In　order　to　improve　the　barrier　and　antistatic　properties　of　thermoplastic　polyurethane　(TPU),　original　carbon　nanotubes　(CNTs)　were　added　into　functional　modification　reduced　graphene　oxide　(FRGO),　and　hybrid　particles　FRGO-CNTs　which　were　uniformly　dispersed　in　N,　N-dimethylformamide　(DMF)　were　prepared　by　non-covalent　modification　firstly.　Then,　FRGO-CNTs/TPU　composite　films　were　fabricated　by　solution　coating　method　on　the　coating　machine.　Finally,　the　structures　and　properties　of　FRGO-CNTs/TPU　composite　films　were　characterized　by　FTIR,　XRD,　XPS,　FE-SEM,　TG,　oxygen　transmission　rate　tester,　high　resistance　meter　and　universal　testing　machine.　The　results　demonstrate　that　FRGO　and　CNTs　produce　synergistic　effect　through　π-π　conjugation,　and　the　prepared　FRGO-CNTs　show　good　compatibility　with　TPU　matrix.　When　FRGO-CNTs　content　(using　TPU　as　reference)　is　2.0wt%,　the　thermal　decomposition　temperature　of　composite　film　increases　by　49℃,　and　the　oxygen　transmission　rate　decreases　by　53.7%.　The　FRGO　with　large　specific　surface　area　and　the　CNTs　with　high　length　to　diameter　ratio　can　build　the　conductive　network　in　TPU　matrix.　When　FRGO-CNTs　content　is　only　0.8wt%,　the　volume　resistivity　of　FRGO-CNTs/TPU　composite　film　declines　by　as　much　as　7　orders　of　magnitude.　Meanwhile,　with　the　FRGO-CNTs　content　increasing,　the　tensile　strength　and　elongation　at　break　of　composite　films　both　rise　at　first　and　then　go　down.　©　2016,　BUAA　Culture　Media　Group　Ltd.　All　right　reserved.
