Abstract: Due to concerns for energy security and global warming, energy sustainability and carbon capture have attracted huge amount of interests. Capturing carbon dioxide can purify hydrogen and natural gas streams for energy generation and reduce the amount of emission to the environment. Membrane separation possesses competitive advantages like higher energy efficiency, smaller footprint, simplicity and environmental friendliness, compared to other separation technologies. Polymeric membranes are potential materials for fabricating gas separation membranes due to its low cost and ease of processability. The tradeoff between permeability and selectivity and its poor plasticization resistance to carbon dioxide have restricted its broad applications. In my study, modifications of poly(ethylene oxide) with a cross-linkable unit and polyimide with thermally labile units followed by post-treatment are employed to fabricate mechanically strong membranes with enhanced performance and stability for separation of carbon dioxide from light gases.
