Abstract

See full text

A method for making a nanoporous membrane is disclosed. The method provides a composite film comprising a two-dimensional material layer and a polymer layer, and then bombarding the composite film with energetic particles to form a plurality of pores through at least the two-dimensional material layer. The nanoporous membrane also has a two-dimensional material layer with a plurality of apertures therethrough and a polymer film layer adjacent one side of the graphene layer. The polymer film layer has a plurality of enlarged pores therethrough, which are aligned with the plurality of apertures. All of the enlarged pores may be concentrically aligned with all the apertures. In one embodiment the two-dimensional material layer is graphene.
