Fluorinated MOF-808 with various modulators to fabricate high-performance hybrid membranes with enhanced hydrophobicity for organic-organic pervaporation

Highly efficient PDMS based membranes with a new type of fluorinated MOF-808 were successfully prepared and used for the first time in pervaporation (PV). Two types ligands i.e. trifluoroacetic acid (TFA) pentafluoropropionic (PFPA) during MOF synthesis. These slightly different size chemical character influenced material properties membranes, roughness, contact angle, surface free energy, thermal features. Incorporation MOFs enhanced membrane hydrophobicity performance organic-organic PV separation industrially important mixtures like, ethyl acetate-EtAc tert-butyl ether-ETBE. The filled possessed much better transport features than pristine PDMS. Substantial improvement modified 5 wt% (normalized Pervaporation Separation Index – PSIN = 1540 µm kg m?2 h?1) was observed relation to (PSIN 780 commercial Pervap™4060 150 m?2h?1), ETBE/EtOH. An added value study impact water traces (in range 0.1–0.3 wt%) feed on performance. level permeate dependent composition, loading, since presence hydrophobic restricted side.
