Several PPS/BN composites were prepared with respect to the BN weight fraction to develop palletized, injection moldable, and high thermal conductivity composites having high mechanical properties. Thermal conductivity of the composite was improved with respect to increasing BN weight fraction. PPS/BN/CNT hybrid composites were prepared by adding both small amount of CNTs and optimum amount of BN to improve thermal conductivity of the PPS/BN composites and examine the hybrid effect of BN-CNT fillers on thermal conductivity of the composite. Also, aerogel/epoxy composites were prepared with respect to volume fraction of aerogel and thermal conductivity of the composites was measured by using a heat flow meter to estimate insulating ability of the composites. For preventing aerogel pores from immersing with epoxy matrix, preparation method for the preserving aerogel pores in the composites was developed by using ethanol evaporation. |
