Self cleaning surfaces due to hydrophobic structures and method for the preparation thereof

The present invention relates to self-cleaning surfaces which have a have self-regenerating self-cleaning effect and process for their preparation. The economic importance of equipped with self-cleaning surfaces Objects continues to increase. It is therefore object of the developments in this Area, to easily provide self-cleaning surfaces, the longer exhibit self-cleaning action than the previously known surfaces. In the present invention this object is achieved in that self-cleaning hydrophobic surfaces are produced on the surface (O) by means of a carrier (T) fixed particles (P), wherein the carrier (T) itself, a mixture of particles (P) and binder, so by erosion, the particles (P) are removed at the surface, but also new Particles (P) from the carrier (T) are exposed and the self-cleaning effect in this way regenerates itself. The self-cleaning surfaces can especially outdoors, such. As to Vehicles, are used to advantage, since the self-cleaning materials to Environmental influences are particularly exposed.
