Wettability Transition of Nickel Films with Micro-Nano Cones Array

摘要：

　　An intelligent surface with Ni micro-nano cones array (MCA) was fabricated with electro-deposition method and exhibited super-hydrophilic nature when freshly prepared.Spontaneous transition from super-hydrophilicity to superhydrophobicity was observed when the surface was exposed in air at room temperature.The special surface structure of MCA played an important role in amplifying the surface wettability.Since the surface structure remained the same as the freshly prepared Ni MCA films during the storage,the transition was proved to be attributed to the change of surface chemical composition.Such wettability transition property of Ni MCA films is expected to be applied in the practical industry.
