Abstract: An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.

Abstract: A method for making a graphene membrane includes applying a suspension of graphene platelets in a fluid onto a porous substrate, and applying a pressure differential to force the fluid through the substrate to yield a filtered fluid while retaining the graphene platelets on the substrate. The graphene platelets and the substrate form the graphene membrane.

Abstract: A membrane includes a porous polymer substrate, and at least a first layer of graphene platelets supported by the substrate. The graphene platelets of the first layer include aminated graphene platelets. A method for making a membrane includes providing a porous polymer substrate, providing a first suspension of graphene platelets in a fluid, wherein the graphene platelets of the first suspension are aminated graphene platelets, and applying the first suspension to the substrate to deposit a layer of the aminated graphene platelets on the substrate.
