Abstract Surface wetting behavior is of great importance in determining the application of various materials. Manyphysicochemical processes , such as adsorption , lubrication , adhesion , dispersion , friction and so forth are closely relatedwith the wettability of materials. In the last decade , surfaces with ultra hydrophobicity have aroused much researchinterests owing to their potential application in self2cleaning coatings , microfluidics and patible materials and soon. The recent progress in the study of superhydrophobic surface is summarized in three parts. In the first part thecharacterization and influences of wettability are briefly introduced; in the second part new development ofsuperhydrophobic surfaces is summarized from both experimental and theoretical aspects; in the third part the prospect
ofthe development in this field is proposed. Key words superhydrophobic ; lotus-leaf-like ; hierarchical structure ; hysteresis; contact angle ; sliding angle
