摘　　要：通过水热法在铜表面成功制备了一层具有纳米机构的超亲水薄膜,其表面的接触角可达到6°。随后用氟硅烷对其表面进行修饰,使表面由超亲水变成了超疏水,接触角达到了156°,滚动角小于10°。用扫描电镜、接触角测量仪、X射线衍射仪等技术对超疏水表面进行了表征和分析。X射线衍射分析表明,铜表面的片状结构为氧化铜。扫描电镜对铜表面形貌观察显示,温度、反应时间对表面的形貌影响比较大。片状结构之间的空隙和低表面的修饰是导致超疏水性能的主要原因。将铜超疏水表面放在不同高度的水底一段时间,取出后对其接触角进行测量,结果发现超疏水性能消失,接触角变小。We prepared a superhydriphilic film on copper by a facile hydrothermal method, the water contact an- gle was 6°. After modified with fluoride, the surface exhibits superhydrophobicity and the water contact angle can reach 156°, the sliding angle less than 10°. The result of the XRD patterns confirms that the nano-structure was cupric oxide. The SEM shows that the morphology rely on the temperature and reaction time. The airs a- mong the nano structures and the fluoride lead to the superhydrophobicity. When the film was put down the water with varies height, the superhydrophobicity was changed even to a superhydrophilicity. The reason of the change was discussed briefly.
