A method for producing surfaces which have self-cleaning properties and a surface structure with elevations which are formed by the microparticles, the surfaces produced having not only self-cleaning properties but also oleophobic, lipophobic and lactophobic properties,
- the method comprising:
- hydrophobizing microparticles with fluorosilanes or fluorosiloxanes to form a surface structure, the surface structure having elevations with a mean height of from 20 nm to 25 μm and a mean separation of from 20 nm to 25 μm, the microparticles having a particle diameter of from 0.02 to 100 μm and having been hydrophobized with fluoroalkylalkoxysilanes.
