hermally conductive polymer composites offer new
possibilities for the thermal management in electronic
devices. An approach of current interest to improve the
thermal conductivity of polymer composites is the addition of
hybrid nano and micro fillers with high thermal conductivity.
The objective of this paper is to study the effective thermal
conductivity of the composites with nano and micro fillers.
The nano fillers used were carbon nanotubes and alumina
nanowires, and the alumina and boron nitride particles with
different shape and size were selected as the micro fillers.
The random close-packed structures of micro fillers were
obtained using packing simulations, and finite element
analyses were performed to predict the composite thermal
conductivity. In addition, experimental measurements of
the thermal conductivity of the manufactured polymer
composites were carried out by using a steady-state method.
The microstructure of the composites was also examined
using a scanning electron microscope. The results showed
that the addition of nano fillers to the matrix significantly
increased the thermal conductivity of the composites with
close-packed structure of micro fillers.

Dr. Kazuaki Sanada received his Doctor of Engineering from Tohoku University in 1999.
From 1999 until 2003 he worked as a researcher at Hitachi, Ltd. He is currently a
professor in the Department of Mechanical Systems Engineering at Toyama Prefectural
University, which he joined in 2003. Dr. Sanada is primarily interested in the fabrication
and evaluation of carbon nanotube/polymer composites, the microstructural
design and characterization of thermally conductive polymer composites, and the
development of self-healing composites.
