Case Study

KAUST-7 as a Nanofiller for Mixed-Matrix Membranes in Gas Separation Applications

Chen K, et al. Journal of Membrane Science, 2022, 661, 120848.

Fluorinated metal-organic framework KAUST-7 has been utilized as a nanofiller to enhance the performance of mixed-matrix membranes (MMMs) for gas separation. By incorporating KAUST-7 into the polymer of intrinsic microporosity (PIM-1) via a solution-casting method, the resulting MMMs exhibit improved gas separation properties due to the unique porous structure and high thermal stability of the MOF. The fabrication process involves dispersing KAUST-7 in a polymer solution under sonication, followed by controlled casting and vacuum drying to ensure uniform filler distribution. The tunable loading of KAUST-7 (0-40 wt%) allows for optimization of the membrane's permeability and selectivity. The incorporation of KAUST-7 into PIM-1 significantly enhances gas transport properties by introducing additional microporosity and reducing chain packing density, making these MMMs promising candidates for high-performance gas separation applications.
