Mixed matrix membranes of Matrimid 5218 loaded with zeolite 4A for pervaporation separation of water-isopropanol mixtures

► Zeolite 4A was incorporated into glassy Matrimid 5218 to form defect free MMMs. ► Effects of filler loading incorporation on MMMs and their structure were studied. ► Effects of operating parameters on PV performance were studied. ► Considerable higher MMM IPA dehydration S. F. was observed compared with polymeric one.
