Abstract: Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did not significantly alter the compressive strength, or hardness of the composites in comparison to the pure matrix. It was concluded that these materials had potential to eventually be used as thermal interface materials.
