| 目的 提高蒙砂玻璃的雾度以及调控其表面的亲疏水性。方法 通过在酸蚀液中添加不同浓度的KCl，可控调节蒙砂玻璃表面微纳结构，并利用光学轮廓仪对表面形貌和粗糙度进行表征分析。通过分光光度仪对蒙砂玻璃的雾度、透过率进行测试，并使用接触角测量仪对其亲疏水性进行分析评价。结果 通过调节酸蚀液中KCl的加入量，得到具有不同表面微结构及表面粗糙度的蒙砂玻璃。酸蚀液中KCl的加入，可以实现不损失玻璃透过率的同时，将蒙砂玻璃的雾度提高1个数量级，从4.23%提高至73.11%。酸蚀液中加入质量分数20%的KCl，可实现蒙砂玻璃表面较好的亲水性，接触角达20.9°，而玻璃原片的接触角仅为47.5°。在蒙砂玻璃表面涂覆十三氟辛基三乙氧基硅烷，100 ℃下热处理30 min，可实现蒙砂玻璃较强的疏水性，对水的接触角达到124.3°。结论 酸蚀液中加入KCl可以实现酸蚀蒙砂玻璃表面微结构的构建，并且通过控制KCl的加入量，提高蒙砂玻璃的透过率和雾度，实现较好的亲水性。用低表面能物质十三氟辛基三乙氧基硅烷成功对具有一定表面微结构的蒙砂玻璃进行修饰，将蒙砂玻璃由亲水性变为较强的疏水性。 |

| The work aims to improve the haze of frosted glass and control its surface hydrophilicity and hydrophobicity. The micro- and nano-structure of frosted glass surface was controlled by adding different concentrations of KCl into the etching solution. The surface morphology and roughness were characterized and analyzed by optical profilometer. The haze and transmittance of frosted glass were measured by spectrophotometer, and the hydrophilicity and hydrophobicity of frosted glass were analyzed and evaluated by contact angle measuring instrument. The frosted glass with different surface microstructure and surface roughness was obtained by adjusting the amount of KCl in the etching solution. The KCl in the etching solution can increase the haze of the frosted glass by one order of magnitude, from 4.23% to 73.11%, without decreasing the glass transmittance. By adding 20% KCl into the etch solution, the surface of the frosted glass was hydrophilic, with a contact angle reducing to 20.9°, while the contact angle of the original glass was only 47.5°. The surface of frosted glass was coated with 1H,1H,2H,2H-tridecafluoro-n-octyltriethoxysilane and heat-treated at 100 ℃ for 30 min to realize the strong hydrophobicity of the frosted glass and the contact angle of water reaching 124.3°. The surface microstructure of etched glass can be constructed by adding KCl into the etching solution, and the transmittance and haze of frosted glass can be improved by controlling the amount of KCl, so as to achieve better hydrophilicity. The low surface energy substance 1H,1H,2H,2H-Tridecafluoro-n-octyltriethoxysilane was used to modify the surface microstructure of the frosted glass, and the hydrophilic frosted glass could be changed into a strong hydrophobic glass. |
