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.
The glass with superhydrophobic property and high transmittance was successfully obtained by a simple one-step hydrothermal alkaline etching followed by 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane modified by low surface energy Surface.The effects of etching temperature and etching time on the wettability and light transmission of glass were investigated.The results show that the hydrophobicity of the glass surface is better with the increase of etching temperature or etching time, With the increase of etching temperature or etching time, the light transmittance of the sample first increases and then decreases in the investigated etching temperature and etching time.In addition, the influence of the glass surface microstructure on the sample run Wettability and translucency.In this study, the glass surface with the contact angle of 152 °, the roll angle of less than 4 ° and the maximum transmittance of 98.1% (537 nm) was obtained under the conditions of 120 min and 85 ℃.
