Metal-organic framework (MOF) nanoparticles have been incorporated into a polymer matrix to form hybrid membranes. The hybrid membranes offer a significant improvement in gas separation performance and stability compared to a pure polymeric membrane. However, interfacial defects are often formed, resulting in non-selective void spaces between polymer and MOFs in the hybrid membranes. As a result, the interfacial defects reduce gas separation performance (i.e., selectivity) and stability. To address this concern, this study shows a remarkable technique, which is interfacial engineering between the polyimide matrix and MOF nanoparticles, to theoretically design the hybrid membranes. This talk will provide the interfacial design method, material, and transport characterization for MOF-polymer hybrid membranes.
