METHOD FOR MANUFACTURING AN EXTREMELY HYDROPHOBIC SURFACE

摘要

The invention relates to a method and an apparatus for producing a hydrophobic surface on to a material. The invention comprises directing at a surface to be structured a particle spray structuring the surface so as to structure the surface, and coating the structured surface with a hydrophobic material. According to the invention, particles larger than a determined size d2 are separated from the particle spray by at least one impaction nozzle (7, 11 ), which particles are directed at the surface (9) to be structured such that they collide with the surface (9) to be structured, producing a structure thereon. Next, the structured surface is coated by a gas deposition method in which the structured surface is subjected to alternate surface reactions of starting materials.
