Poly(amide‐6‐b‐ethylene oxide)(PEBA) mixed matrix membranes (MMMs) containing different metal‐organic frameworks (MOFs) of CuBTC, ZIF‐8, and ZIF‐67 have been dip‐coated on asymmetric PAN supports. To optimize the ideal skin‐layer parameters, MOF loadings of 5, 15, 25, and 35 wt% were applied. The synthesized MOFs and MMMs were structurally characterized using X‐ray diffraction (XRD), Fourier‐transform infrared (FTIR), and field emission scanning electron microscopy (FESEM). The average sizes of the synthesized ZIF‐8, ZIF‐67, and CuBTC have been determined about 100, 400, and 60–500 nm, respectively. Permeability tests of the MMMs performed using 12‐bar feed streams of pure CO₂, CH₄, and N₂, showed 200–338% enhancements of CO₂ permeability and up to a 43% increase in CO₂/CH₄ selectivity relative to the neat PEBA membrane. The membrane performances were also examined by the mixed gas feeds of CO₂:CH₄ (10:90). © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

不同MOF填料对负载型PEBA混合基质膜的CO2去除性能的比较

包含CuBTC，ZIF-8和ZIF-67不同金属有机骨架（MOF）的聚（酰胺-6- b-环氧乙烷）（PEBA）混合基质膜（MMM）已浸涂在不对称PAN载体上。为了优化理想的表层参数，应用了5、15、25和35 wt％的MOF含量。使用X射线衍射（XRD），傅立叶变换红外（FTIR）和场发射扫描电子显微镜（FESEM）对合成的MOF和MMM进行结构表征。合成的ZIF-8，ZIF-67和CuBTC的平均尺寸分​​别约为100、400和60-500 nm。使用纯净的CO ₂，CH ₄和N _2的12巴进料流对MMM进行的渗透性测试表明，CO的增加量为200–338％₂渗透性和最多增加43％的CO ₂ / CH ₄的选择性相对于所述整齐PEBA膜。还通过CO ₂ ∶CH ₄（10∶90）的混合气体进料检查膜性能。©2020年化学工业协会和John Wiley＆Sons，Ltd.
