Abstract
▸ Diffusivities of ethanol/water mixtures in PDMS-zeolite films are measured. ▸ Both ethanol and water permeants exhibit similar diffusivities in PDMS film. ▸ Ethanol-over-water diffusion selectivity in PDMS-(30%)zeolite membrane is 2.4−3.5. ▸ Diffusion selectivity increases steadily as zeolite load increasing from 0% to 30%.
