摘要：

To　improve　the　dielectric　properties　of　dielectric　material,　an　in-situ　polymerization　method　was　used　for　preparing　the　combined　functional　filler　BT/PANI,　and　three-phase　composite　BT/PANI/PVDF　was　prepared　using　BT-PANI　as　the　functional　phase.　The　structure　of　BT/PANI　was　characterized　by　infrared　spectroscopy　(IR)　and　X-ray　diffraction　(XRD).　The　morphology　and　dielectric　properties　of　the　three-phase　BT/PANI/PVDF　were　characterized　by　scanning　electron　microscopy　(SEM)　and　impedance　analyzer.　The　polarization　modes　of　the　BT/PANI/PVDF　system　were　analyzed,　and　the　variations　of　dielectric　properties　with　frequency　were　explained　based　on　it.　Results　show　that　the　functional　phase　BT/PANI　is　uniformly　coated　by　polymer　matrix　in　BT/PANI/PVDF　to　obtain　good　dielectric　properties.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
