosphate esters respectively. These diol compounds and their derivatives are useful for imparting oil and water repellency to substrates such as glass, wood, paper, leather, wool, cotton, polyester and other substrates.
