The superhydrophobic property attracts many researchers in the both field of academe and industry. All of the superhydrophobic materials have the rough surface structure based on the Cassie-Baxter equation. The trapping of air into the rough surface structure caused the improvement of the superhydrophobic property. Therefore, the nanostructure control technique is very important. Of course, considering application in industry, the process cost of the superhydrophobic materials is very important. In this work, the superhydrophobic film is fabricated by the hot water treatment, which is one of the chemical bath deposition methods, of the metal aluminum. The hot water process of spattered Al film on the glass substrate results in the fabrication of the high transparent superhydrophilic film constructed by perpendicular nanosheet structure. After fluoroalkylsilanes coating, the resultant film shows the high transparent superhydrophobic property. Moreover, these processes can be applied to the commercial Al foil. So, we can easily obtain superhydrophobic film by using the hot water process.
