摘要

In recent years, nanoparticle additives have been frequently used to enhance the tribological properties of polymers, especially in the biopolymer system. In this study, we analyzed the tribological behavior and energy dissipation properties of MoS2 and nano-copper-reinforced biopolymer hydroxypropyl methylcellulose (HPMC) composites. The tribological behavior of the composite was evaluated at low load using a ball-on-disk cycle tester. The addition of MoS2 and nano-copper additives improved the wear resistance and reduced the friction coefficient of the HPMC composites. The addition of both MoS2 and copper additives had a synergistic effect on enhancing the tribology behavior. The dissipation energy results indicated a linear correlation between wear and energy consumed. This study suggests that the wear mechanism varies with the type and quantity of additive, regardless of the normal load applied.
