ABSTRACT:
A self-regenerating, self-cleaning hydrophobic surface is formed when particles are secured on a carrier that is itself a mixture of particles and binder. When particles on the surface are ablated by erosion, new particles in the carrier are exposed to regenerate the self-cleaning surface, resulting in a long-lasting self-cleaning action. The self-cleaning surface may be used with particular advantage outdoors, e.g. on vehicles, where self-cleaning materials are particularly exposed to the effects of the environment.
