Superhydrophobic coating

Water-repellant coating

A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of coating can fully rebound. Generally speaking, superhydrophobic coatings are made from composite materials where one component provides the roughness and the other provides low surface energy.
