Abstract: Superhydrophobic, a kind of special wetting ability, primarily originated from the "Lotus effect". It is defined as a special surface with a static contact angle of water droplets greater than 150° or a sliding angle less than 10°. This review introduces the research on superhydrophobic theory and phenomena in nature and summarizes methods of superhydrophobic surface preparation and applications in recent years. The advantages and disadvantages of the templating method, the coating method and the etching method are compared, and improvement measures of these methods are proposed. Besides, one of the most important applications of superhydrophobic surface to the metal corrosion resistance is emphasized. At last, the fabrication of superhydrophobic surfaces with special abilities is introduced, such as self-healing superhydrophobic surfaces, wetting reversal superhydrophobic surfaces. In these fabrication methods, the templating method and the etching method have advantages of time saving and low costing, but are usually accompanied by poor stability and abrasion resistance. The etching method is easier to control surface parameters, but limited in usefulness.
