Amphiphilic zeolitic imidazolate framework for improved CO2 separation in PIM-1 mixed matrix membranes

This study aims to enhance the compatibility between filler and polymer in mixed matrix membranes (MMMs), addressing an important challenge in membrane development. ZIF-94, known for its affinity to CO2, was partially modified with 2-undecylimidazolate (umIm) through the solvent-assisted ligand exch...

ZIF-94, known for its affinity to CO2, was partially modified with 2-undecylimidazolate (umIm) through the solvent-assisted ligand exchange (SALE) method to improve its compatibility with the prototypical polymer of intrinsic microporosity PIM-1. The modified ZIF-94 (ZIF-94-umIm) can be considered as an amphiphilic MOF with both hydrophilic and hydrophobic moieties, while maintaining a considerably high CO2 adsorption capacity (2.34 mmol g-1 at 90 kPa and 0 °C). Gas separation experiments were performed using mixed gas compositions of 15/85 CO2/N2 at 3 bar and 35 °C. The resulting MMM with a 5 wt.% loading exhibited an enhanced CO2 separation performance, with ca. 70% and 10% increases in CO2 permeability (8900 Barrer) and CO2/N2 selectivity (20.2), respectively, compared to pristine PIM-1 membranes. In addition, thin film nanocomposite membranes were prepared showing a 23.5 CO2/N2 selectivity at 2350 GPU of CO2. This modification strategy shows a great potential for improving the CO2 capture technologies, highlighting the potential of tailoring MOF fillers for advanced membrane materials in gas separation applications.This work acknowledges grants PID2022-138582OB-I00 (funded by MCIN/AEI/10.13039/501100011033/ and by “ERDF A way of making Europe”), TED2021-130621B-C4 (funded by MCIN/AEI/10.13039/501100011033/ and the European Union-NextGeneration EU), and CEX2023-001286-S (funded by MICIU/AEI /10.13039/501100011033).
