The wetting transition is an abrupt change, spontaneous or induced by external stimulus, in the wetting properties of a flat or rough solid surface.

Wetting of Rough Surfaces and Wetting States

Wetting is a spreading of liquid on a solid or liquid substrate. It is ubiquitous and of primary importance in chemical, automobile, and food industries and medicine, soil, and climate sciences. Various technological applications call for surfaces with a controlled wettability, in particular water- and oil-repellent surfaces. Rapid progress of nanotechnologies has allowed the fabrication of biomimetic surfaces demonstrating pronounced water repellence (the so-called lotus effect [1]). A variety of natural objects, such as birds’ and butterflies’ wings and legs of water striders, demonstrate extreme water repellency (superhydrophobicity, which is one of the surface tension effects of nanostructures) [2, 3, 4]. Various sophisticated experimental techniques, including UV lithography and...
