| 英文摘要 | The wettability of solid surfaces, governed by both the chemical composition and the geometrical microstructure of the surface, is a very important property. It is reported that the hydrophobicity of a surface can be enhanced by the nano-structures or micro-structures because air that is trapped between the droplet and the solid surface minimizes the contact area. However, few studies involving the relationship between the hydrophobicity of a surface and the micro- and nano-structures have been reported. Herein, we prepared some micro- and nano-structures with a simple method, the influence of the structures on the hydrophobicity of the surface was given. Some micro- and nano-structures were constructed by etching the porous alumina membrane with NaOH solution. Then, the surfaces of smooth alumina, porous alumina membrane and the micro-and nanostructures were modified with fluoroalkylsilane(FAS-17). The wettability of the modified surfaces were studied by contact angle method and their morphology were characterized by scanning electron microscopy (SEM). The contact angle for water of the micro-and nanostructured surface(149degrees+/-2degrees) was much higher than that of the nano-structured surface (141degrees+/-2degrees) and the smooth surface(101degrees+/-1degrees). It was indicated that the micro-and nano-structure surfaces showed a more excellent property in improving the hydrophobicity than that of the other structured surfaces. The result of XPS analysis was also reported. |
