Abstract

Abstract: In this study, the effects of incorporating graphene oxide (GO) and γ irradiation on the mechanical and wear properties of ultra-high-molecular-weight polyethylene (UHMWPE) were investigated. Moreover, the crystallinity and oxidation index of irradiated GO/UHMWPE composites were studied. The results indicated that the crystallinity, compression performance, and hardness of UHMWPE were improved owing to the incorporation of GO and γ irradiation treatment. Furthermore, the incorporation of GO and γ irradiation treatment could effectively reduce the wear rate of UHMWPE. In addition, the incorporation of GO could improve the oxidative resistance of irradiated and aged UHMWPE.
