Thermally Conductive Nanocomposites Based on Epoxy Modified with SiC and POSS

OAPS/SiC/EP, SiC/EP, A151-SiC/EP composites were prepared and their impact properties, flexural properties, thermal conductivity and insulation and thermal stability were investigated. The comparison of three different composites showed that OAPS/SiC/EP composites had best properties. The thermal conductivity of OAPS/SiC/EP composites increased with increasing filler content. The thermal conductivity of OAPS/SiC/EP composites with 20 wt% SiC was 0.34 W/mK and was 55% higher than that of unmodified EP.
