▎ 摘  要

NOVELTY - Phenolic-graphene oxide composition comprises phenolic-graphene oxide having a carbon to oxygen (C:O) ratio of 2.1-5. USE - The composition is useful in a membrane separation process (claimed). ADVANTAGE - None given. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: liquid crystalline phenolic-graphene oxide composition comprising discotic phenolic-graphene oxide particles having a carbon to oxygen ratio of 2.1-5; forming (M1) a liquid crystalline phenolic-graphene oxide composition comprising providing a liquid phase reaction mixture comprising a phenolic compound and discotic graphene oxide particles, and facilitating a reaction between the phenolic compound and the discotic graphene oxide particles for a time to form a composition comprising discotic phenolic-graphene oxide particles having a carbon to oxygen ratio of 2.1-5; phenolic-graphene oxide film comprising a laminar arrangement of phenolic-graphene oxide having a C:O ratio of 2.1-5; eparation membrane comprising a membrane layer formed from a phenolic-graphene oxide film; forming (M2) a phenolic-graphene oxide membrane comprising solution casting a liquid crystalline phenolic-graphene oxide composition onto a surface to form the phenolic-graphene oxide membrane; and forming (M3) a phenolic-graphene oxide membrane comprising contacting a graphene oxide film or membrane with a phenolic compound, and facilitating a reaction between the phenolic compound and the graphene oxide for a time to form a phenol-graphene oxide film or membrane in which the phenolic-graphene oxide has a carbon to oxygen ratio of 2.1-5.
