▎ 摘  要

NOVELTY - Membrane (100) comprises a porous support (120), a composite (110) coated on the porous support comprising a crosslinked graphene oxide compound, where the crosslinked graphene oxide compound is a product of reacting a mixture comprising a graphene oxide compound and a crosslinker comprising a lignin. The membrane has high moisture permeability and low gas permeability. USE - Membrane for dehydrating of a gas. ADVANTAGE - The membrane provides a durable dehydration system that can be selectively permeable to water vapor, and less permeable to other gases. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for dehydrating a gas, which involves utilizing a membrane having a first side and a second side and introducing a first gas containing water vapor to a first side of the membrane, where the water vapor pressure on the first side of the membrane is higher than the water vapor pressure on the second side of the membrane and water vapor from the first gas passes through the membrane from the first side to the second side and the retained gas is retained on the first side of the membrane to generate a second gas and second gas has a lower water vapor pressure than the first gas. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a membrane. Membrane (100) Composite (110) Porous support (120)
