Significantly Enhanced Tribological Properties of PTFE/PEEK Fabric Composites by Macroporous Metal−Organic Frameworks with Solid–Liquid Synergistic Lubrication

In this work, a macroporous oil-containing metal-organic framework material (CuBTCO) was prepared by a solvothermal method and vacuum impregnation. The tribological behaviors of PTFE/PEEK fabric composites (PFC) filled with CuBTCO were evaluated by the pin-on-disk tribometer under different loads. The coefficient of friction and mass wear rate of PFC containing 6 wt% CuBTCO (PFC-CuBTCO-6%) were 0.017 and 1.1×10-9 g/(Nm), respectively, which were reduced by 63.8% and 76.3% in comparison to PFC containing 6 wt% CuBTC under the same conditions. The excellent tribological properties of PFC-CuBTCO-6% are attributed to the solid–liquid synergistic lubrication between the adsorption film formed by the oleylamine released from CuBTCO and the PTFE-based transfer film. This work provides a novel approach for the structural design of solid–liquid synergistic lubrication of fabric liner composites.
