Polymer membranes are critically important in addressing urgent global needs in the 21st century for energy efficient gas separations as well as reliable, sustainable, efficient access to clean energy and clean water. In the gas separation field, polymer membranes are now well established for air separation, hydrogen purification, and, increasingly, natural gas processing. We are working on new membranes based on so-called thermally-rearranged polymers, which have among the highest combinations of gas permeability and selectivity.
