| 中文摘要: |
| 以商品化SiO2 气凝胶为原料,选择不同的分散介质进行分散,然后在玻璃表面进行涂覆并干燥,制得超疏水表面。研究结果表明:当选择丙酮作为分散介质,SiO2 气凝胶质量浓度为30g/L,以旋涂的方式涂覆2次,并于20℃进行干燥时,所制备的表面超疏水效果最好,其接触角为153.2°,滞后角为1.7°。 |
| 英文摘要: |
| Superhydrophobic glass was prepared by coating and drying with different dispersion medium based on commercialized silica aerogel. It is found that a superhydrophobic surface with a contact angle of 153.2° and a contact angle hysteres is of 1.7°can be achieved under the following conditions: acetone as the solvent, SiO2 aerogel concentration of 30 g/L, spining coating twice, drying temperature of 20 ℃. |
