Abstract

A nanoscale hybrid filler comprising single-walled carbon nanotubes and graphite nanoplatelets provides a synergistic effect in the enhancement of thermal conductivity of epoxy composites, which is ascribed to the formation of a more efficient percolating network with significantly reduced thermal interface resistance.
