Abstract
The graphene and graphene oxide have drawn much attention due to their excellent physical and chemical performances, as well as 2-dimension structure and high surface area. Herein, a facile method was proposed to prepare the graphene oxide and it was then introduced into epoxy to prepare nanocomposites. Results showed that the dielectric constant of the epoxy/graphene oxide nanocomposite was decreased by adding only 0.2 wt% of the fillers, while the dielectric loss stayed at a low level. Meanwhile, the glass-transition temperature of the nanocomposite was increased to 90.3 °C from 74.9 °C for the pure epoxy. Moreover, the thermal decomposition temperature (at 5% weight loss) of the nanocomposite was also increased greatly. Based on these results, we suggested that the graphene oxide was a promising additive for preparing low-κ epoxy nanocomposites with high properties.
