Zn片经水热反应和氟硅烷修饰构建超疏水ZnO表面

摘要:

以乙二胺为溶剂, Zn片在120、140 及160 ℃经水热反应生长出具有蛋糕形、荷叶乳突状、棒状和仙人球状等微结构的ZnO表面. 扫描电镜研究表明, 反应时间越长越有利于形成完整的微纳米结构, 反应温度较高生成的微纳米结构更规整. 140 ℃反应4 h和160 ℃反应5 h的ZnO表面经过氟硅烷修饰后表现出良好的超疏水性, 与水滴的接触角分别达到154.6°和157.3°, 滚动角分别为5°和3°. 该方法因其操作简便、成本低廉, 在锌表面制备特殊微结构和构建超疏水表面具有潜在的应用.

Abstract:

Cake-like, lotus leaf-like, trunk-like, and cactus-like ZnO surfaces grown directly on zinc substrates were fabricated by Zn foil hydrothermal reactions in an ethylenediamine solution at 120, 140, and 160 ℃. Scanning electron microscopy indicated that the micro-/submicro complex structures were more regular at longer reaction time and higher reaction temperature. The hydrophobicity of typical structured ZnO surfaces modified with a layer of fluoroalkylsilane were measured. Results showed that the structured surfaces prepared at 140 ℃ for 4 h as well as at 160 ℃ for 5 h exhibited superhydrophobicity with water contact angles of 154.6° and 157.3° as well as sliding angles of about 5°and 3°, respectively. This method may be used to fabricate various microstructured ZnO surfaces showing superhydrophobicity at a low cost.
