In comparison to other polymer membranes, soluble porous networks hold an advantage in gas separations in the form of thin solution-cast films. Linear PIMs are soluble and thus good candidates in this regard. The introduction of triazole groups in PIMs (TZPIMs) by post-synthetic modification favors CO2 uptake and greater selectivity for gas separation. TZPIM membranes exhibit exceptional selective permeation as polymeric membranes for gas mixtures like CO2 and N2.
