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.

The paper describes the separation of an oil–water emulsion by filtration using poly(ethylene terephthalate) track-etched membranes (PET TeMs) with regular pore geometry and narrow pore size distribution. PET TeMs were modified with trichloro(octyl)silane to increase their hydrophobic properties. Conditions for the modification of PET TeMs with trichloro(octyl)silane were investigated. The results of changes in the pore diameters and the contact angle depend on the concentration of trichloro(octyl)silane and the soaking time are presented. The obtained samples were characterized by FTIR, AFM, SEM-EDX and gas-permeability test. Chloroform–water and cetane–water emulsions have been used as a test liquid for oil–water separation.
