Polypropylene (PP)/C 60 nanocomposites with improved interfacial interaction were prepared via in situ melt radical reaction. It was found that the relaxation time of PP/C 60 nanocomposites containing peroxide increased due to the reaction between C 60 and PP macroradicals and the formation of long chain branched or crosslinking structure. Thermogravimetric analysis (TGA) results showed that the thermal stability of PP/C 60 nanocomposites was enhanced. The initial decomposition temperatures and activation energy of PP/C 60 nancomposites were strongly influenced by the content of unreacted C 60 . Because of the improved interfacial interaction, PP/C 60 nanocomposites containing peroxide showed obvious increase in tensile strength, Young' modulus, flexural strength, flexural modulus, and impact strength, compared to PP/C 60 nanocomposites (without peroxide) containing the same content of C 60 .
