Abstract

In this study, a nano-structured surface was prepared on glass slides by RF magnetron sputtering with zinc target. The superhydrophobicity of the surface was highly improved after thermal oxidation and decorated by hexadecyltrimethoxysilane. Field emission scanning electron microscopy (FESEM) and energy dispersive spectrometer (EDS) were utilized to evaluate the surface morphology, element types and levels of the samples. A portable low-temperature test chamber was used to investigate the anti-icing performance of the superhydrophobic surface and record the collision process of a cooling water drop to the sample surface by high-speed camera. The results showed that the frozen temperature of water droplet on the superhydrophobic surface was much lower than that of droplet on the bare glass. This study offers insight into understanding the anti-icing behavior of the superhydrophobic surface and may favor the application of superhydrophobic surfaces in power transmission system against ice accumulation.

射频磁控溅射制备超疏水表面及其防冰性能

本研究采用射频磁控溅射法制备了含锌靶片的纳米结构表面。经热氧化和十六烷基三甲氧基硅烷修饰后，表面的超疏水性得到了极大的改善。利用场发射扫描电镜(FESEM)和能谱仪(EDS)对样品的表面形貌、元素类型和含量进行了表征。采用便携式低温实验箱研究了超疏水表面的防冰性能，并通过高速摄像机记录了冷却水水滴与样品表面的碰撞过程。结果表明，超疏水表面水滴的冻结温度远低于裸玻璃表面水滴的冻结温度。该研究为了解超疏水表面的防冰行为提供了新的思路，有助于超疏水表面在输电系统中防冰的应用。
