摘要

以纳米晶ZnO薄膜为基底,碱式醋酸锌的悬浊液为生长液,在60℃条件下生长成ZnO纳米棒阵列薄膜,薄膜的粗糙表面由微米尺度和纳米尺度的微结构相结合而构成。扫描电子显微镜分析表明,所合成的薄膜表面含有直径50~100μm的蚯蚓状突起,同时薄膜表面生长有直径约30nm和150nm两级尺寸分布的纳米棒。这种微/纳结构的结合有效改善了薄膜表面的疏水性能,薄膜表面经辛基三甲氧基硅烷处理后呈现超疏水性,接触角达到155.7°。

Abstract

ZnO nanorod array films with rough surface created by micro-sized and nano-sized structures were allowed to grow on nanocrystalline ZnO substrate at 60℃ by using basic zinc acetate suspension as a growth solution.The SEM observation indicated that earthworms-like apophyses with a diameter about 50~100μm and ZnO nanorod with bimodal diameter distributions centralized about 30nm and 150nm were formed on the film surfaces.Such micro/nano structures cooperatively enhanced the hydrophobicity of the surface.The synthesized films exhibited a superhydrophobic property and the measured water contact angle reached 155.7° after the films were modified with octyltrimethoxysilane.
