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.
