Summary: The ultrapermeable benzotriptycene-based polymer PIM-TMN-Trip shows high permeability and CO2/CH4 selectivity, close to the 2019 Robeson upper bound. Upon continuous exposure to CO2, there is an increase in selectivity due to a decrease in CH4 permeability, suggesting a rearrangement of free volume instead of a reduction. Mixed gas permeability experiments with high stage-cut confirm the potential of PIM-TMN-Trip membranes for biogas upgrading.
