Cover Story: We prepared and characterized mixed-matrix membranes based on amorphous PPO and particles of the molecular sieve ZIF-8. The inclusion of ZIF-8 with loadings as high as 45 wt % led to a remarkable, up to eight-fold, increase in gas permeability and to a significant decrease in the activation energy of diffusion and permeation. The ideal He/CO2 selectivity also increased, albeit to a lower extent, reaching a maximum at a filler loading of 35 wt %. The additive behavior observed in density measurements and the morphological analysis of the composite films indicate good adhesion between the two phases. The use of commercial materials enables the possibility of scaling-up the technology, and the results encourage applications at high temperatures. View this paper
