Microroughness and nanoroughness

The roughness of an superhydrophobic (water repelling) surface contains two types of roughnesses; microroughness and nanoroughness. Microroughness forms the overall topography of the surface and nanoroughness is located on the top of microroughness.

Mechanical destruction of the surface roughness will diminish the superhydrophobicity of the surface, which can increase the ice adhesion considerably.
