Plasticization is one of the biggest challenges in gas separation polymeric membranes. Mixed matrix membrane (MMM) comprising inorganic nanofiller is the most promising solution for anti-plasticization, however, it requires large amount of nanofillers to achieve desired performance. We adopted 2-D nanocomposite of zeolitic imidazolate framework (ZIF) attached on graphene oxide to effectively prevent plasticization of polyimide membrane under mixed gas condition. ZIF nanofillers, known as suitable additive for olefin/paraffin separation membranes, were grown on graphene oxide 2-D nanotemplates to maximize encounter frequency between gas permeant and nanofillers even in lower concentrations. The prepared MMMs successfully showed an improved mixed gas selectivity compapred to pristine membrane, indicating better anti-plasticization effect.
