Three new isomeric 6FDA-based polyimide-ionenes, with imidazolium moieties and varying regiochemistry ( para-, meta-, and ortho- connectivity), and composites with three different ionic liquids (ILs) have been developed as gas separation membranes. The structural-property relationships and gas separation behaviors of the newly developed 6FDA polyimide-ionene + IL composites have been extensively studied. All the 6FDA-based polyimide-ionenes exhibited good compatibility with the ILs and produced homogeneous hybrid membranes with the high thermal stability of ~380 °C. Particularly, [6FDA I4A pXy][Tf 2 N] ionene + IL hybrids having [C 4 mim][Tf 2 N] and [Bnmim][Tf 2 N] ILs offered mechanically stable matrixes with high CO 2 affinity. The permeability of CO 2 was increased by factors of 2 and 3 for C 4 mim and Bnmim hybrids (2.15 to 6.32 barrers), respectively, compared to the neat [6FDA I4A pXy][Tf 2 N] without sacrificing their permselectivity for CO 2 /CH 4 and CO 2 /N 2 gas pairs.
