Abstract MXene has been widely used in energy storage, photocatalysis and lubrication area due to its good mechanical, electrical, and chemical properties. However, its friction and adhesion properties have not yet been fully grasped. In this study, for the first time, atomic force microscopy (AFM) Nanoman technology was used to compare the nano friction and adhesion of Ti3C2 and Nb2C MXene. The results indicated that the friction and adhesion of Nb2C were less than Ti3C2 under the same conditions, which is related to the difference in surface dipole moment density. In addition, adhesion and friction of both two MXenes decrease with the temperature increase. This study provides a broader application prospect for these new materials.

通过原子力显微镜研究 Ti3C2 和 Nb2C MXene 的纳米摩擦和粘附性能

摘要 MXene 因其良好的机械、电学和化学性能而被广泛应用于储能、光催化和润滑领域。然而，其摩擦和粘附性能尚未完全掌握。在这项研究中，首次使用原子力显微镜 (AFM) Nanoman 技术来比较 Ti3C2 和 Nb2C MXene 的纳米摩擦和附着力。结果表明，在相同条件下，Nb2C 的摩擦和附着力小于 Ti3C2，这与表面偶极矩密度的差异有关。此外，两种 MXenes 的附着力和摩擦力都随着温度的升高而降低。本研究为这些新材料提供了更广阔的应用前景。
