    摘要:

    自然界中猪笼草的特殊润湿结构可用以捕获昆虫为其提供营养物质,受此启发,科研人员通过向微纳粗糙结构中灌注低表面能液体以形成稳定的润滑油层进而制备出注液超滑表面,其相较于一般的超疏水表面来说具有更为耐久的疏液、自清洁、防附着等性能,因而成为当今的研究热点。基于此,本文首先介绍了仿生超滑表面的润湿理论及作用机制;而后详细综述了超滑表面构建技术策略,包括粗糙基底成形-润滑油灌注与粗糙基底成形-基底化学修饰-润滑油灌注这两种典型路径;还全面论述了刻蚀法、溶胶凝胶法、呼吸图法,水热法等一系列超滑表面的制备方法;基于仿生超滑表面的优异性能,对其在油水分离、水雾收集、防腐蚀、液滴操控、抑菌以及防微生物粘附等领域的应用进展进行了深入讨论;最后,对仿生超滑表面的发展前景进行了展望以期为今后的研究提供参考。

    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.
