Oil-Fouling-Resistant PES Membrane

Tween 80-modified antifouling

Preferential adsorption of Tween 80 on the membrane surface forms an isolation layer that resists oil aggregation via demulsification and steric hindrance, effectively mitigating membrane fouling during oil-in-water emulsion separation.
