▎ 摘 要
NOVELTY - The method involves obtaining (S01) dispersion liquid by mixing graphene oxide and a zeolite microcrystalline structure formed of zeolite with pure water that is left at rest so that the periphery of the zeolite microcrystalline structure is covered by the graphene oxide. The dispersion liquid after being left at rest is dried (S03) and powderized. The powder is subjected (S04) to a reduction treatment of the graphene oxide by heating and the powder after the reduction treatment is subjected to press molding so as to be formed into the shape of a membrane. USE - Method for producing gas separation membrane (claimed). ADVANTAGE - The gas separation performance is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a gas separation membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for producing a gas separation membrane.
