Progress in biomimetic superhydrophobic surface coating

The theoretical models related to wetting of solid surface were described, and several low surface energy materials in common use for superhydrophobic surface coating were summarized at first. Then the latest trends in the study on superhydrophobic surface coating materials were discussed combining with the construction methods of rough surface. Some problems in superhydrophobic coating materials research were pointed out, and the application prospects of superhy-drophobic coating materials in oil transportation, biosensor, microfluidic devices and intelligent separation membrane were also discussed. It's an effective approach to obtain superhydrophobic surface coating to combine the modification of low surface energy materials with the construction methods of rough surface.
