▎ 摘　　要

NOVELTY - A membrane comprises support and composite comprising graphene oxide compound and sulfonated polymer, where the sulfonated polymer comprises sulfonated polyvinyl alcohol, sulfonated polyacrylic acid, sulfonated polyether ether ketone, sulfonated polystyrene, or combination, and the composite is coated on the support. USE - Membrane for dehydrating gas such as air, oxygen, nitrogen, hydrogen, methane, propylene, carbon dioxide, natural gas. ADVANTAGE - The membrane has high moisture permeability and low gas permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for dehydrating first gas, which involves applying a membrane to first gas.
