英文摘要 | Mixed matrix membranes (MMMs) are highly promising for natural gas sweetening due to their high microporosity and outstanding gas separation performance. However, MMMs are frequently challenged by the polymer/filler interfacial incompatibility, leading to the deterioration of gas separation performance. In this study, the mixed-linker ZIF-7-8 was employed as a filler by finely tuning the molecular sieving for CO2/CH4 separation. An amino-functionalized ionic liquid ([C(3)NH(2)Mim][Cl]) was introduced for constructing the interface connection between the ZIF-7-8 filler and polymer matrix through coordination and hydrogen bonding, which was verified by extended X-ray absorption fine structure (EXAFS) and electron paramagnetic resonance (EPR). The design of interface interaction through an IL is crucial to improve the interface compatibility and the CO2/CH4 separation performance. The newly developed 20% ZIF-7-8-IL (1%)/PI and 25% ZIF-7-8-IL (1%)/PI MMMs displayed a dramatic improvement of CO2 permeability by 244.2% and 291.6%, from 308 to 1060 and 1206 barrer, respectively, for pure-gas separation, compared to the pristine polyimide matrix. Moreover, the 25% ZIF-7-8-IL (1%)/PI MMM also demonstrated outstanding low-temperature mixed-gas CO2/CH4 separation performance in the temperature range of -45-35 degrees C, far beyond the 2018 mixed-gas CO2/CH4 upper bound. |
