Superhydrophobic surfaces that exhibit anti-sticking, anti-icing, and self-cleaning. A simple and inexpensive fabrication process is required to fabricate applicable superhydrophobic surfaces. In this study, we developed a facile fabrication method of superhydrophobic surfaces through ion beam irradiation with argon and oxygen gases. The ion beam irradiation method was empolyed to gain insight into the irradiation effect on the surface morphologies and surface properties of the substrates. After the ion beam irradiation, the surface morphology was changed to have microstructures with various surface roughness and form. The as-prepared structured surfaces shows an excellent superhydrophobic property with a high static contact angle (greater than 150 ⁰), which was ascribed to the synergistic effect of low- surface energy materials. As indicated by the results, improving the surface hydrophobicity may be an effective way of overcoming surface problem
