| 摘 要： | 采用两步法制备了超疏水性ZnO纳米棒薄膜，在用磁控溅射在普通玻璃衬底上生长一层ZnO籽晶层基础上，利用液相法制备了空间取向高度一致的ZnO纳米棒阵列，经修饰后由亲水性转变为超疏水性.用扫描电子显微镜观察了纳米棒的表面结构，用接触角测量仪测出水滴在ZnO纳米棒薄膜表面的接触角为151°±05°，滚动角为7°.用Cassie模型对ZnO纳米棒薄膜的超疏水性进行了验证.关键词：ZnO纳米棒超疏水两步法

| Abstract: | Well-aligned ZnO nanorod array films (ZnO-NAFs) were coatedon common glass substrate by two-step method. A thin buffer layer of ZnO seeds were first deposited via RF magnetron sputtering,the ZnO-NAFS were then grown in a simple aqueous solution. We report a surface-modification induced hydrophilicity to superhydrophobicity transiton on ZnO-NAFs. The sample was characterized by scanning electron microscopy (SEM). The surfaces of ZnO-NAFs was superhydrophobic with a three-phase contact angle of 151°±0.5°, while the sliding angle is 7°. The superhydrophobicity of ZnO-NAFs was validated by Cassie's model. |
