中文摘要:

      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。

英文摘要:

      Investigating the preparation and properties of superhydrophobic glass surface.A translucent emulsion was prepared using nano SiO2 and ethanol as raw materials at first, 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 is 1.5%, the as-prepared superhydrophobic surfaces showed excellent water repellency, anti-pollution and transparency.Fabricating transparent superhydrophobic surface on glass substrate can greatly enhance the water repellency and anti-pollution of glass. Superhydrophobic glass surface is easier to clean than common one. It is helpful to reduce the consumptions of water and detergent when the glass-based packaging materials were cleaned. It is also helpful to enhance the ecology and environmental protection effect of glass-based packaging materials.
