用于气体分离的混合基质膜（MMM）传统上由分散在聚合物基质中的沸石组成，以改善所需的渗透剂渗透性和选择性。沸石对于该应用具有多种缺点-主要是，有限数量的可能沸石结构-这限制了它们在MMM中使用的潜力。金属有机框架（MOFs），一个相对较新的一类微孔材料，没有很好地研究用于MMM。M0 F是在MMM中使用沸石的有吸引力的替代物，因为可能的结构的数量实际上是无限的。在这项工作中，一个MOF的铜和对苯二甲酸（CuTPA）的合成，表征，并用于制造金属陶瓷。这些CuTPA MMM的气体传输性能显示出比纯聚合物气体传输性能的改善。(C)2009 Elsevier Inc.

Mixed matrix membranes (MMMs) for gas separations are traditionally comprised of zeolites dispersed in a polymer matrix in order to improve desired penetrant permeability and selectivity. Zeolites have a variety of drawbacks for this application - chiefly, a limited number of possible zeolite structures - that limit their potential for use in MMMs. Metal organic frameworks (MOFs), a relatively new class of microporous materials, are not well studied for use in MMMs. MOFs are an attractive alternative to the use of zeolites in MMMs because the number of possible structures is effectively infinite. In this work, a MOF of copper and terephthalic acid (CuTPA) was synthesized, characterized, and used to make MMMs. The gas transport properties of these CuTPA MMMs showed improvements over the pure polymer gas transport properties.
