| Outline of Final Research Achievements |
This study aims to develop polymer composites with high thermal conductivity and good processability using nano- and micro-fusible particles. Polymer composites were prepared by mixing liquid-type epoxy resin with a curing agent, an accelerator, and nano- and micro-fusible particles. The nano-fusible particles were a mixture of fusible-powdered epoxy resin with low fusible temperature and carbon nanotubes (CNTs), whereas the micro-fusible particles were a mixture of fusible-powdered epoxy resin with high fusible temperature and carbon fibers. The nano- and micro-fusible particles fused during the cure of epoxy matrix and form thermally conductive pathways in the composites. The viscosity of the uncured composites was measured using a viscometer. Moreover, the thermal conductivity of the cured composites was evaluated using a steady-state method. The effect of addition of the nano- and micro-fusible particles on the thermal conductivity and viscosity of the composites is discussed.
