中国石油大学孙道峰团队报道,预处理单体界面聚合用于可扩展制备高价簇基金属有机骨架膜。2024年11月14日出版的《美国化学会杂志》发表了这项成果。

据悉,目前对具有有序稳定纳米孔结构的新兴膜材料的研究,往往忽略了制造可扩展性的重要方面。

研究人员提出了一种预处理单体界面聚合(PMIP)策略,用于可扩展地制造具有稳健结构的高价团簇基金属有机骨架膜。在商用聚合物支架上使用卷对卷装置,通过PMIP方法在室温下,连续处理制备成功Zr-fum-MOF膜。

这些大面积膜展示了卓越的氢分离能力,与传统的聚合物膜相比,具有一个数量级的渗透性和三倍的选择性提高。与界面聚合(IP)处理的低价金属离子基ZIF-8膜相比,所制得的PMIP-Zr-fum-MOF膜在水中具有更好的稳定性。

此外,该课题组还实现了PMIP策略的通用性,以加工其他四种不同的MOF膜。PMIP的提出极大地促进了水稳定高价MOF膜的规模化制造。

Abstract: 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.
