Nano friction and adhesion properties on Ti3C2 and Nb2C MXene studied by AFM

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.

Automated summary

This study compared the nano friction and adhesion of Ti3C2 and Nb2C MXene for the first time using AFM Nanoman technology, and found that Nb2C exhibited lower friction and adhesion properties than Ti3C2 under the same conditions, which is related to the difference in surface dipole moment density. Additionally, the adhesion and friction of both MXenes decreased with increasing temperature, providing broader application prospects for these new materials.
