This paper reports the effects of synthesis time, temperature, and reactant ratio on ZIF-71 particle size and the effect of particle size on membrane performance. Temperature has the greatest effect on particle size, as the synthesis temperature varies from −20 °C to 35 °C. The synthesized ZIF-71 has particle diameters ranging from 150 nm to 1 μm. ZIF-71 particle size is critical in ZIF-71/PDMS composite membrane performance for ethanol and 1-butanol removal from water through pervaporation. The membranes that are made with micrometer-sized ZIF-71 particles exhibit higher alcohol/water selectivity than those with smaller particles. Both alcohol and water permeability increase when larger-sized ZIF-71 particles are incorporated, because the pathways through the membranes are less tortuous.
