High-density polyethylene/fullerene (HDPE/C 60) nanocomposites with the C 60 loading that varied from 0.5 to 5.0 by weight were prepared via melt compounding. Thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) results showed that the presence of C 60 could remarkably enhance the thermal properties of HDPE. A very low C 60 loading (0.5wt) increased the onset degradation temperature from 389°C to 459°C and decreased the heat release from 3176J/g to 1490J/g. The larger the loading level of C 60, the better the thermal stability of HDPE/C 60 nanocomposites. Rheological investigation results showed that the free radical trapping effect of C 60 was responsible for the improved thermal stability of HDPE.
