• Abstract: In the present review, the current status of the intrinsic mechanical, thermal and physical properties of bulk graphene oxide (GO) and chemically modified graphene oxide (mGO) unsaturated polyester nanocomposites (UPNs) is thoroughly examined. The importance of Raman spectroscopy, X-Ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) in this review is clearly exhibited. Besides, the review to cover relevant knowledge about the UPNs and GO that are present in literature so far. Furthermore, the manufacture strategies of bulk graphene-based nanocomposites are discussed based on what has been reported in the literature. In addition, GO based UPNs have disclosed good performance related to mechanical properties and thermal stability and researchers have found optimal loadings that provide a novel material without agglomeration of the nanofillers. In particular, for the UPNs the presence of mGO at very low loadings can provide significant reinforcement to the final material, in terms of mechanical and thermal stability. An outstanding attainment have been observed for a group of researchers in terms of electrical conductivity of UPN/mGO nanocomposites. Finally, the potential applications and future perspectives are discussed with regard to scale up capabilities and possible developments for the novel material.
