Zr-MOFs (UIO-66-NH<sub>2</sub>)@Fluorinated Graphene for Developing Highly Antiwear, Friction-Reduction Lubricating Additives
Fluorinated graphene (FG) among numerous two-dimensional materials has enormous potential in improving antifriction properties. However, they being susceptible to thermal oxidation and prone to wear hinder practical applications. Herein, UIO-66-NH<sub>2</sub> (Zr-MOF) enjoying good chemical and thermal stabilities was assembled on the surface of FG nanosheets under covalent bonds and van der Waals forces. The Zr-MOF@FG composite was successfully synthesized and used as a lubricant additive. It can be seen that Zr-MOF@FG composites offer a synergistic lubricant mechanism at the friction interface. Moreover, due to the adsorption and purification performance of Zr-MOF, the obtained Zr-MOF@FG composite adsorbs the abrasive rust during the friction process, thereby realizing the purification of the lubricant. These findings suggest that Zr-MOF@FG shows tremendous potential as a lubricant additive.
