Title:
SEPARATION MEMBRANE, SEPARATION MEMBRANE PRODUCTION METHOD, AND COATING FLUID FOR PRODUCING SEPARATION MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/059368
Kind Code:
A1
Abstract:
The present invention provides a separation membrane having high separation from a gas mixture including an acid gas. This separation membrane 10 comprises a separation functional layer 1 including graphene oxide, an ionic liquid, and a polymer. The ionic liquid is hydrophilic, for example, and includes imidazolium ions and tetrafluoroborate. This separation membrane 10 production method includes: coating a coating fluid that includes a graphene oxide, ionic liquid, and a polymer, on to a base material; obtaining a coating membrane; and drying the coating membrane.
