Partial substitution of the asymmetric 3,3',4,4'-biphenyl dianhydride monomer (aBPDA) into the backbone of a 6FDA-BPDA-DAM (6FDA=4,4'-hexafluoroisopropylidene, DAM=diaminomesitylene) diphthalic anhydride-based copolyimide based on symmetrical BPDA (s

Glassy 6FDA-based polyimides are attractive membrane materials for many industrially important gas separations; however, plasticization in aggressive natural gas often causes significant loss in CO2/CH4 selectivity. In this study, a family of thermal

Membranes are attractive for upgrading natural gas; however, the gas permeation processes through membranes are challenging to control. The coexistence of condensable H2S and CO2 typically causes membrane performance to decline under practical feed c
