| 摘 要： | 采用简单便捷的方法制备出了具有不同黏附性能的超疏水表面. 通过控制氨气对金属铜表面的腐蚀时间, 分别制备了具有微米球及微米棒状结构的表面. 利用低表面能氟硅烷(FAS)修饰后, 2种表面均表现出超疏水特性(接触角均大于150°), 然而其黏附性能却截然相反. 具有微球结构的表面呈现出高黏附特性, 而具有微米棒状结构的表面则显示出低黏附特性. 研究发现, 表面不同的微观结构导致了液滴在其表面上分别处于Cassie-impregnating wetting态及Cassie态, 从而呈现出了不同的黏附性能.

| Abstract: | In this paper, we report a novel ammonia corrosion strategy for preparation of the super-hydrophobic copper surface with controlled adhesion. Surfaces with ball-like structure or rod-like structure can be achieved by simply changing the corrosion time. After modification by the low surface energy material fluoroalkylsilane(FAS), both the two surfaces show super-hydrophobic property, but the adhesive properties are rather different, the surface with ball-like structure shows high adhesion and the surface with rod-like structure shows low adhesion. The difference is ascribed to the different wetting states: Cassie-impregnating wetting state and Cassie state for droplets on the surface resulted from the different microstructures. |
