Self-roughened superhydrophobic coatings for continuous oil–water separation

Hydrophobic polydimethylsiloxane based coatings were self-roughened on poly(ethylene terephthalate) textiles via a nonsolvent-induced phase separation method to fabricate superhydrophobic and superoleophilic surfaces. The method is simple and large-area scalable and the obtained textiles could be used as excellent filters for continuous oil–water separation.
