Claim:
1. A method for the production of a superhydrophobic film, or surface on a substrate comprising the steps of: (i) providing a composition comprising a hydrophobic substance and a hydrophilic solvent, said hydrophilic solvent being a liquid at a temperature of 25° C. and atmospheric pressure; and (ii) spraying said composition towards the substrate for deposition of a solid residue onto the surface of said substrate for generation of said superhydrophobic film, or surface; wherein the temperature of said composition is 30 to 100° C. higher than the temperature of said substrate and the temperature of the substrate is at least 10° C. lower than the melting point of the hydrophobic substance when carrying out step (ii).
