Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Mixed-matrix membranes (MMMs) comprising Matrimid and a microporous azine-linked covalent organic frameworks (ACOF-1) were prepared and tested in the separation of CO2 from an equimolar CO2/CH4 mixture. The COF-based MMMs show a more than doubling of the CO2 permeability upon 16wt% ACOF-1 loading together with a slight increase in selectivity compared to the bare polymer. These results show the potential of COFs in the preparation of MMMs.
