Metal–organic framework (MOF) based mixed matrix membranes (MMMs) have received significant attention in applications such as gas separation, sensing, and energy storage. However, the mass production of MOF‐based MMMs with retained porosity remains a longstanding challenge. Herein, an in situ heat‐assisted solvent‐evaporation method is described to facilely produce MOF‐based MMMs. This method can be extended into various MOFs and polymers with minimum reaction time of 5 min. Thus‐obtained MMMs with high uniformity, excellent robustness, well‐tuned loading, and thickness can be massively produced in industrial‐level efficiency (≈4 m in a batch experiment). Furthermore, they can be readily applied as powerful separators for Li–S cell with high specific capacity (1163.7 mAh g⁻¹) and a capacity retention of 500.7 mAh g⁻¹ after 700 cycles at 0.5 C (0.08% fading per cycle). This work may overcome the longstanding challenge of processing MOFs into MMMs and largely facilitate the industrialization process of MOFs.

以工业级效率快速生产基于金属-有机框架的分离器

基于金属有机框架（MOF）的混合基质膜（MMM）在气体分离，传感和能量存储等应用中受到了广泛关注。然而，具有孔隙率的基于MOF的MMM的批量生产仍然是一项长期挑战。在此，描述了一种原位热辅助溶剂蒸发方法，以方便地生产基于MOF的MMM。该方法可以扩展到各种MOF和聚合物中，最短反应时间为5分钟。这样获得的MMM具有很高的均匀性，出色的鲁棒性，良好的负载和厚度，可以工业水平的效率大批量生产（批处理实验中≈4m）。此外，它们可以轻松用作具有高比容量（1163.7 mAh g ^-1）并在0.5 C下进行700次循环后的容量保持率为500.7 mAh g ^-1（每循环0.08％褪色）。这项工作可以克服将MOF加工成MMM的长期挑战，并在很大程度上促进MOF的产业化过程。
