Abstract: Epoxy nanocomposites containing thermally reduced graphene oxides (TRGs) with different oxygen contents were prepared and their mechanical and thermal properties were investigated. It was found that increasing the number of oxygen containing groups on the TRGs resulted in reduced agglomeration of the graphene oxides within the epoxy matrix. Therefore, in samples with a higher oxygen content, a higher interfacial contact area is present between the organic and inorganic phases in the nanocomposite, and so improvements in the storage modulus, break stress, yield stress, thermal decomposition temperature, glass transition temperature, and thermal conductivity were observed.
