目的 研究透明超疏水玻璃的制备及性能。方法 以纳米二氧化硅和无水乙醇为原料制成半透明乳液， 然后将乳液喷涂在玻璃表面， 再通过接触角测试、 透光率测试仪等手段对玻璃表面的性能进行研究。结果 在玻璃基材表面构建了与水滴接触角高达158°±2°， 滚动角低至1°的透明超疏水表面。当喷涂液中纳米二氧化硅的质量分数为1.5%时， 获得的超疏水玻璃表面具有优异的防水性、抗污易清洁性和透明性。结论 在玻璃基底上制备透明超疏水表面可以大大提高玻璃表面的防水、 防污性， 并使玻璃表面更易于清洁， 有利于减少玻璃包装材料清洗时的用水量和洗涤剂用量， 从而增强玻璃包装材料的生态环保效应。

This work aimed to investigate the preparation and properties of superhydrophobic glass surface. A translucent emulsion was prepared using nano SiO2 and ethanol as raw materials, and then the translucent emulsion was sprayed onto a common glass surface. The properties of prepared glass surface were studied by contact angle and transmittance testing instruments. A transparent superhydrophobic glass surface was obtained. The water contact angle and sliding angle of the superhydrophobic glass surface were 158°±2° and 1°, respectively. When the mass fraction of SiO2 was 1.5% , the as-prepared superhydrophobic surfaces showed excellent water repellency, anti-pollution and transparency. Fabricating transparent superhydrophobic surface on glass substrate could greatly enhance the water repellency and anti-pollution of glass. Superhydrophobic glass surface was easier to clean. It would be helpful to reduce the consumptions of water and detergent when the glass-based packaging materials were cleaned. It would also be helpful to enhance the ecology and environmental protection effect of glass-based packaging materials.
