DESCRIZIONE
The present invention provides a method for forming a superhydrophobic, superoleophobic or superamphiphobic layer and imparting said property to 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 a 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 the property to the surface or primed surface, wherein the dispersed silicone nanoparticles are formed by polymerizing at least one compound of formula I in an aprotic solvent comprising 5ppm to 500ppm water, RaSi(R1)n(X1)3‑n(I) Wherein R isaIs an aromatic group, a linear or branched C (1-24) alkyl or alkenyl group, R is a linear or branched C (1-24) alkyl group, which is linked to the Si atom by a single covalent bond or by a linear or branched alkylene unit having from 1 to 8 carbon atoms1Is a straight-chain or branched hydrocarbon radical having from 1 to 6 carbon atoms, X1Is a hydrolysable group which is one or more of a halogen or an alkoxy group, and n is 0 or 1, and preferably 0.
