▎ 摘　　要

NOVELTY - Membrane comprises a support, and a composite comprising a graphene oxide compound and a polyvinyl alcohol, where the composite is coated on the support, and the membrane has a high moisture permeability and low gas permeability. USE - The membrane is used for dehydration of a gas, including non-polar or inert gas, preferably air, oxygen, nitrogen (all claimed), hydrogen, methane, propylene, carbon dioxide and natural gas. ADVANTAGE - The membrane has high moisture permeability and low gas permeability, and effectively dehydrates air or other desired gases or feed fluids. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method of dehydrating a first gas; and (2) a device for dehydrating a gas.
