초록

The newly combined zeolite imidazole frameworks-8 (ZIF-8) and poly(vinyl chloride)-g-poly(oxyethlyene methacrylate) (PVC-g-POEM) graft copolymer mixed matrix membrane (MMM) is developed for gas separation. PVC-g-POEM graft copolymer, synthesized by atom transfer radical polymerization (ATRP) process, plays a pivotal role as a soft matrix to provide good permeation, uniform distribution of ZIF-8, and better interfacial interaction with inorganic filler. Moreover, addition of ZIF-8 in MMM enhances gas diffusion through pore in framework as well as gas solubility in organic linker. These synergetic functionalities dramatically improve gas separation performance, which MMMs loading ZIF-8 exhibited enhanced permeability and selectivity compared to neat graft copolymer membrane as measured via the time-lag method.
