brief introduction：Superhydrophobic surfaces are already being used in processes such as self-cleaning, water-oil separation, water harvesting, and other fields. Surfaces are defined as superhydrophobic when they consist of densely packed protrusions on the nanoscale and/or microscale, with side walls that have tilt angles exceeding the advancing contact angle of water on the specific materials. This state is achieved by combining hierarchical roughness and low surface energy of the materials forming the surface. High aspect structures made of organic materials are, however, usually mechanically weak. The durability of superhydrophobic surfaces is an essential factor when considering practical applications. During the last decade, researchers invested significant time and effort into developing self-recovery superhydrophobic surfaces in order to broaden the range of further possible applications. An overview of self-recovery superhydrophobic surfaces is provided in this chapter, with a particular focus on the status of current fabrication processes and possible applications. In addition, an outlook on future fabrication techniques for creating robust and durable superhydrophobic surfaces is presented.
