Abstract
Particles with a structural surface which are useful to produce abrasion resistant self-cleaning surfaces contain particulate solid particles having a superstructured overlayer of fine particles. The particles may be prepared by polymerizing a polymerizable siloxane, silane, or mixture thereof in a Pickering emulsion.
