dc.description.abstract© 2020 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimIn 2019 Ferreira et al. observed for the first time the influence of the superlubricity phenomenon of platelet-like fillers on the properties of high molecular weight polyethylene (HMWPE) in the molten state. At the time, the study was carried out in the solid state of the polymer, analyzing the influence of the superlubricity phenomenon of oxide graphene and oxide graphite (GrO) agglomerates on the mechanical properties of the HMWPE. It was observed that the agglomerates, due to their superlubricity state, toughen the HMWPE polymer matrix. Here, mechanical tests (tensile), X-ray microtomography, and scanning electron microscopy are carried out to elucidate this phenomenon. The same is observed for polystyrene containing very poorly dispersed GrO. The results presented here are a paradigm shift, as it has always been thought that the presence of agglomerates is harmful, but the opposite is proven here. In general, this paper can contribute a lot to the development of new composites and nanocomposites based on fillers that present the superlubricity phenomenon.
