Tribological Behaviour of POM Reinforced By Graphene and PTFE

Graphene/polytetrafluoroethylene (PTFE)/polyoxymethylene (POM) composites were successfully prepared by high speed mixer and injection molding machine. As a consequence, graphene and PTFE covered at the surface of the POM powder evenly and the tribological performance of the composites is enhanced remarkably, especially the graphene content is 0.2%. In addition, the friction and wear behaviour of the composites is connection to the content of graphene, both of them will decrease at first and increase with the adding of graphene. In a word, this proposed method is simple and effective for mass production of graphene/PTFE/POM composites, and it is promising to be applied to fabricate many kinds of nanofillers modified POM composites.
