| 中文摘要: |
| 自然界存在许多具有各向异性表面结构的生物,其表面表现出典型的对液体操控的方向性的差异。近年来,这种具有方向性差异的表面微结构的构筑由于其表现出的对液体方向性差异的操控能力而引起了广泛的研究兴趣,成为目前一个热点研究方向。天然的各向异性浸润表面是由复杂的异质微米纳米结构组成,我们出于基础研究和应用推广的目的可以将其简化为一些有序的方向性结构表面,文中给出了现在应用广泛的几种各向异性微纳米分级结构的构筑方法,并对比分析其可行性。同时我们还深入讨论了各向异性微纳米分级结构表面对于液体行为的调控。这种各向异性微纳米分级结构表面将在微流体运输、微流控芯片等领域有重要应用,也将对人类健康(比如生物芯片和重大疾病的早期诊断)、能源(比如电极材料的可控制备)和环境(比如污染物的分离及定向转化)等方面做出巨大的贡献。 |

| ThereSareSmanySnaturalSbiological anisotropic wetting surfaces, the surface showed a typical directional difference in the wetting behavior for water droplets. In recent years, the fabrication such micro-/nano- hierarchical structured material with directional differences has attracted a widely research interests because of its versatile applications in manipulating liquid droplet motions. Drawn inspirations from nature, building anisotropic structured surface is the key to realize the directional wetting behavior. Here, we summarize the recent research progresses on fabricating anisotropic micro-/nano hierarchical structured materials, as well as the typical directional wetting behavior on such surfaces with different topological nature. It has be proposed that the research could have promising applications in various fiels as microfluidic devices, water/oil separation and high efficient liquid collection etc. |
