Researchers investigated the effects of fullerene (C60) on the mechanical properties of epoxy nanocomposites. For this purpose, Fullerene (C60) was oxidized first and then silanized using 3-Aminopropyltriethoxysilane (APTES). It was claimed that The formation of active functional groups on silanized C60 regulated the polymer assembly and its coordination that enhances scratch recovery index (~32%), wear resistance (~57%) and microhardness (~19 %) of epoxy composites. When silanized C60 was used as nanoreinforcement in epoxy, the tensile strength, elastic modulus, and fracture toughness was enhanced by ~ 28%, ~30%, and ~67.5% respectively for the epoxy nanocomposites.
