摘要
液滴在润湿异性表面的定向运动具有重要应用价值,如油水分离、水收集等,已成为表界面领域的研究热点。开展润湿异性表面液滴定向运动研究,对于理解固-液相互作用、开发高性能润湿异性表面具有重要意义。从楔形表面、沟槽阵列表面、亲水-疏水表面、非对称形貌表面和生物表面等角度,详细介绍了润湿异性表面液滴定向运动的最新研究进展,展示了国内外典型研究工作,对未来研究工作的重点进行了展望。
Research of the droplet movement on the wetting of the heterogeneous surface has important application value in,for example,oil-water separation,water collection,etc.,and has become a research hotspot in the field of surface interface.In addition,the research on the directional motion of the the droplets on wetting anisotropic surface is of great significance for understanding the solid-liquid interaction and developing a high-performance wetting anisotropic surface.This paper introduces the directional movement of droplets on the wetting anisotropic surface in detail including the wedge-shaped surface,groove surface,hydrophilic-hydrophobic surface,asymmetric topography surface and biological surface.The typical cases of directional movement of droplets on a wetting anisotropic surface at home and abroad are shown.Finally,a summary and prospect are provided for future research.
