Studies on super-hydrophobic films

Super-hydrophobic film is of promise prospect applied in various industrial products. But it is limited by preparing techniques for use as coatings of outside building and large equipments. It is the aim to search simple and effective methods to prepare and control the micro-nano-binary-structure to get super-hydrophobic coating. Here we briefly review the development of the theory and recent progress in the process and properties of super-hydrophobic films. It is a possible way to realize industrial production of super-hydrophobic coating with appropriate roughness and microstructure by the combination of different technologies such as sol-gel, phase separation and self-assembly of low surface-energy materials.
