Self-roughened superhydrophobic coatings for continuous oil–water separation

Abstract

Hydrophobic polydimethylsiloxane based coatings were self-roughened on textiles via a nonsolvent-induced phase-separation method. The self-roughened coatings have superior durability in superhydrophobicity. The obtained superhydrophobic and superoleophilic materials were demonstrated as excellent filters for continuous oil–water separation. The work showed large-scale and practical application for consecutive collection of oil from water.
