摘要

Herein, polyvinylidene fluoride (PVDF)/hyperbranched polyethylenimine (HPEI) blend matrix was infused with graphene oxide–zinc oxide (GO–ZnO) filler to fabricate mixed matrix membranes (MMMs). These membranes were investigated by dynamic mechanical–thermal analysis (DMTA), single and binary gas (CO2/N2 and CO2/CH4) experiments and for anti-plasticization performance. Varying loading fractions [0.1
