High density polyethylene/fullerene (HDPE/C₆₀) nanocomposites with the C₆₀ loading 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 C₆₀ could remarkably enhance the thermal stability of HDPE. A very low C₆₀ loading (0.5 % by weight) increased the onset degradation temperature from 389 ºC to 459 ºC and decreased the heat release from 3176 J/g to 1490 J/g. The larger the loading level of C₆₀, the better thermal stability of HDPE/C₆₀ nanocomposities. Rheological investigation results showed that the free radical-trapping effect of C₆₀ was responsible for the improved thermal stability of HDPE.
