摘　　要：超滑氟硅涂层是一种新型的表面功能涂层,因其表面具有类似液体和分子光滑的特性而表现出良好的疏液、自愈合、防结冰、防指纹、防生物污损等性能,具有重要应用前景。本文介绍了超滑液体浸润涂层(或表面)和类液态高分子刷涂层2类超滑涂层的制备原理和性能特点。其中,前者通过超滑液体浸润多孔基底或溶胀于涂层基体之中获得,该涂层(或表面)润滑性强、自修复效果好,但易受侵蚀;后者通过氟硅高分子刷化学键合于基材表面或整个涂层基体之中制得,超滑性能相对较弱,但机械稳定性较好。进一步,重点介绍了2类超滑涂层的性能提升策略及已取得的进展。最后,指出了超滑涂层未来发展所面临的挑战。The fluoro/silicone based ultra-slippery coating is a new kind of surface functional coating,which exhibits excellent properties such as liquid repellency,self-healing,anti-icing,anti-fingerprints,and anti-biofouling properties due to the liquid-like surface and molecular smooth character,and hence has important application potential.In this paper,the preparation principles and characteristics of two types of ultra-slippery coatings including ultra-slippery liquid infused lubrication coating(or surface)and liquid-like polymer brush coating were described.The former was prepared by infusing the porous substrate with the ultra-slippery liquid or swelling it in the coating substrate.This ultra-slippery coating(or surface)had strong lubricity and self-healing effect,but were easily eroded.The latter was prepared by chemically attaching fluorosilicon polymer brush to the substrate surface or in the coating networks,and thereby showed relatively weak lubricity but better mechanical stability.Further,the performance enhance strategies and research advances of the two coatings were particularly introduced.Finally,future challenges on ultra-slippery coating were also proposed.
