Toward Macroscale Superlubricity with 2D Materials

Friction and wear-related failures remain the greatest problems in today’s moving mechanical components, from microelectromechanical devices to automotive assemblies and to biological systems. The critical need to reduce and eliminate the tribological failures constitutes  the necessity for continuous search of novel materials and lubrication solutions. In this presentation, we overview recent advances in  establishing the fundamental understanding of materials interactions at sliding interfaces and use this knowledge as a guide to developing 2D material-based solutions that enhance reliability and efficiency of tribological systems. We highlight recent progress in implementing 2D materials for friction reduction to near-zero values—superlubricity—across scales from nano- up to macroscale contacts. Overall, the findings have not only allowed us to solve some long-standing puzzles, but could also open a new avenue for the development of new concepts and design strategies for next generation of tribologically efficient materials systems.
