Multi-layer graphene (MLG) filled poly(vinyl chloride) (PVC) composites were prepared by using conventional melt-mixing methods in order to improve tribological performance of rigid PVC. We investigated microstructure, microhardness, friction coefficient, and wear resistance of the MLG/PVC composites in details. We found that the presence of MLG could greatly decrease friction coefficient and wear rate of the MLG/PVC composites, implying higher wear resistance and tribological performance of the nanocomposites compared with neat PVC. Moreover, the wear mechanism of the MLG/PVC composites was also presented. Such high tribological performance of the MLG/PVC composites is mainly attributed to enhanced toughness of the MLG/PVC composites and high self-lubricant performance of the MLG. In light of its high tribological performance, the MLG/PVC composites have great potential to be used as wear-resistant materials in many fields.
