Superhydrophobicity means that a water contact angle is greater than 150°, and many materials and manufacturing techniques have been conducted for superhydrophobic surfaces. Methods for making superhydrophobic surfaces include lithography, electroplating, chemical etching, spray coating, but they have environmental issues and process complexity. Electrospinning is a process of making superhydrophobic surfaces, which is fast and simple method, and a large amount of nanostructures can be made with a small amount of polymer solution. In this study, nanostructures were created through electrospinning and electrospraying of PET(Polyethylene Terephthalate), and superhydrophobic surfaces were successfully manufactured. It is meaningful that waste PET was used as an electrospinning solution and no additional process was required for superhydrophobic implementation. The fabricated PET membrane’s water contact angle was confirmed about 151°, and this technology can be used for hydrophobic films, electronics such as solar panels, and building windows.
