Document Type and Number:
WIPO Patent Application WO/2021/153515
Kind Code:
A1
Abstract:
This method for producing a gas separation membrane comprises: a step wherein a dispersion liquid, which is obtained by mixing graphene oxide and a zeolite microcrystalline body formed of MFI zeolite with pure water, is left at rest so that the periphery of the zeolite microcrystalline body is covered by the graphene oxide; a step wherein the dispersion liquid after being left at rest is dried and powderized; a step wherein the powder is subjected to a reduction treatment of the graphene oxide by means of heating; and a step wherein the powder after the reduction treatment is subjected to press molding so as to be formed into the shape of a membrane.
