摘要 以球状SiO2为原材料,采用层层组装法制备一级和二级微结构表面,通过SEM、接触角测量仪对其表面形貌与疏水性能进行表征,研究低表面能修饰、不同粒径、不同等级对其疏水性能的影响,并对其不同条件下的疏水稳定性进行研究。结果表明:经修饰后,薄膜都由亲水变为疏水;未修饰时,2 μm和20 nm SiO2复合的二级微结构疏水性能高于2 μm或20 nm一级微结构,修饰后也是如此,修饰后的二级微结构表面接触角为161.3°,滚动角为3.2°;二级微结构表面经240℃高温、紫外照射200 h仍能够保持良好的疏水性能。

Abstract:The spherical SiO2 was used as raw material to prepare the first-level and second-level microstructure surface by layer-by-layer assembly method. The surface morphology, hydrophobic properties were characterized by SEM and contact angle measurement instrument and then the effect of the low surface energy modifications, different size, different level on the hydrophobic properties was studied, and the hydrophobic stability under different conditions were studied. The results show that the film is changed from hydrophilic to hydrophobic after modification; before modification, hydrophobic performance of second-level microstructure with the mixture of 2 μm and 20 nm SiO2 is higher than 2 μm or 20 nm microstructure in the first level and it is the same after modification, whose contact angle and rolling angle of second-level microstructure is 161.3° and 3.2°, respectively. The second-level microstructure surface can still maintain good hydrophobic performance after experiencing 240℃ high temperature and 200 h ultraviolet irradiation.
