The development of high performance materials for carbon dioxide separation and capture will significantly contribute to a solution of global warming and natural gas purification. Polymer membrane-based gas separation has attracted recent interest due to their ease of operation, low operational cost and compactness in module preparation. The gas separation performance of most of the current polymers, however, does not meet the requirements of highly efficient separation for the industrial applications. We report herein, crosslinked norbonene copolymers having both PEG-and PDMS-units as highly CO2-soluble and permeable groups, respectively by in-situ ROMP polymerization as novel CO2 separation membranes. A series of crosslinked copolymers were prepared by tunning the ratio between PEG and PDMS units, and their properties including gas separation performance will be discussed in details. |
