Preparation and characterization of ZIF-8 and ZIF-67 engineered PVDF mixed-matrix membranes: Stability enhancement in pervaporation study

Mono-(ZIF-8 and ZIF-67) and bi-metallic (ZIF-8-67) MOFs are used as fillers for MMMs. The prepared MMMs enhance the separation performance. All the prepared MMMs show stable separation performance for 220 h of experiments.
