Research Progress of Super-Hydrophobic Films

Hydrophobic film technology have been applied in many fields of modern industry.Three different solid surface wetting models and contact angle equations were introduced.The two necessary conditions of the preparation of super-hydrophobic solid surface including low energy surface and special micro surface roughness were elucidated from the wetting theory of solid surface.Meantime,the hydrophobic materials in common use including compounds containing silicon and fluorine,several main preparing methods of rough solid surface,dynamic super-hydrophobic and application prospects of super-hydrophobic films were reviewed in this paper.
