Effects of different surfactant properties on anti-wetting behaviours of an omniphobic membrane in membrane distillation

Surfactant-induced membrane wetting remains a severe challenge for MD membranes, even for omniphobic membranes. The anti-wetting characteristic of the omniphobic membrane engendered by surfactant-contained feed solutions have not been systematically studied. In this work, a robust omniphobic membrane #PVDF-F with a super liquid-repellent property was developed. It involved constructing a fluorinated re-entrant structure on a dopamine-coated …
