Abstract

Graphene-based epoxy nanocomposites have been produced by the ultrasonication of graphene oxide (GO), chemically modified GO and through two-phase extraction of GO water solution. All the samples have been post-cured and the thermal treatment provided a thermal in situ reduction of GO into the epoxy reticulated matrix. Electrical conductivity of the samples has been measured showing different behavior depending on both the nanofiller and the production procedure employed. Sample with 0.5 wt% of GO shows conductivity values 80 times higher than the neat epoxy.
