摘要：以疏水纳米 SiO 2 和中性硅酮结构胶为主要原料，采用喷涂法在玻璃表面制备出透明超疏水 SiO 2 /硅酮胶
复合涂层。采用 FTIR、SEM、接触角测量仪和紫外-可见分光光度计对复合涂层的分子结构、微观形貌、润湿
性和透光率进行表征。讨论了纳米 SiO 2 的添加量与涂层表面微结构、水接触角、透明性三者的关系，考察了复
合涂层的耐水冲击性能和耐水稳定性能。结果表明：SiO 2 /硅酮胶复合涂层表面呈连续的多孔网络状，团聚的 SiO 2
纳米粒子分散在作为骨架的亚微米级硅酮胶周围，构成了微纳米双尺度的复合粗糙结构。当 SiO 2 质量分数为
2.0%时，复合涂层的水接触角达到最大为 169.8°±0.7°，在 380~760 nm 可见光范围内的平均透光率为 82.9%；
当硅酮胶质量分数为 4%时，复合涂层分别经 5 h 水冲击以及 10 d 水浸泡后，水接触角仍保持在 140°以上。

Abstract: Transparent superhydrophobic SiO 2/silicone sealant composite coatings were prepared by spray
coating method using hydrophobic nano-SiO 2 and neutral silicone structural sealant as main raw materials.
The molecular structure, microstructure, wettability and light transmittance of the composite coatings were
characterized by FTIR, SEM, contact angle measurement and UV-Vis spectrophotometer. The relationship
between the content of nano-SiO 2 and the surface microstructure, water contact angle and transparency of
the coatings was discussed. The water impact resistance and water stability of the composite coatings were
also studied. The results showed that the surface of the SiO 2/silicone sealant composite coating displayed a
continuous porous network structure, and the aggregated SiO 2 nanoparticles were dispersed around the
sub-micron silicone sealant as the backbones, forming the micro-nano composite rough structures. When
the mass fraction of nano-SiO 2 was 2.0%, the maximum water contact angle of 169.8°±0.7° and the
average transmittance of 82.9% under visible range from 380 nm to 760 nm were obtained. In addition,
when the mass fraction of silicone sealant was 4%, the water contact angle of the composite coating
remained above 140° after 5 h water impact and 10 d water immersion, respectively.
