| 中文摘要: |
| 对于太阳能电池系统、汽车挡风玻璃、相机镜头等光学器件，高透明性是其功能的最重要指标之一。由于这些设备经常暴露在室外，大量的灰尘污垢会严重影响其性能。透明超疏水表面由于具有优异的光学和抗污性能，在光学器材领域有着很高的应用前景。首先总结了表面润湿性理论，主要包括Young润湿方程、Wenzel润湿模型和Cassie润湿模型，通过润湿性理论指出制备超疏水表面的条件——低表面能物质和粗糙结构二者缺一不可。其次，讨论了粗糙度和透明度之间的竞争关系，通过瑞利散射和米氏散射理论，得出制备透明超疏水表面还需要同时满足材料表面粗糙度小于100 nm。然后，归纳总结了近十年来透明超疏水表面常见的制备方法，如溶胶凝胶法、化学气相沉积法、模板法、相分离等方法，并对这些制备思路和方法进行了分析，概括了这些方法当前存在的一些问题。最后，简单介绍了透明超疏水表面在太阳能电池、光学元器件、光催化材料等领域的应用，并对透明超疏水表面的未来研究方向和应用前景进行了展望。 |

| High optical transparency is one of the most crucial criteria for the overwhelming majority of optical devices, such as solar cell system, windscreen, and camera lens, etc. The properties of these devices may be seriously influenced by large amounts of dust and dirt, because they are exposed to the outdoor environment frequently. Transparent super-hydrophobic surface has a high prospect in the field of optical equipment by virtue of its excellent optical properties and anti-fouling properties. This paper firstly summarizes the theory of surface wettability, mainly including Young wetting equation, Wenzel wetting model and Cassie wetting model, and based on the theory of wettability, it puts forward the conditions of preparing super-hydrophobic surface:namely low surface energy substance and rough structure into the material surface, both of which are indispensable. Secondly, the competitive relationship between roughness and transparency is discussed, and through sorting out the Rayleigh scattering and Mie scattering theory, this paper finds that the surface roughness shall be less than 100 nm, which is the essential condition for the preparation of transparent super-hydrophobic surface. Thirdly, this paper summarizes the common preparation methods of transparent super-hydrophobic surface in recent ten years, such as sol-gel method, chemical vapor deposition method, template method, and phase separation method, etc. It also analyzes these preparation ideas and methods, and summarizes some problems existing in these methods accordingly. Finally, this paper briefly introduces the application of transparent super-hydrophobic surface in the field of solar cells, optical components, and photocatalytic materials, etc., and forecasts the future research direction and application prospect of transparent super-hydrophobic surface. |
