Uniform zeolitic imidazolate framework (ZIF-8) nanoparticles were synthesized then dispersed into a rubbery polydimethylsiloxane (PDMS) matrix to prepare ZIF-8/PDMS hybrid membranes. The performance of the ZIF-8/PDMS hybrid membrane was evaluated in ethanol-water and aromatic-water model systems. The ZIF-8/PDMS hybrid membranes, loaded with 6 wt% of the nanoparticles, separated of ethanol and the characteristic compounds in blackberry juice, linalool, benzaldehyde and ethyl acetate more effectively than a pure PDMS membrane. Based on these results, a ZIF-8/PDMS hybrid membrane was used to sepa...
