Graphene is the material with the best mechanical resistance ever encountered. Various types of studies have been carried out on possible applications. The use as a reinforcement in nanocomposites has shown to be a promising field, but some studies indicate that the graphene oxide (GO) and reduced graphene oxide (RGO) have better results as reinforcement, due to the functional groups, which allow a better adhesion with the matrix. This study analyzes the production of polypropylene (PP) nanocomposite comparing the use of graphene oxide (GO) and reduced graphene oxide (RGO) as fillers and irradiated polypropylene as a coupling agent. A twin-screw extruder and injection molding machine were used to produce the nanocomposite PP reinforced with 0.2 wt. % of GO and RGO by melt blending. The GO and RGO were characterized by XRD analysis. The nanocomposite samples were characterized by XRD, SEM, TG, DSC and mechanical test.
