摘要：

采用简单的低温水热法制备出ZnO微米棒薄膜，其经辛基三甲氧基硅烷和十二氟庚基丙基三甲氧基硅烷修饰后显示出超疏水性，静态接触角分别为(150±1.3)°和(155±1.5)°，滚动角依次为5°和3°。 ZnO微米棒的微结构和低表面能材料辛基三甲氧基硅烷、十二氟庚基丙基三甲氧基硅烷的表面修饰是其显示超疏水性的原因，用Cassie理论对膜的润湿性进行了分析。

关键词: 微米棒氧化锌薄膜, 接触角, 超疏水

Abstract:

ZnO microrod films has been prepared by simple low temperature hydrothermal approach. The films treated with octyltrimethoxysilane and dodecafluoroheptylpropyltrimethoxylsilane show super-hydrophobic properties. The static contact angles for water are (150±1.3)° and (155±1.5)°, and the slide angles are about 5° and 3°, respectively. It is believed that the super-hydrophobic property of the modified ZnO microrod films is mainly caused by the microstructures of the films and the modification of octyltrimethoxysilane or dodecafluoroheptyl-propyl-trimethoxylsilane with low surface energy on surfaces. The wettability of the ZnO submicrorod films is also discussed on the basis of Cassie theory.

Key words: ZnO microrod film, contact angle, super-hydrophobicity
