Abstract: To meet the demands of extensive application of metal superhydrophobic surface, the superhydrophobic surface was prepared by the way that the zinc substrate was immersed perpendicularly into stannous chloride (SnCl₂) acetone solution and followed hydrophobization by n-octadecanethiol acetone solution. The prepared samples were characterized by powder X-ray diffraction analysis (XRD), and scanning electron microscopy (SEM). The results show that the surface superhydrophobicity is composed of micro-nano binary structures and the prepared surface has a high water contact angle (CA) of 158° and a small sliding angle (SA) of less than 5°.
