Superhydrophobic nickel films constructed of micro-nano hierarchical structure were prepared on copper foil through one-step electrodeposition process with choline chloride as crystal modifier. The effects of electrodeposition parameters on surface morphology was observed by scanning electron microscopy (SEM). The results demonstrated that the hierarchical nickel films consist of alternate flower-like and leaf-like structure. Under the optimal parameters, the nickel film has a static contact angle of 162 ± 1°, exhibiting excellent superhydrophobic property without organic surface modification. The superhydrophobic properties of the superhydrophobic nickel surface was analyzing via SEM, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). In addition, the potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS) of the superhydrophobic films in 3.5 wt% NaCl solution demonstrates that the fabricated superhydrophobic films have superior corrosion resistance. Furthermore, the superhydrophobicity of films shows good self-recovery performance through atmospheric exposure.

以氯化胆碱为晶体改性剂，通过一步电沉积法在铜箔上制备了微纳米分层结构的超疏水镍膜。电沉积参数对表面形态的影响通过扫描电子显微镜（SEM）观察到。结果表明，分层镍膜由交替的花状和叶状结构组成。在最佳参数下，镍膜的静态接触角为162±1°，表现出优异的超疏水性能，而无需进行有机表面改性。通过SEM，X射线衍射（XRD）和X射线光电子能谱（XPS）分析了超疏水镍表面的超疏水性能。此外，3.5％（重量）NaCl溶液中超疏水膜的电位动力学极化曲线和电化学阻抗谱（EIS）表明，所制备的超疏水膜具有优异的耐蚀性。此外，膜的超疏水性通过暴露于大气显示出良好的自我恢复性能。
