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...
Graphene oxide (GO) water solution has been added and mixed to epoxy resin. Water has been evaporated at low pressure and the resulting mixture has been cured through an amine. Heating GO-epoxy samples at 130 °C in situ chemical reduction of GO has been carried out. Dielectric constant of these graphene-based samples shows an increase of more than 50% compared to neat epoxy even for 0.3 wt% of GO...
