Mixed Matrix Membranes Based on Metal Organic Frameworks

John P. Ferraris, Inga H. Musselman and Kenneth J. Balkus

Abstract

Mixed-Matrix Membranes (MMM) could provide a near term solution to the permeability/selectivity trade-off with polymeric gas separation membranes and bridge the gap with inorganic membranes. While zeolite and carbon additives have shown promise, the corresponding mixed-matrix membranes are limited by low loadings and interfacial defects such that the true potential of MMMs has not been realized. Metal-Organic Frameworks (MOF), on the other hand, provide exceptionally high surface areas and organic linkers that could enhance selective gas transport and improve polymer/particle interactions. In this review, recent theoretical and experimental results for MOF-based mixed-matrix membranes will be described.
