N2 - In this work, nanocomposites of poly(lactic) acid incorporating two kinds of highly thermal conductive graphene nanoplatelets differing in size and purity were fabricated by melt extrusion. Nanocomposites of 1.5–9 wt% filler contents were characterized using thermal constant analysis, X-ray diffraction and infrared spectroscopy to clarify their functionality, related to composition and morphology. The thermal conductivity increases linearly with increasing the filler concentration, but it is essentially determined by the size and purity of fillers and thermal interfacial resistance.
