Abstract: Nano-sized materials with large aspect ratios are found to be effective as second fillers for the formation of 3D thermally conductive networks in polymer composites. In this study, multi-walled carbon nanotube (MWCNT) was incorporated as second filler for polymer composites. A thermal analyzer was used to measure thermal conductivity of composites at room temperature. Expanded graphite and MWCNT, as fillers, effectively enhanced thermal conductivity of the composites due to its unique structure.
