    Abstract:

    Nepenthes pitcher plant, its special wetting structure were used to capture insects for supplying nutrients, which inspiring researchers infused lubricant with low surface energy to preparation slippery liquid-infused surface. Compared with superhydrophobic surface, it has more durable characteristic such as hydrophobicity, self-cleaning, anti-adhesion and etc, hence it has become a research hotspot. Based on above mentioned, firstly, the wetting theory and mechanism of action of biomimetic super-slippery were introduced. Secondly, the construction strategy of super-slippery surface was reviewed in detail, including two basic path, one type is rough substrate forming-lubricating oil infusion; other type is rough substrate forming-chemical modification of substrate-lubricating oil infusion. A series of preparation method of super-slippery surface such as etching, sol-gel, breath figure, hydrothermal, were also discussed comprehensively. In view of the excellent properties of super-slippery surface, its application progress in the fields of oil-water separation, fog collection, anti-corrosion, droplet manipulation, anti-biofouling and bacterial adhesion were expounded in depth. Finally, the prospect of biomimetic super-slippery surfaces is prospected, in order to bring reference for future research.
