The loading obtained was substantially higher (50%) than generally observed with MOFs. These hybrid membranes show an exciting enhancement in permeability (about sevenfold) with appreciable separation factors for CO2/N-2 and CO2/CH4. Further, we found that with COF pore modulation, the gas permeability can be systematically enhanced.</p>10acovalent organic frameworks10aGas separation10amembranes10amicroporous materials10apore modulation1 aBiswal, Bishnu, P.1 aChaudhari, Harshal, D.1 aBanerjee, Rahul1 aKharul, Ulhas, K.  uhttps://library.ncl.res.in/content/chemically-stable-covalent-organic-framework-cof-polybenzimidazole-hybrid-membranes-enhanced
