摘要
The present invention provides for method for forming a superhydrophobic, superoleophobic or superamphiphobic layer and imparting said property on a surface, comprising the steps of: a. preparing a liquid coating composition comprising a solvent and dispersed silicone nanoparticles, b. optionally priming the surface to form a primed surface on which a superhydrophobic, superoleophobic or superamphiphobic layer is to be formed, c. applying a layer of the liquid coating composition on the surface or primed surface on which the superhydrophobic, superoleophobic or superamphiphobic layer is to be formed, d. evaporating the solvent from the liquid coating composition to form a superhydrophobic, superoleophobic or superamphiphobic layer and impart said property on the surface or primed surface, wherein the dispersed silicone nanoparticles are formed by polymerization of at least one compound of formula I in an aprotic solvent comprising 5 to 500 ppm of water, RaSi(R1)n(X1)3-n (I) wherein Ra is a straight-chain or branched C(1-24) alkyl or alkenyl group, an aromatic group which is linked by a single covalent bond or linked by a straight-chain or branched alkylene unit having 1 to 8 carbon atoms, to the Si-atom, R1 a straight chain or a branched hydrocarbon radical having 1 to 6 carbon atoms, X1 is a hydrolysable group, which is one or more of a halogen or an alkoxy group, and n is 0 or 1, and preferably is 0.
