FGNRs-CNFs/thermoplastic　polyurethane(TPU)　composite　films　were　prepared　by　solution　coating　method　on　a　coating　machine.　FT-IR,　XRD,　XPS　and　TEM　were　used　to　characterize　the　structure　and　properties　of　the　as-prepared　FGNRs-CNFs.　Meanwhile,　combining　with　the　oxygen　transmission　rate,　the　volume　resistivity　test,　and　the　fractured　surface　morphology,　the　effect　of　different　FGNRs-CNFs　content　on　the　barrier　and　antistatic　properties　of　TPU　composite　films　was　studied.　The　results　show　that　KH-550　is　successfully　grafted　on　GNRs,　and　the　FGNRs　adhere　to　the　surface　of　the　CNFs　to　forming　stable　FGNRs-CNFs　network　structure,　which　is　beneficial　for　the　dispersion　of　FGNRs-CNFs　in　TPU　matrix.　Comparing　with　the　pure　TPU,　the　oxygen　transmission　rate　of　the　FGNRs-CNFs/TPU　composite　films　is　reduced　by　68.8%,　and　the　barrier　property　is　improved　greatly　when　the　mass　fraction　of　the　FGNRs-CNFs　is　1%;　the　conductivity　of　FGNRs-CNFs/TPU　composite　films　is　promoted　by　7　orders　of　magnitude　as　the　FGNRs-CNFs　mass　fraction　is　0.6%,　because　the　formation　of　conductive　network　between　FGNRs　and　CNFs　improves　the　room　temperature　conductivity　of　composite　films.　©　2016,　Editorial　Board　of　Polymer　Materials　Science　&　Engineering.　All　right　reserved.
