Abstract
Highdensity polymer composites with semiconductor or dielectric fillers such as aluminum nitride AIN aluminum oxide Al2O3 titanium carbide TiC titanium nitride TiN boron nitride BN silicon nitride Si3N4 and titanium carbonitride TiCN were prepared by the hot pressing method Each powder phase of the composites was exposed to an electric discharge plasma process before composite formation The effects of the electric discharge plasma process and the filler content volume fraction on the thermal conductivity volt–ampere characteristics thermally stimulated depolarization current as well as electrical and mechanical strength were investigated The results of the study indicate that with increasing filler volume fraction the thermal conductivity of the samples also increased Furthermore the thermal conductivity and electrophysical and mechanical properties of the highdensity polyethylene + 70 BN composite modified using the electric discharge plasma showed improvement when compared with that without electric discharge plasma treatment
