Current research on emergent membrane materials with ordered and stable nanoporous structures often overlooks the vital facet of manufacturing scalability. We propose the preprocessed monomer interfacial polymerization (PMIP) strategy for the scalable fabrication of high-valent cluster-based metal–organic framework (MOF) membranes with robust structures. Using a roll-to-roll device on commercial polymer supports, Zr-fum-MOF membranes are continuously processed at room temperature through the PMIP approach. These large-area membranes demonstrate the preeminent hydrogen separation capabilities, boasting an order of magnitude of permeance and a thrice-enhanced selectivity when juxtaposed with conventional polymeric membranes. The obtained PMIP-Zr-fum-MOF membranes possess superior stability in water compared with interfacial polymerization (IP)-processed low-valent metal-ion-based ZIF-8 membranes. Moreover, we have implemented the PMIP strategy’s universality to process the other four diverse MOF membranes. The proposal of PMIP significantly advances the scalable fabrication of water-stable high-valent cluster MOF membranes.

用于放大制造基于高价团簇的金属-有机框架膜的预处理单体界面聚合


目前对具有有序和稳定纳米多孔结构的新兴膜材料的研究往往忽视了制造可扩展性的重要方面。我们提出了预处理单体界面聚合 （PMIP） 策略，用于可扩展制造具有坚固结构的基于高价团簇的金属有机框架 （MOF） 膜。在商业聚合物载体上使用卷对卷装置，通过 PMIP 方法在室温下连续加工 Zr-fum-MOF 膜。这些大面积膜展示了卓越的氢分离能力，与传统聚合物膜并列时，具有一个数量级的渗透率和三倍增强的选择性。与界面聚合 （IP） 处理的低价金属离子基 ZIF-8 膜相比，所获得的 PMIP-Zr-fum-MOF 膜在水中具有优异的稳定性。此外，我们还实施了 PMIP 策略的通用性，以处理其他四种不同的 MOF 膜。PMIP 的提议显着推进了水稳定高价簇 MOF 膜的可扩展制造。
