Mixed-matrix membranes (MMMs) composed of a metal–organic framework (MOF, UiO-66) and a poly(ethylene-co-vinyl acetate) (EVA) copolymer were synthesized with a range of MOF loadings. The MOF pores in these MMMs are accessible by gas sorption measurements and susceptible to postsynthetic modification and exchange. In addition, the MMMs were tested for their utility in three potential aqueous applications: dye separation, sorption and removal of perfluoroalkanes, and catalytic breakdown of a chemical warfare agent simulant. These studies also show that choice of polymer binder for the MMM affects the composite performance, despite it being a minority component of these MOF-dominant MMM composites.

从聚制备的金属-有机骨架混合基质膜的液相应用（乙烯-共-乙烯基乙酸酯）

一个金属-有机骨架组成的混合基质膜（MMM中）（MOF，UIO-66）和聚（乙烯-共-乙酸乙烯酯）（EVA）共聚物，用一系列MOF载荷的合成。这些MMM中的MOF孔可通过气体吸附测量获得，并且易于合成后的修饰和交换。此外，还对MMM在三种潜在的水性应用中的效用进行了测试：染料分离，全氟烷烃的吸附和去除以及化学战剂模拟物的催化分解。这些研究还表明，尽管MMM聚合物粘合剂是这些以MOF为主的MMM复合材料中的少数组分，但选择聚合物粘合剂会影响复合材料的性能。
