Abstract
An article having a nanoporous membrane and a nanoporous graphene sheet layered on the nanoporous membrane with the nanoporous membrane and the nanoporous graphene sheet in direct contact. A method of: depositing a layer of a diblock copolymer onto a graphene sheet, etching a minor phase of the diblock copolymer and a portion of the graphene in contact with the minor phase to form a nanoporous article having a nanoporous graphene sheet and a nanoporous layer of a polymer, and removing the nanoporous layer of a polymer.
