Abstract

Abstract: 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 16 wt % 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. Abstract : COF‐based MMMs show a more than doubling of the CO2 permeability upon 16 wt % ACOF‐1 loading together with a slight increase in selectivity compared to the bare polymer (see figure).
