▎ 摘　　要

NOVELTY - Formation of graphene membrane (100) involves applying a suspension of graphene platelets (104) in a fluid onto a porous substrate (108), and applying a pressure differential to force the fluid through the substrate to yield a filtered fluid when retaining the graphene platelets on the substrate. The graphene platelets and the substrate form the graphene membrane. USE - Formation of graphene membrane used for purifying water and conductive surface (all claimed) in batteries and filters. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the membrane. Membrane (100) Stack (102) Graphene platelet (104) Substrate (108)
