英文摘要: Abstract(#br)Zeolitic Imidazolate Framework (ZIFs) have received much attention in recent years because of their good compatibility with polymer, and their ultramicroporosities that are in the range of the kinetic diameter of several important gas and liquid molecules. In this study, three different ZIF particles, i.e., ZIF-90 and its derivatives (ZIF-91 and ZIF-92) were synthesized and incorporated into polydimethylsiloxane (PDMS) matrix to fabricate ZIF/PDMS nanocomposite membrane for pervaporation recovery of ethanol. The morphologies and structures of ZIF particles and their nanocomposite membrane were characterized by various techniques. The results show that ZIF-91 particles with hydroxyl functional groups have good compatibility with PDMS and are dispersed well in PDMS matrix....
