| 摘 要： | 采用阴离子表面活性剂十二烷基苯磺酸钠(SDBS)作为辅助刻蚀剂, 利用盐酸刻蚀, 在铝基质的表面形成了纳米-微米混合的粗糙结构; 化学刻蚀后的粗糙表面经过1H,1H,2H,2H-全氟癸烷基三乙氧基硅烷(FDTES)的修饰, 形成了接触角大于160°的超疏水表面. 扫描电镜表征结果显示, 所得到的超疏水表面具有纳米-微米混合结构; 基于此, 利用气泡辅助刻蚀机理初步解释了二级混合结构产生的原因, 认为是坑刻蚀和位错刻蚀的共同作用导致了混合结构的产生. 此外, 不同pH和长时间暴露实验证明所制备的铝基超疏水表面具有良好的稳定性.

| Abstract: | The SDBS/HCl mixed solution was used to etch aluminum surface, and some nano-micro mixed structures were appeared on the surface. After modified by 1H,1H,2H,2H-perfluorodecyltriethoxysilane(FDTES), the aluminum surface was reached superhydrophobility, and the water contact angle was more than 160°. The SEM experimental results showed that the aluminum superhydrophobic surface was of nano-micro mixed structure. According to the phenomenon, the bubble assisted etching mechanism(pit-etching and dislocation etching) was used to primarily explain the cause of the two-step mixed structures. Moreover, the experiments of different pH and different exposure time showed the aluminum superhydrophobic was very stable. |
