## Abstract

With the rapid advancements in industrial technology, the demand for high-performance lubrication has surpassed the capabilities of traditional solid or liquid lubricants. In this study, a novel MXene-based solvent-free lubricating nanofluid was developed through the surface functionalization of Ti3C2Tx MXene nanosheets. This innovative material combines the superior mechanical properties of solid Ti3C2Tx MXene nanosheets with the stable flow and rapid self-repairing capabilities of liquid lubricants. The successful synthesis of the MXene-based solvent-free nanofluid lubricant was confirmed through a series of characterization techniques, and it was demonstrated that this nanofluid maintained excellent flowability at room temperature. Subsequent tribological tests revealed that the friction coefficient and the wear performance of the MXene-based solvent-free nanofluid lubricant improved with increasing mass concentrations of Ti3C2Tx MXene nanosheets under consistently applied loads. These results indicate that the MXene-based solvent-free nanofluid lubricant significantly reduces friction and wear, showcasing its potential as a high-performance lubricant for industrial applications.
