To take full advantage of epoxy nanocomposites with carbon nanofillers, homogeneous dispersion and strong interfacial bonding are essential. Therefore, in this study, amine groups were introduced on the surfaces of carbon nanofillers (carbon nanofiber, single-wall, multi-wall carbon nanotubes) via treating them with 4-aminobenzoic acid in polyphosphoric acid. Epoxy nanocomposites comprising different carbon nanofillers were prepared and their characteristics were compared to each other. According to the SEM images of the fractured-surfaces of the nanocomposites, the functionalization induced strong interfacial bonding resulting in considerable improvements in the performance of the nanocomposites. |
