Ultralight free-standing reduced graphene oxide membranes for oil-in-water emulsion separation

Abstract

We report a facile and environmentally friendly route to fabricate ultralight free-standing RGO membranes. Such membranes are capable of separating multiple types of surfactant stabilized oil-in-water emulsions with oil droplets of nano/sub-micrometer size, as well as display high separation efficiency and excellent anti-fouling properties, making them highlighted alternatives for water remediation.
