NOVELTY - Fabricating membrane involves contacting a porous substrate containing surface pores with dimensions of 2 microns with a liquid or coating to fill or coat the surface pores of the porous substrate, depositing a 2-D-material-flake solution on the porous substrate with the liquid-filled or coated surface pores to form a 2-D-material-flake-solution layer with a thickness of 40 microns, and evaporating solvent from the 2-D-material-flake-solution layer to form a selective-transport layer on the porous substrate with the liquid-filled or coated surface pores. USE - Method for fabricating membrane that is used for a variety of moisture transfer applications, including building wraps, solvent dehydration, fuel-cell feed humidification, and HVAC-system air humidification/dehumidification. ADVANTAGE - The membrane is highly permeable, composite-structured, vapor-transport membrane. The membrane has a thin selective transport layer located directly upon a low-cost, and macroporous substrate. The membranes do not employ a microporous or nanofibrous support layer, thus eliminating micropore-support vapor transport resistance and reducing membrane-production costs. The membrane provides high water-vapor-transport rates and very-low leak rates. The method is beneficial in humidification and dehumidification applications, where increased permeation rates can improve device efficiency, and reduce device size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a membrane for fluid-species transport, which comprises a porous substrate that defines surface pores with dimensions of 2 microns, and a selective-transport layer comprising 2-D-material flakes and coating the porous substrate and spanning across the surface pores.
