MUF-15 (MUF = Massey University Framework) is a metal–organic framework with pores that can be tuned by ligand functionalisation. Crystallites of MUF-15 and derivatives were blended with the organic polymer 6FDA-DAM to produce mixed-matrix membranes (MMMs). At a loading of 30 wt%, membranes with MUF-15-F, MUF-15 with an appended fluoro group, exhibited a CO₂ permeability of 1300 Barrer and CO₂/CH₄ selectivity of 37.1. These values surpass membranes with the parent MUF-15 and exceed the Robeson upper bound.

MUF-15 的功能化增强了混合基质膜中 CO2/CH4 的选择性

MUF-15（MUF = 梅西大学框架）是一种金属有机框架，其孔隙可通过配体功能化进行调节。 MUF-15 及其衍生物的微晶与有机聚合物 6FDA-DAM 混合以生产混合基质膜 (MMM)。在负载量为30wt％时，具有MUF-15-F、带有附加氟基团的MUF-15的膜表现出1300Barrer的CO _{2渗透性和37.1的CO 2} /CH ₄选择性。这些值超过了母体 MUF-15 的膜，并超过了 Robeson 上限。
