title: Fabrication of superhydrophobic cotton textiles for water-oil separation based on drop-coating route.
abstract: In the present study, we are so excited to report a simple drop-coating method for fabricating the superhydrophobic cotton textiles which can remove the water in oil (or the oil in water). It is confirmed that the superhydrophobic composite thin film containing modified-ZnO nanoparticles and polystyren (PS) has been successfully fabricated on the cotton textiles surface by a single-step procedure, and the superhydrophobic cotton textiles displays an excellent property in water-oil separation which is rarely put forward and studied. The static water contact angle on the superhydrophobic cotton sample surface arranges from 153° to 155°, and stays almost the same after exposure to ambient air or immersion in the corrosive liquids and oil, indicating the considerable range of potential applications for the superhydrophobic cotton textiles fabricated by this simple method.
