Thermal conductivity and processability of polymer composites with boron nitride (BN) particles has been investigated experimentally. Polymer composites with BN particles were fabricated by using planetary centrifugal mixer. The viscosity of uncured polymer composites was measured by tuning-fork vibration method and the thermal conductivity of cured polymer composites were measured by steady-state method. The effect of BN volume fraction, addition of different reaction diluent and weight fraction of reaction diluent on the thermal conductivity was also discussed. The results showed that increasing BN volume fraction lead to increase in thermal conductivity and viscosity of the composites. Moreover, for the composite with 30vol%BN, addition of SR-8EGS to the polymer matrix lead to increasing thermal conductivity and decreasing viscosity of composites.
