Title:
METHOD FOR PRODUCING DN GEL MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2017/209064
Kind Code:
A1
Abstract:
A method for producing a DN gel membrane, which comprises: a step (1) wherein a solution containing an ionic liquid B and an ionic liquid A that is composed of a first monomer having a polymerizable functional group is cast on a substrate and the first monomer is polymerized, thereby producing a first gel membrane; and a step (2) wherein the first gel membrane is immersed in a solution containing a second monomer that is different from the first monomer and the second monomer is polymerized, thereby producing a DN gel membrane. This method for producing a DN gel membrane enables continuous production that is suitable for industrial mass production of a DN gel membrane or an acidic gas separation membrane.
