Synergistic Construction of Sub-Nanometer Channel Membranes through MOF–Polymer Composites: Strategies and Nanofiltration Applications

Polymers, Journal Year: 2024, Volume and Issue: 16(12), P. 1653 - 1653

Published: June 11, 2024

The selective separation of small molecules at the sub-nanometer scale has broad application prospects in field, such as energy, catalysis, and separation. Conventional polymeric membrane materials (e.g., nanofiltration membranes) for separations face challenges, inhomogeneous channel sizes unstable pore structures. Combining polymers with metal–organic frameworks (MOFs), which possess uniform intrinsic structures, may overcome this limitation. This combination resulted three distinct types membranes: MOF polycrystalline membranes, mixed-matrix membranes (MMMs), thin-film nanocomposite (TFN) membranes. However, their effectiveness is hindered by limited regulation surface properties growth MOFs poor interfacial compatibility. main issues preparing are uncontrollable adhesion between substrate. Here, could serve a simple precise tool regulating functionalities while enhancing to For primary challenge compatibility MOFs. Strategies mutual modification enhance introduced. TFN challenges include difficulty controlling polymer layer performance limitations caused “trade-off” effect. can modulate formation process establish transport channels within matrix effect limitations. review focuses on mechanisms synergistic construction polymer–MOF structure–nanofiltration relationships, have not been sufficiently addressed past.

Thin-Film Composite Polyamide Membranes Modified with HKUST-1 for Water Treatment: Characterization and Nanofiltration Performance

Polymers, Journal Year: 2025, Volume and Issue: 17(9), P. 1137 - 1137

Published: April 22, 2025

The development of sustainable nanofiltration membranes requires alternatives to petroleum-derived polymer substrates. This study demonstrates the successful use an eco-friendly cellulose acetate/cellulose nitrate (CA/CN) blend substrate for fabricating high-performance modified thin-film composite (mTFC) membranes. A dense, non-porous polyamide (PA) selective layer was formed via interfacial polymerization method and with 0.05–0.1 wt.% HKUST-1 (Cu3BTC2, MOF-199). Characterization by FTIR, XPS, SEM, AFM, contact angle measurements confirmed CA/CN substrate’s suitability TFC membrane fabrication. incorporation created a distinctive ridge-and-valley morphology while significantly altering PA hydrophilicity roughness. mTFC performance could be fine-tuned controlled HKUST-1; through aqueous phase slowed down formation reduced its thickness, addition organic resulted in denser due agglomeration. Thus, either enhanced permeability (123 LMH bar−1 0.05 aqueous-phase incorporation) or rejection (>89% dye removal organic-phase were achieved. Both also exhibited improved heavy metal ion (>91.7%), confirming their industrial potential. Higher loading (0.1 wt.%) caused MOF agglomeration, reducing performance. approach establishes fabrication route tunable targeting specific separation tasks.
