POLYIMIDE-POLY(ETHYLENE GLYCOL) COPOLYMER MEMBRANE FOR SEPARATING CARBON DIOXIDE AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to a a polyimide-polyethylene glycol copolymer membrane for carbon dioxide separation and a manufacturing method thereof. The polyimide-polyethylene glycol copolymer membrane, which is used for carbon dioxide separation, is formed through introducing a polyethylene glycol to a polyimide including diamine including durene groups and 6FDA (2,2-bis-(3,4-dicarboxylic phenyl)-hexafluoro propane dianhydride.) Accordingly, the polyimide-polyethylene glycol copolymer membrane is prepared by using the polyimide-polyethylene glycol copolymers produced by introducing the polyethylene glycol to the polyimide which includes diamine including durene groups and 6FDA.
