Introducing the amino acid ionic liquids (AAILs) into polymeric membranes, have been a promising way to improve CO₂ permeation-separation performance. A series of novel mixed matrix membranes (MMMs), based on Pebax 2533 and the AAILs@polymers of intrinsic microporosity (core-shell) composite nanoparticles (AAILs@PIM (core-shell) CNPs), were prepared. The composite nanoparticle was composed of the PIM as the dense shell and the AAILs as the core. The AAILs as the core provided high CO₂ adsorption selectivity; and the AAILs covered by nanospheres avoided its loss. Moreover, the PIM shell and Pebax matrix also provided a good organic-organic interface in the MMMs. The chemical characterization of AAILs@PIM (core-shell) CNPs was performed by Fourier transform infrared spectroscopy. The morphology and structure of AAILs@PIM (core-shell) CNPs was investigated by transmission electron microscopy. The effect of incorporating the PIM HNPs on the chain segments of Pebax matrix was investigated by the differential scanning calorimeter. Gas transport property of the (AAILs@PIM (core-shell) CNPs)/Pebax MMMs was reported. Compared with the original Pebax membrane, the (AAILs@PIM (core-shell) CNPs)/Pebax MMMs displayed higher CO₂/N₂ selectivity at the cost of a reduction in CO₂ permeability because of the hydrogen bond of the AAILs-CO₂ complexes. It is also found that increasing the temperature can eliminate the hydrogen bond of the AAILs-CO₂ complexes. Therefore, at high temperature, the (AAILs@PIM (core-shell) CNPs)/Pebax MMMs exhibit both higher CO₂ permeability and higher CO₂/N₂ selectivity than the original Pebax membrane has. The outstanding CO₂ permeation-separation performance shows great potential application to the flue gas treatment.

将氨基酸离子液体（AAIL）引入聚合物膜中，已成为改善CO ₂渗透分离性能的一种有前途的方法。制备了一系列基于Pebax 2533和内在微孔性（核-壳）复合纳米粒子（AAILs @ PIM（核-壳）CNP）的AAILs @聚合物的新型混合基质膜（MMM）。复合纳米颗粒由PIM作为致密壳和AAILs作为核组成。以AAIL为核心的CO ₂高吸附选择性 纳米球覆盖的AAIL避免了其损失。而且，PIM外壳和Pebax基质在MMM中也提供了良好的有机-有机界面。AAILs @ PIM（核-壳）CNP的化学表征通过傅里叶变换红外光谱进行。通过透射电子显微镜研究了AAILs @ PIM（核-壳）CNP的形态和结构。通过差示扫描量热仪研究了将PIM HNP掺入Pebax基质链段上的作用。据报道（AAILs @ PIM（核-壳）CNP）/ Pebax MMM的气体传输特性。与原始Pebax膜相比，（AAILs @ PIM（核-壳）CNPs / Pebax MMMs显示出更高的CO ₂ / N ₂选择性，但降低了CO的成本₂因为AAILs-CO的氢键的渗透性₂络合物。还发现提高温度可以消除AAILs-CO ₂络合物的氢键。因此，在高温下，（AAILs @ PIM（核-壳）CNPs）/ Pebax MMMs比原始Pebax膜具有更高的CO ₂渗透性和更高的CO ₂ / N ₂选择性。出色的CO ₂渗透分离性能显示了在烟气处理中的巨大潜力。
