我们描述了一种在160°C溶剂热合成的玻璃载玻片上制备co3o4薄膜的简单方法。经表面改性后，制备的膜具有优异的超疏水性和良好的自清洁性能。结果表明，最大水接触角约为169.2°，滑动角小于3°。更重要的是，这种薄膜具有优异的防冰性能：对于放置在- 4.6至- 5.0°C表面的球形水滴，冰不会形成超过66分钟。这种超疏水薄膜在未来具有重要的工业应用价值。
We describe a simple method to prepare Co3O4films on glass slides fabricated via solvothermal synthesis at 160 °C for 90 min. After the surface modification, the prepared films show extraordinary superhydrophobicity and good self-cleaning performance. The results indicate that the maximum water contact angle is approximately 169.2° and sliding angle is less than 3°. More importantly, such films exhibit excellent anti-icing properties: for a spherical-like water droplet placed on the surface at −4.6 to −5.0 °C, ice cannot be formed for more than 66 min. The super-hydrophobic films could have significant industrial applications in the future.
