▎ 摘　　要

NOVELTY - The membrane (8) has graphene compounds provided in a porous matrix layer. The graphene compounds are dispersed in polymer in the porous matrix layer, where the polymer is formed by interfacial polymerization. The graphene compounds are functionalized with amine or carbonyl chloride groups and polyethylene glycol. An intermediate dense layer is provided between the porous matrix layer and a graphene compounds layer. The graphene compounds in the porous matrix layer increase rejection of the porous matrix layer. USE - Filtering or solid-liquid separation membrane. Uses include but are not limited to reverse osmosis membrane, nanofiltration membrane, ultrafiltration membrane and microfiltration membrane. ADVANTAGE - The membrane is designed such that a thin hydrophilic separation layer with pore size controlled by weight of flakes applied per unit area provides improved salt rejection at low pressure. The membrane has increased permeability or reduced energy consumption. The flakes make the membrane as hydrophilic, enhance flux and reduce membrane compaction. The membrane is designed such that liquid or organic solvent with high surface tension prevents re-aggregation of the flakes. The membrane comprises a top coat preventing the graphene compounds from washing or leaching out of the membrane. DETAILED DESCRIPTION - The graphene compounds are selected from a group consisting of graphene, functionalized graphene, graphene oxide, functionalized graphene oxide, reduced graphene oxide and functionalized reduced graphene oxide. An INDEPENDENT CLAIM is also included for a method for making a membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a membrane comprising a supporting membrane layer and a barrier membrane layer with a surface of the supporting membrane layer and a barrier membrane layer with an embedded graphene compound.
