Claim:
1. A method for modifying a surface of a substrate to form a superhydrophobic surface at least on parts of the substrate, comprising a functionalization step of functionalizing at least the surface of the substrate by covalently binding an alkyne or alkene group-containing compound thereto to form an alkyne or alkene functionalized porous surface, wherein the alkyne or alkene group-containing compound represents a monomeric moiety; and a first modification step of modifying the alkyne or alkene functionalized porous surface by reacting the alkyne or alkene groups with at least one first compound selected from the group consisting of thiols, disulfides and tetrazoles, wherein the first modification step is carried out at least on parts of the alkyne or alkene functionalized porous surface of the substrate and under UV irradiation, wherein superhydrophobic areas on the surface are formed in the functionalization step and/or first modification step, and wherein the static water contact angle (WCA) (θ
