Study on the bridge effect of Graphene oxide on thermal conductivity of Al2O3 filled glass fibers reinforced polymer composites

摘要：

　　Al2O3 particles linked by graphene oxide sheets(GO-linked Al2O3),were fabricated via self-assembly leading by electrostatic attraction and incorporated into the glass fibers reinforced polymer composites(GFRPC)to improve their thermal conductivities.Flexible and ultrathin GO sheet was able to bridge adjacent Al2O3 particles,which would contribute to form thermally conductive pathways.Addition of GO sheets resulted in great enhancement of thermal conductivity with the highest value of 0.95 W/m·K,which was increased by 37.6%compared to composite with raw Al2O3.Moreover,the dielectric constant and loss increased for adding GO sheets exacerbated interfacial polarization.The study will provide new guide for preparing high thermally conductive GFRPC.
