【摘要】 本文通过定向电结晶法制备了具有的超疏水性能的镍薄膜。扫描电子显微(SEM)研究发现,该薄膜产生超疏水(水滴接触角大于150°)性能的原因在于其表面呈微纳米分级结构。通过调节电沉积的电流密度和沉积时间,可以控制表面微纳米结构的尺寸,实现使沉积的镍薄膜润湿性从相对亲水(接触角88°)到超疏水(接触角154°)的转变。该超疏水镍薄膜制备方法简易,成本低廉,且无需化学修饰,有望在实际的电子工业中获得应用。更多还原

【Abstract】 Super-hydrophobic Nickel films were prepared by a simple and low cost electrodeposition method.The surface morphologies of the films characterized by scanning electronic microscope exhibit hierarchical structure with micro-nano cones array,which can be responsible for their super-hydrophobic characteristic(water contact angle over 150°) without any chemical modification.The wettability of the film can be varied from super-hydrophobic(water contact angle 154°) to relatively hydrophilic (water contact angle 87°) by controlling the size of the micro-nano cones.The mechanism of the hydrophobic characteristic of nickel films with this unique structure was illustrated by several models.Such micro-nanostructure and its special wettability are expected to be applied in the practical industry.更多还原
