MEMBRANES COMPRISING GRAPHENE

A selective membrane, for example an ultrafiltration, nanofiltration or reverse osmosis membrane, has a layer comprising flakes of graphene, graphene oxide, reduced graphene oxide, or functionalized variations. The flakes may form a layer themselves, be embedded in the surface of a layer of another...

Zusammenfassung:A selective membrane, for example an ultrafiltration, nanofiltration or reverse osmosis membrane, has a layer comprising flakes of graphene, graphene oxide, reduced graphene oxide, or functionalized variations. The flakes may form a layer themselves, be embedded in the surface of a layer of another compound, or be dispersed in a layer of another compound. In some cases, the flakes functions as a selective membrane. In other cases, the flakes modify the properties of a membrane, for example by making the membrane more hydrophilic. In yet other cases, the flakes function as a bonding agent between layers of a membrane.
