In this article, two different preparation methods were employed to explore the way to maximize the synergistic effect between polyimide (PI) and graphene (Gr) on the friction and wear of polytetrafluoroethylene (PTFE) composites. Results indicate that the incorporation of Gr into PI firstly is more beneficial for the improvement of tribological performance rather than the blending of Gr and PTFE...
In this paper, the role of debris in the formation of polytetrafluoroethylene (PTFE) film was investigated using the molecular dynamic simulation of debris adhesion. The results indicate that the internal structure of PTFE debris could not be changed easily because of the strong cohesion of PTFE debris. Debris will be adhered on Fe surface by the strong adhesion between Fe surface and debris. With...
