Abstract: The effects of intrinsic thermal conductivity, carbon filler geometry, and interface thermal resistance on the effective thermal conductivity of polymer composites were investigated. It was found that the length of carbon fillers and the interface thermal resistance were the dominant factors in determining the effective thermal conductivity of the composites. The authors suggest that the most thermally conductive polymer composite would contain long carbon nanofibers that have undergone surface functionalization to reduce interface thermal resistance.
