Most examples of mixed-matrix membranes (MMMs) involve one type of polymer and one type of inorganic filler particle. Here, both polymer blending and MMM approaches are combined to form exceptional three-component membranes for CO₂/N₂ separation. Nano-sized amino-functionalized UiO-66 is added to a polymer blend of PIM-1 and an ether side chain functionalized polyphosphazene (MEEP80) to create a series of MMMs. Incorporation of UiO-66-NH₂ particles boosts the CO₂ permeability of the PIM-1/MEEP80 (75:25) blend from 3140 up to nearly 6000 Barrer, while maintaining its CO₂/N₂ selectivity within the range of 22–25, placing it well above the 2008 Robeson upper bound. In addition, the compatibility of the component parts leads to improved mechanical flexibility and mitigated physical aging for more than 300 days. This unique strategy constitutes a facile MMM formulation approach for energy efficient carbon capture from flue gas.

来自微孔聚合物共混物和具有出色的CO ₂ / N ₂分离性能的纳米级金属有机骨架的混合基质膜

混合基质膜（MMM）的大多数示例涉及一种类型的聚合物和一种类型的无机填料颗粒。在这里，将聚合物共混和MMM方法结合在一起以形成用于CO ₂ / N ₂分离的出色的三组分膜。将纳米尺寸的氨基官能化UiO-66添加到PIM-1和醚侧链官能化聚磷腈（MEEP80）的聚合物共混物中，以创建一系列MMM。掺入UiO-66-NH ₂颗粒可将PIM-1 / MEEP80（75:25）共混物的CO ₂渗透率从3140提高到近6000 Barrer，同时保持其CO ₂ / N ₂选择性在22–25范围内，使其远高于2008 Robeson上限。此外，组件之间的兼容性可改善机械柔韧性并减轻300天以上的物理老化。这种独特的策略构成了一种简便的MMM配方方法，用于从烟气中高效捕集碳。
