摘要水滴在超疏水表面上反弹的能力是表面润湿性能的重要指标。报道了一种将水热合成与超精密加工相结合的方法来制备层次化NiO-Fas-17涂层铜微槽表面的方法。通过接触角和水滴回弹行为来评价样品表面的疏水性。结果表明，NiO-Fas-17涂层具有较大的接触角在160°以上，较小的接触角滞后不超过5°，具有良好的拒水性能。结果表明，与NiO-Fas-17涂层平板相比，NiO-Fas-17涂层微槽表面的液滴第一次反弹高度更大，液滴破碎倾向更强，说明层状表面具有更好的疏水性。这表明，通过将UPM制造的微槽图案引入到已经具有良好疏水性的纳米结构表面中，可以增强表面的疏水性。
Abstract The ability of a water droplet to bounce on a superhydrophobic surface is an important indication of the surface wetting properties. In this study, a method integrating hydrothermal synthesis with ultraprecision machining (UPM) is reported for fabricating a hierarchical NiO-FAS-17 coated copper microgroove surface. Contact angles and water droplet bouncing behaviors were tested to evaluate the hydrophobicity of sample surfaces. Large contact angles over 160° and small contact angle hysteresis not exceeding 5° were recorded, showing good water repellency for the NiO-FAS-17 coating. The droplet bouncing results presented a larger first rebound height and stronger tendency of droplet break-up on the hierarchical NiO-FAS-17 coated microgroove surface in comparison with the NiO-FAS-17 coated flat surface, indicating a better hydrophobicity of the hierarchical surface. This reveals that the hydrophobicity of a surface can be enhanced by introducing UPM fabricated microgroove patterns into nanostructured surfaces that already possess good hydrophobicity.
