The invention relates to a method and an apparatus for producing a hydrophobic surface on to a material. The invention involves 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, which particles are directed at the surface to be structured such that they collide with the surface 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.
A method of producing an extremely hydrophobic surface having a contact angle greater than 120 degrees on to a material, the method comprising 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, wherein the method comprises at least the following steps of:
