▎ 摘　　要

NOVELTY - A single-layer graphene-based membrane comprises graphene-polymer composite which consists of amine functionalized graphene and polymer containing anhydride group as linker for linking amine functionalized graphene to polymer. USE - A single-layer graphene-based membrane. ADVANTAGE - Membrane has increased wettability and reduced fouling effects. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) composition comprising graphene-polymer composite which consists of amine functionalized graphene and polymer containing anhydride group as linker for linking amine functionalized graphene to polymer; and (2) production of single-layer graphene-based membrane which involves reacting polymer containing anhydride group with amine functionalized graphene in presence of solvent to form intermediate product and thermal imidizing intermediate product to form graphene grafted polymer composite. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the chemical synthesis for preparing graphene grafted poly(acrylonitrile-co-maleimide).
