| 超疏水表面带来一些可贵的界面性质，包括防结冰、防污染、防氧化等。对于工业产品中常用的玻璃等无机材料，研究人员参照自然界超疏水物质的结构和成分，借助含碳、氟等元素的物质，通过各种方法，合成具有微米-纳米二重粗糙结构和低表面能的有机-无机杂化涂层与基材结合，从而制备超疏水表面。因玻璃表面亲水性的固有性质，在平板显示、触摸屏、太阳电池盖板、玻璃幕墙等领域，解决既能满足光学性能指标，又能实现疏水性和抗污染性的问题尤为重要。首先讨论了粗糙表面的固液复合接触和非复合接触两种理论模型，进而阐述了超疏水玻璃的实现要素和基于二氧化硅的超疏水膜的制备方法。梳理了以溶胶-凝胶法为基础的玻璃表面二氧化硅基透明超疏水膜的制备技术进展，根据涂膜次数、溶胶组成、膜层粗糙结构的实现方法等，将现有制备技术分类、归纳为三种制备路线：共前驱体合成改性二氧化硅溶胶制备单层超疏水膜，表面改性法制备多层结构超疏水膜，添加二氧化硅颗粒引入粗糙层法。指出了各种方法的超疏水原理、膜层特点，分析了部分制备实例的疏水性、粗糙结构、光学透过率等性质的影响因素。对于溶胶-凝胶法制备的SiO2基超疏水玻璃，实现超疏水性的同时，如何保持玻璃良好的透明性以及膜层的耐磨性、持久性，是需要重点研究的方向。 |

| The superhydrophobic surface brings some valuable interface properties, including anti-icing, anti-pollution, anti-oxidation, etc. For inorganic materials such as glass commonly used in industrial products, with reference to the structure and composition of superhydrophobic substances in nature, the researchers have synthesized organic-inorganic hybrid coating with micron- nanometer double rough structure and low surface energy with materials containing elements such as carbon and fluorine by various methods and prepared the super-hydrophobic surface. Due to the inherent hydrophilicity of glass surface, it is particularly important to solve the problem of both meeting the optical performance index and achieving hydrophobicity and anti-pollution in the panel display, touch screen, solar battery cover, glass curtain wall and other areas. Two theoretical models of solid-liquid composite contact and non-composite contact on rough surface were discussed firstly and then the implementation elements of superhydrophobic glass and the preparation methods of superhydrophobic film based on silica were described. For silica-based transparent superhydrophobic film on glass surface by sol-gel method, the development of preparation technology was reviewed. According to the number of coating times, sol composition, and the realization methods of the rough structures of the films, the existing preparation techniques were classified into three preparation routes, including synthesis of modified silica sol by co-precursor to deposit monolayer superhydrophobic film, surface modification method to prepare multilayer superhydrophobic film and method of adding silica particles to produce a coarse layer. Meanwhile, the principle of superhydrophobicity and the characteristics of the coatings by various methods were pointed out. For some examples, the factors influencing the properties of hydrophobicity, rough structure and optical transmittance were analyzed. For the SiO2 based superhydrophobic glass prepared by sol-gel method, how to maintain the good transparency of the glass, as well as the wear resistance and durability of the film layer is the focus of research in future. |
