Artificial (Biomimetic) Superhydrophobic Surfaces

Abstract

Artificial (biomimetic) superhydrophobic surfaces utilizing the Lotus effect are reviewed in this chapter. First, modern ways of production of superhydrophobic surfaces are discussed, including lithography, deposition, stretching, itching, evaporation, sol-gel, and others. The variety of materials used to make superhydrophobic surfaces (metals, polymers, semiconductors, nanotubes, nanoparticles) is discussed. Then wetting and self-cleaning properties of micro- and nanopatterned silicon and polymer biomimetic surfaces are presented on the basis of experimental measurements. After that, commercially available superhydrophobic products (paints, textiles, glasses) are reviewed as well as future applications in industry, bio- and nanotechnology.
