ABSTRACT

In this work, nanocomposites of epoxy resin and chemically reduced graphene oxide (RGO)were prepared by thermal curing process. X-ray diffractions confirmed the microstructuralproperties of RGO. Differential scanning calorimetry was used to evaluate the curing behaviorsof RGO/epoxy nanocomposites with different RGO loading amounts. We investigatedthe effect of RGO loading amounts on the mechanical properties of the epoxy nanocomposites. It was found that the presence of RGO improved both flexural strength and modulus ofthe epoxy nanocomposites till the RGO loading reached 0.4 wt%, and then decreased. Theoptimum loading achieved about 24.5 and 25.7% improvements, respectively, comparedto the neat-epoxy composites. The observed mechanical reinforcement might be an enhancementof mechanical interlocking between the epoxy matrix and RGO due to the uniqueplanar structures.
