Enhancement of electrical insulation properties of epoxy nanocomposites with fullerenes

In this paper, we propose to study the synthesis of fullerene nanoparticles (C60-C80) by electric arc method and to show the impact of very low filler content (0.005 wt.%) of those nanofillers on the electrical conductivity versus electric field of an epoxy nanocomposite. The results highlight a decrease in the DC electrical conductivity of the epoxy/fullerenes compared to that of neat epoxy in a large range of electric field from 1 to 6 kV/mm. This shows an improvement of the charge trapping efficiency.
