| 摘 要： | 通过电镀方法在铜基体表面制备出了粗糙镍表面,SEM照片显示镍层呈现纳米针状结构,接触角测试表明水在其表面接触角约为112°,调节电镀时间,增大纳米针尺寸并不能实现超疏水性.在针状镍表面继续施加化学镀,对微结构进行修饰,SEM照片显示当化学镀达到1min时,纳米针尖被球冠状结构所代替,水在表面接触角增至152.3°,这表明镍表面成功地从疏水性转变成了超疏水性.

| Abstract: | Superhydrophobic nickel films were prepared by electrodeposition and electroless deposition without chemical modification.Experimental results reveal that the nickel film fabricated by electrodeposition is characterized with nanocone arrays and only has a contact angle of about 112°.By coupling electroless deposition,as the second step,hemispherically topped nanocones are generated when electroless deposition time amounts 1min and a high contact angle as much as 152.3° is obtained;nickel surface has successfully transformed from hydrophobic to superhydrophobic. |
