荷叶表面微观结构的探究及超疏水铜的制备和表征

Study on Microstructure of Lotus Leaf Surface and Preparation and Characterization of Super-Hydrophobic

采用光学显微镜和原子力显微镜对荷叶结构进行观测,了解荷叶的微观结构及超疏水的原因。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,制备了超疏水表面铜。利用低表面能氟硅烷修饰后,表面表现出超疏水特性,接触角均大于100°。

The structure of lotus leaf was observed by optical microscope and atomic force microscope(AFM),and the microstructure and superhydrophobic reason of lotus leaf were studied.A super-hydrophobic surface with different adhesion properties was prepared by simple and convenient method.The super-hydrophobic surface copper was prepared by controlling the corrosion time of ammonia on the copper surface.After modification with low surface energy fluorosilanes,the surface showed superhydrophobic properties with contact angles greater than 100°.
