Organic　solvent　nanofiltration　(OSN)　is　an　emerging　technology　for　molecular　separation　and　purification　in　organic　media.　The　separation　performances　are　mainly　depended　on　the　material　and　structure　of　the　membrane.　In　this　study,　Zeolitic　Imidazolate　Framework　(ZIF-8)　nanoparticles　were　in　situ　growth　onto　the　surface　of　graphene　oxide　(GO)　sheets　to　form　ZIF-8@GO　composites,　which　were　co-deposited　with　polyethyleneimine　(PEI)　matrix　on　tubular　ceramic　substrate　through　a　vacuum-assisted　assembly　method.　The　dispersion　of　ZIF-8　nanoparticles　in　PEI　matrix　as　well　as　the　compactness　and　uniformity　of　the　composite　membranes　were　readily　improved　due　to　the　templating　effect　of　lamellar　GO　sheets　and　the　transmembrane　pressure.　Membrane　performance　in　OSN　was　evaluated　on　the　basis　of　methanol　permeance　and　retention　of　dye　molecules.　Methanol　permeance　increased　when　ZIF-8@GO　laminates　were　embedded　into　the　PEI　layer,　whereas　the　retention　remained　higher　than　99%.　The　improvement　of　separation　performance　may　be　due　to　the　well　dispersion　of　ZIF-8　nanoparticles　in　PEI　matrix,　which　offers　more　well-defined　pathways　for　solvent　molecules.　Building　on　these　findings,　we　demonstrate　a　simple　scalable　method　to　obtain　robust　ZIF-8@GO　based　membranes　with　enhanced　OSN　performance.
