摘要
先用二次阳极氧化法在纯铝表面制备出多孔阳极氧化铝(AAO)膜,再通过交流电沉积法在膜孔内沉积铜纳米线,制备出载铜AAO膜。然后用氢氧化钠溶液腐蚀除去部分AAO模板,裸露出的铜纳米线在其表面构造出柱状纳米粗糙结构,最后经过月桂酸乙醇溶液浸泡(低表面能修饰)。烘干后该表面与水滴的接触角为153.8°,滚动角小于1°,表现出超疏水性。
A porous anodic aluminum oxide（AAO） template was prepared by two-step anodic oxidation method on pure aluminum. Copper nanowires were then electrodeposited into the pores of AAO template by alternating current method, thus obtaining Cu-loaded AAO template. Part of the AAO template was removed by etching in a sodium hydroxide solution, and the exposed copper nanowires constructed a rough nanorod structure on the surface. This surface shows superhydrophobicity with a water contact angle of 153.8° and a sliding angle less than 1° after low-surface-energy modification by immersing in lauric acid–ethanol solution and drying.
