▎ 摘　　要

NOVELTY - The membrane has a graphene oxide coating layer formed with nano-porous carbon and mounted on a supporter i.e. porous polymer supporter. Thickness of the graphene oxide coating layer is in 1-50 nm. The porous polymer supporter is selected from polysulfone, polyethersulfone, polyimide, polyether amide, polyamide, polyacrylonitrile, cellulose acetate, cellulose triacetate and polyvinylidene fluoride. Pore size of the porous polymer supporter is in 10-500 nm range. The coating layer is provided with graphene oxide of monolayer and multi-layer. Size of graphene oxide is in 0.1-5 micro meter. USE - Graphene oxide nano-composite membrane for gas separation. ADVANTAGE - The membrane increases gas transmittance and selectivity, enhances selectivity of the hydrogen gas about the permeability of the hydrogen gas and carbon dioxide, easily performs hydrogen separation process, enhances connectivity between the graphene oxide coating layer and the supporter by reforming various supporters of surfaces and prevents graphene oxide coating layer from being easily exfoliated. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a gas separation graphene oxide nano-composite membrane manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a graphene oxide nano-composite membrane manufacturing method. '(Drawing includes non-English language text)'
