A supper hydrophobic surface (e.g., autoclean surface) and methods of making such a surface. The method includes forming an open porosity on a surface of a product, the open porosity including pores having undercuts and attaching functional nano-particles to the surface, such that the functional nano-particles are located inside the open porosity. The open porosity is formed by various methods such as, for example, co-extruding or applying a polymeric material with a blowing agent and/or etching the surface and/or directly printing a porous layer on the surface. |
