The vast majority of the world’s energy is presently derived from the burning of fossil fuels, which releases vast quantities of carbon dioxide (CO2) into the environment and results in undesirable climate change. Practical and cost efficient methods of CO2 separation and capture would thus solve one of the most challenging problems facing humanity today. This presentation summarizes our effort on the development of novel polymer membranes for high flux CO2 separation and the investigation of the fundamental understanding in its molecular transport through the polymer membranes. Our strategy focuses on tuning solubility selectivity in addition to diffusion selectivity for achieving high permeability membranes combined with good selectivity. Various synthetic techniques including ROMP and post functionalization were used and the careful design permits to prepare well-defined novel high permeable polymers containing CO2-philic groups. The structure-property relationships including CO2 uptake, CO2 and N2 permeability, CO2/N2 selectivity to the polymer structure will be discussed.
