Abstract In this paper, a simple powder scattering technology is utilized to fabricate superhydrophobic surface on tetra-needle like zinc oxide whiskers (T-ZnO)/silicon rubber (SR) and ordinary zinc oxide (O-ZnO)/SR composites, respectively. The microstructure of two surfaces is investigated by scanning electron microscope (SEM). Raman spectroscopy and X-ray diffraction spectroscopy are applied to qualitatively analyze substances on two superhydrophobic surfaces. The hydrophobicity and self-cleaning property of the surface are examined by contact angle meter and self-cleaning test, respectively. In addition, bounce performance of water droplets on the hydrophobic surface is tested via a highspeed camera. The results show that the static contact angle (CA) between water and surface of T-ZnO/SR is 154.26±1.2°, and the rolling angle (RA) is 5±1.8°. However, the static CA between water and O-ZnO/SR surface is 150.47±1.1° and the RA is larger than 90°. The superhydrophobic surface on T-ZnO/SR shows smaller adhesiveness to water and exhibits better self-cleaning property. Besides that, better bounce performance of water droplets on T-ZnO/SR superhydrophobic surface is realized.

一种简单的硅橡胶超疏水表面制备方法及其性能

摘要 本文利用简单的粉末散射技术分别在四针状氧化锌晶须（T-ZnO）/硅橡胶（SR）和普通氧化锌（O-ZnO）/SR复合材料上制备超疏水表面。通过扫描电子显微镜 (SEM) 研究两个表面的微观结构。拉曼光谱和 X 射线衍射光谱用于定性分析两个超疏水表面上的物质。表面的疏水性和自洁性分别通过接触角仪和自洁性试验进行检测。此外，通过高速相机测试疏水表面上水滴的弹跳性能。结果表明，T-ZnO/SR表面与水的静态接触角（CA）为154.26±1.2°，滚动角（RA）为5±1.8°。然而，水和 O-ZnO/SR 表面之间的静态 CA 为 150.47±1.1°，RA 大于 90°。T-ZnO/SR 上的超疏水表面对水的粘附性更小，并表现出更好的自清洁性能。除此之外，还实现了水滴在 T-ZnO/SR 超疏水表面上更好的反弹性能。
