CALF-20, [Zn 2 (1,2,4-triazolate) 2 (oxalate)] shows remarkable performance in post-combustion carbon capture, even under humid conditions 1 but its reported crystal morphology hinders its applicability in mixed matrix membranes (MMMs). Here, a route to its preparation as platelets a few tens of nm thick is reported. These were incorporated into a PEBAX MH1567 polymer matrix and the resultant MMMs display improvement in CO 2 permeability and CO 2 /N 2 selectivity.
