A novel method for producing superhydrophobic surfaces

摘要

The present invention provides a method for the production of a superhydrophobic film, surface or material comprising the steps of: (i) providing a composition comprising a hydrophobic substance and a hydrophilic solvent, the hydrophilic solvent being a liquid at a temperature of 25° C. and atmospheric pressure; and (ii) spraying the composition towards a substrate for deposition of a solid residue onto the surface of the substrate for generation of the superhydrophobic film, surface or material; wherein the temperature of the composition is higher that the temperature of the substrate when carrying out step (ii). A composition, use of the composition and a substrate is also provided.
