Gas permeation performance of PVDF based composite membrane embedded with CuBTC MOF

Semicrystalline poly(vinylidene fluoride) (PVDF) was used to make mixed matrix membranes by incorporating crystalline metal−organic framework (MOF) of CuBTC. Strong adhesion of CuBTC to PVDF was achieved up to 10% loading of CuBTC. The maximum selectivity of 123.3, 101.08 and 41.11 were obtained with 10% CuBTC loading for He/CH4, He/N2 and CO2/CH4 respectively. 15% loading of CuBTC in PVDF created non-selective void due to the particle agglomeration and although the highest permeability was obtained in this loading, selectivity declined significantly
