A small series of functionalized C60-fullerene/epoxy nanocomposites were prepared, and their respective ultimate tensile strengths were determined. The functionalization route of the fullerenes was performed using the well-known Prato reaction, with modified amino acids, resulting in the formation of N-pyrrolidine rings across the [6,6] junctions. Characterization of the functionalized fullerenes was done using LDI-TOF mass spectrometry. By the type of modified amino acid, the degree of functional group attachment, and the consequent degree of dispersion into the epoxy matrix, the mechanical properties of the nanocomposites were affected. We used a specially blended epoxy matrix by using a lower molecular weight diglycidyl ether, in conjunction with the more recognized diglycidyl ether of bisphenol A (DGEBA). The viscosity of the overall epoxy matrix was decreased by blending the more recognized diglycidyl ether of bisphenol A (DGEBA) with this lower molecular mass diglycidyl ether, thereby allowing easier mixing conditions.
