摘要
通过简单的一步水热碱性刻蚀,然后经低表面能物质1H,1H,2H,2H-全氟辛基三乙氧基硅烷修饰,成功获得了具有超疏水性质和高透光率的玻璃表面.考察了刻蚀温度和刻蚀时间对玻璃润湿性和透光性的影响.结果表明,随着刻蚀温度的升高或刻蚀时间的增长,玻璃表面的疏水性越好;在所考察的刻蚀温度和刻蚀时间范围内,随着刻蚀温度升高或刻蚀时间增长,样品的透光率先增大后减小.此外,分析并讨论了玻璃表面微观结构对样品润湿性和透光性的影响.本研究在120 min,85℃实验条件下,获得了接触角为152°,滚动角小于4°,最大透光率达98.1%(537 nm)的玻璃表面.
A highly transparent superhydrophobic glass surface was successfully prepared through simple hydrothermal alkaline etching followed by modification with 1H, 1H, 2H, 2H-perfluorooctyl-triethoxysilane （POTS）. The effects of etching temperature and etching time were investigated on the wettability and transmittance of etched glass substrates. The results showed that the glass surface hydrophobicity is enhanced as the etching time or etching temperature increases; the transmittance of the samples first increases and then decreases as the etching temperature is elevated or the etching time increases. Besides, the effects of glass surface microstructures on their wettability and transparency were analyzed and discussed. In an optimized case, a glass surface was obtained with a water contact angle of 152~, a sliding angle of less than 4~ and the maximum transmission rate of 98.1% （537 nm）.
