Encapsulated functionalized graphene oxide or boron nitride on poly(methyl methacrylate) beads for thermally conductive epoxy nanocomposites |
| 초록 |
The thermally conductive nanofillers were prepared by encapsulating the functionalized graphene oxide or boron nitride as the shell on the plasma treated poly(methyl methacrylate) beads as the core by electrostatic interaction (nanofiller@PMMA). The core-shell beads was incorporated into epoxy matrix to fabricate the thermally conductive epoxy nanocomposite. Scanning electron microscopy images show that the shell showed a network structure covering the whole surface of the core (pPMMA bead) and simultaneously overlaps the same of the adjacent beads and thus continuous conductive pathways are formed among the filler beads. The epoxy composites prepared with functionalized graphene oxide shell shows a thermal conductivity of ~ 0.60 W·m -1 ·K -1 which was much higher than that of hexagonal boron nitride shell embedded in epoxy composites at an overall nanofiller content of 1.0 wt%. *This study was supported by Korea National University of Transportation in 2018. |
