In this study, poly (ether-block-amide) (Pebax) facilitated transport membranes (FTMs) containing aniline, and ionic liquid (IL) modified alumina (M-Al) particles were prepared. Aniline molecules acted as semi-mobile carriers and IL-modified particles as fixed carriers for CO₂ molecules in these membranes. Different amounts of M-Al particles were added to the Pebax/aniline (50 wt%) membrane, and a facilitated transport membrane containing 5 wt% M-Al particles was obtained as the optimal membrane. For Pebax/aniline (50 wt%)/M-Al (5 wt%) membrane, CO₂ permeability was 167 barrer, and CO₂/N₂ selectivity was 123 increased by 94% and 168% compared to pure Pebax membrane, respectively. The CO₂ separation performance of the prepared FTMs was also evaluated in the humidified state. The results showed that in the presence of water, the amino groups in the structure of aniline and IL performed better and improved the facilitated transport mechanism. Therefore, for all FTMs, CO₂ permeability significantly increased in the humidified state so that CO₂ permeability and CO₂/N₂ selectivity reached 406 barrer and 123, respectively, for optimal membrane. The molecular simulation was used to study details of the motion of aniline molecules in the polymeric matrix. The simulation and experimental results confirmed each other and showed that the presence of aniline prevents the hopping mechanism from stopping even at low concentrations of particles as fixed carriers and creates a combined hopping-vehicle mechanism in the membrane structure that results in excellent performance membranes.

在这项研究中，制备了含有苯胺和离子液体 (IL) 改性氧化铝 (M-Al) 颗粒的聚（醚-嵌段-酰胺）（Pebax）促进传输膜（FTM）。苯胺分子作为半移动载体，IL 改性颗粒作为这些膜中CO ₂分子的固定载体。在Pebax/苯胺（50wt%）膜中加入不同量的M-Al颗粒，得到含有5wt%M-Al颗粒的促进传输膜作为最佳膜。对于 Pebax/苯胺 (50 wt%)/M-Al (5 wt%) 膜，与纯 Pebax 膜相比，CO ₂渗透率为 167 barrer，CO ₂ /N ₂选择性为 123，分别提高了 94% 和 168% . 二氧化碳₂在加湿状态下也评估了制备的 FTM 的分离性能。结果表明，在水的存在下，苯胺和IL结构中的氨基表现更好，并改善了易化转运机制。因此，对于所有 FTMs，在加湿状态下CO ₂渗透率显着增加，使得 CO ₂渗透率和 CO ₂ /N ₂对于最佳膜，选择性分别达到 406 barrer 和 123 barrer。分子模拟用于研究聚合物基体中苯胺分子运动的细节。模拟和实验结果相互证实，并表明苯胺的存在可以防止跳跃机制即使在低浓度的粒子作为固定载体时也不会停止，并在膜结构中创造了一种组合跳跃机制，从而产生了性能优异的膜。
