A superhydrophobic ZnO thin film was fabricated by the Au-catalyzed chemical vapor deposition method. The surface of the film exhibits hierarchical structure with nanostructures on sub-microstructures. The water contact angle (CA) was 164.3 degrees, turning into a superhydrophilic one (CA < 5 degrees) after UV illumination, which can be recovered through being placed in the dark or being heated. The film was attached tightly to the substrate, showing good stability and durability. The surface structures were characterized by scanning electron microscopy and atomic force microscopy.
通过金催化化学气相沉积法制备了一种超疏水ZnO薄膜。该薄膜表面呈现出具有亚微结构上的纳米结构的分级结构。水接触角（CA）为164.3度，在紫外光照后转变为超亲水状态（CA < 5度），通过置于黑暗中或加热可恢复。该薄膜与基底紧密附着，表现出良好的稳定性和耐久性。通过扫描电子显微镜和原子力显微镜对表面结构进行了表征。
