| Abstract:By using aramid fabric （AF） fibrid as matrix， hexagonal boron nitride （h-BN） modified by dopamine （DA） as the thermal conductive filler the AF-PDA@h-BN binary paper-based composite was prepared with vacuum-assisted filtration. The successful modification of h-BN by dopamine （DA） was characterized by energy disperse spectroscopy （EDS）， laser Raman spectrograph and fourier infrared spectrometer （FT-IR）. The distribution of PDA@h-BN in the paper-based composite was observed by scanning electron microscope （SEM）. The insulation performance and thermal conductivity of paper-based composite were analyzed and characterized by the volume resistivity tester and thermal conductivity tester. The experimental results showed that the thermal conductivity achieved a 175% enhance from 0.12 W/（m·k） of the pristine paper to 0.33 W/（m·k） when the content of PDA@h-BN was 15%. Meanwhile， the volume resistivity of the prepared binary paper-based composites increased with the increase of PDA@h-BN content， the binary composite paper volume resistivity increased from 4.63×1013 Ω·m of base paper to 5.60×1014 Ω·m. The results indicated that the prepared binary paper-based composites had excellent thermal conductivity and insulation properties． |
