What is it about?

UV irradiation was utilized to modify both the structure and composition of graphene oxide flakes in aqueous media.

Why is it important?

The UV-treated graphene oxide flakes can be fabricated into membranes and realize antifouling properties in oil/water separation.

Tuning the underwater oleophobicity of graphene oxide coatings via UV irradiation
Ultraviolet (UV) irradiation was utilized to gradually modify the chemistry and structure of graphene oxide (GO) flakes, as confirmed by XPS and AFM. Ultrathin GO coatings/membranes, made of UV-irradiated flakes, showed tunable underwater oleophobicity. UV-treated, superoleophobic GO membranes exhibited excellent antifouling capability for oil/water separation.
