The diverse chemical and structural properties of metal-organic frameworks (MOFs) make them attractive for myriad applications, but their native powder form is limiting for industrial implementation. Composite materials of MOFs hold promise as a means of exploiting MOF properties in engineered forms for real-world applications. While interest in MOF composites is growing, research to date has largely focused on utilization of single MOF systems. The vast number of different MOF structures provides ample opportunity to mix and match distinct MOF species in a single composite to prepare multifunctional systems. In this work, we describe the preparation of three types of multi-MOF composites with poly(vinylidene fluoride) (PVDF): (1) co-cast MOF MMMs, (2) mixed MOF MMMs, and (3) multilayer MOF MMMs. Finally, MOF MMMs are explored as catalytic membrane reactors for chemical transformations.
金属有机框架材料（MOFs）多样的化学和结构特性使其在众多应用中颇具吸引力，但其原生粉末形式限制了工业应用。MOFs复合材料有望成为一种以工程化形式利用MOF特性用于实际应用的手段。虽然对MOF复合材料的兴趣与日俱增，但迄今为止的研究主要集中在单一MOF体系的利用上。大量不同的MOF结构为在单一复合材料中混合和匹配不同的MOF物种以制备多功能体系提供了充足的机会。在这项工作中，我们描述了三种含聚偏氟乙烯（PVDF）的多MOF复合材料的制备方法：（1）共铸MOF混合基质膜，（2）混合MOF混合基质膜，以及（3）多层MOF混合基质膜。最后，对MOF混合基质膜作为化学转化的催化膜反应器进行了探索。
