The thermal and flame retardancy properties of high-density polyethylene (HDPE)/ ethylene vinyl-acetate copolymer (EVA)/ fullerene C₆₀ nanocomposites were investigated by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and cone calorimetry with C₆₀ loading varied from 0.5 to 2% by weight. Dispersion of C₆₀ in HDPE/EVA blends was characterized by transmission electron microscopy (TEM). TGA and DSC results showed that the presence of C₆₀ could remarkably enhance the thermal property and cone calorimeter measurements indicated that C₆₀ could to some extent reduce the flammability of HDPE/EVA, with a significant reduction in peak heat release rate and a much longer time to ignition. Furthermore, the larger the loading level of C₆₀, the better the flame retardancy of HDPE/EVA/C₆₀ nanocomposites.
