This research investigated the fabrication of pillar-type nickel nanostructures by using an electrodeposition solution containing NaCl. When nickel electrodeposition was performed using the NaCl-containing electrodeposition solution, the growth of the electrodeposition structure in the (200) crystal direction was restricted, whereas that in the (111) crystal direction was promoted. Accordingly, when electrodeposition was performed using the NaCl-containing electrodeposition solution, an anisotropic, pillar-shaped electrodeposition structure was formed. A sharper pillar structure was formed with increasing concentration of NaCl added to the electrodeposition solution. Additionally, it was confirmed that a specimen manufactured using electrodeposition solution containing NaCl of 2 M or higher had a superhydrophobic surface after surface treatment.
