Abstract：

Mixed　matrix　membranes　are　attracting　increasing　attention　due　to　their　potential　to　provide　selective　channels　in　the　polymer　matrix.　However,　the　compatibility　and　dispersion　of　nanoparticles　in　organic　polymers　are　still　challenging　in　membrane　preparation　procedure.　Covalent　organic　frameworks　(COFs)　are　excellent　nano-fillers　due　to　their　good　compatibility　with　organic　polymers.　In　this　work,　LZU8　particles　were　incorporated　into　polydimethylsiloxane　(PDMS)　membranes.　SEM　observations　showed　that　the　LZU8　particles　were　well　dispersed　in　the　PDMS　matrix.　Additionally,　the　viscosity　changes　of　membrane　solution　and　the　LF-NMR　result　of　the　crosslinked　membranes　showed　that　the　incorporation　of　LZU8　could　accelerate　the　crosslinking　of　the　PDMS　solution.　The　LZU8-PDMS　membrane　was　applied　for　the　pervaporation　of　5　wt%　ethanol/water　solution,　which　exhibited　a　high　flux　of　5　kg　m2·h-1　and　a　separation　factor　of　11.　Considering　the　compatibility　of　inorganic　particles　with　polymer　and　the　controlling　of　crosslinking　could　be　critical　factors　in　mixed　matrix　membranes　fabrication　procedure,　this　LZU8　can　be　a　promising　nano-filler　for　improving　the　performance　of　membranes.　©　2024　Elsevier　B.V.
