제목 High-performance CO2/N2 separation membranes based on self-cross-linked PGP-POEM graft copolymer
초록 In this work, a high performance self-cross-linked membrane based on the poly(glycidyl methacrylate-g-poly-(propylene glycol))-co-poly(oxyethylene methacrylate) (PGP−POEM) graft copolymer is reported. The self-cross-linking ability of the PGP-POEM graft copolymer originates from the epoxide−amine click chemistry, which takes place under mild conditions without any additional cross-linking agents or catalysts. The self-cross-linking reaction occurred during the membrane drying process without thermal treatment at high temperature. The gas separation properties of the membranes were investigated as a function of POEM content in the copolymer. The PGP-POEM membranes showed the significant enhancement in both permeance and selectivity as the POEM content increased up to 51.2 wt %. The best performance of the membrane was close to the target area for commercialization of CO2 capture membranes, showing a CO2 permeance of 500 GPU and CO2/N2 selectivity of 22.4.
