摘　　要：仿猪笼草唇叶结构的滑移功能表面(SLIPS)是通过将全氟液体、硅油或离子液体等润滑油注入到提前构建好的含有多孔或分级粗糙结构基底制备得到。由于毛细作用力和范德华力,动态油膜能够稳定锁定在粗糙基底中。所得到SLIPS的化学均相表面和特殊的液-固结合界使其展现出优异的液体排斥性、自修复性和高压稳定性等,并在近十年内成为表界面领域内研究热点。其应用领域主要包含防冻、防腐、防海洋污染和实现高透明性材料等,并在液体运输,太阳能电池表面和深海防污等领域展现出巨大应用前景。本文介绍了近五年来SLIPS主要制备与调控方法,还对其在防覆冰,防海洋生物污染与防菌,防腐和透明性等领域新的研究进展进行了阐述。最后,对滑移表面在未来的制备与应用所面临的挑战进行了展望。Nepenthes-inspired Slippery Liquid-Infused Porous Surface(SLIPS) is prepared by injecting lubricating oil like perfluorinated liquid, silicone oil or ionic liquid into a pre-constructed substrate that contains porous or hierarchical rough structures. Due to the capillary force and van der Waals force, the dynamic oil film can be stably locked in the rough substrate. SLIPS exhibits excellent liquid repulsion, self-healing properties, high-pressure stability because of chemically homogeneous surface and unique liquid-solid combined interface, and it has become a research focus in the field of surface interfaces in the past decade. Its application fields mainly include anti-icing, anti-corrosion, anti-marine fouling, high transparency materials, etc. Therefore, it exhibits tremendous application prospects in liquid transportation, solar cell surface, deep-sea anti-fouling, etc. After introducing the main methods of constructing the micro/nano structures required by SLIPS, the research progress in the fields of anti-icing, anti-marine pollution and anti-bacteria, anti-corrosion and transparency in the past five years have also been described in detail. Finally, the prospects of SLIPS in future application fields and challenges are envisaged.
