Soluble, microporous, Troger's Base copolyimides with tunable membrane performance for gas separatioSoluble, microporous, Troger's Base copolyimides with tunable membrane performance for gas separation Yongbing Zhuang, Jong Geun Seong, Yu Seong Do, Won Hee Lee, Moon Joo Lee, Zhaoliang Cui, Angel E. Lozano, Michael D. Guiver*, Young Moo Lee* AbstractA facile two-step synthesis beginning with commercial monomers to prepare copolyimides by Tröger's Base (TB) formation provides membranes for the first time with tunable gas transport relative to hydrogen separations, CO2 plasticization resistance, and good mechanical and thermal properties. |
