| 中文摘要: |
| 基于室温硫化硅橡胶(RTV)技术,以端羟基聚硅氧烷(107 硅橡胶)为成膜树脂,添加纳米二氧化硅粒子,在室温下制备出超疏水涂层,对其表面形貌和疏水性进行了表征和分析。结果表明,涂层表面具有类似荷叶的微米-纳米双重结构,其水滴静态接触角可达165°,滚动角仅为3. 8°。通过覆冰试验发现,超疏水涂层在初期阶段降低了覆冰的增长速率,具有明显的防覆冰效果。 |
| 英文摘要: |
| Based on the technique of RTV, the superhydrophobic coating was prepared at room temperature by using hydroxyl-terminated polydimethylsiloxane as the film-forming resin which combined nanometer silicon dioxide with different size.The morphology of coating surface was characterized and the hydrophobic performance was analyzed. The results indicate that there is a micro-nano binary structure similar lotus leaves on coating surface, which can make the highest static state contact angle of 165°and the lowest slide angle of 3. 8°between coating surface and water droplet. It is found via icing test that the super-dydrophobic coating made via this method has obvious anti-icing effect due to it can delay the growth rate of icing process during the early period. |
