Abstract: A method of forming a graphene oxide (GO) film on a substrate involves depositing a GO ink on a surface of a porous substrate, and mechanically removing excess ink on the surface of the porous substrate while simultaneously providing a pressure difference that forces a liquid medium of the ink through the porous substrate to provide a GO film on the surface of the porous substrate. The method provides GO membranes having similar water vapor permeance but significantly better selectivity to GO membranes produced by traditional blade casting methods and to GO membranes produced by traditional vacuum filtration methods.

Abstract: A large-area monolayer of solvent dispersed nanomaterials and method of producing same is provided. The method includes dripping a nanomaterial solvent into a container filled with water whereby the nanomaterial being dripped collects at the air-water interface to produce the large-area monolayer. In one embodiment, different nanomaterial solvents can be dripped, at predetermined intervals such that the resulting large-area monolayer includes at least two different nanomaterials.

Abstract: Embodiments of the present invention relate to energy storage devices and associated methods of manufacture. In one embodiment, an energy storage device comprises an electrolyte. An anode is at least partially exposed to the electrolyte. A selectively permeable membrane comprising a graphene-based material is positioned proximate to the anode. The selectively permeable membrane reduces a quantity of a component that is included in the electrolyte from contacting the anode and thereby reduces degradation of the anode.
