Achieving macroscale superlubricity of van der Waals (vdW) nanopowders is particularly challenging, due to the difficulty in forming ordered junctions before friction and the friction‐induced complex contact restructuration among multiple nanometer‐sized junctions. Here, a facile way is reported to achieve vdW nanopowder‐to‐heterojunction conversion by graphene edge‐oxygen (GEO) incorporation. The...
Macroscale superlubricity breakdown of lubricating materials caused by substrate surface roughening and mechanochemical modification poses great challenges for their practical tribological applications. Here, a facile way is reported to access robust macroscale superlubricity in a vacuum environment, via the operando formation of graphene/transition‐metal dichalcogenide (TMDC) heterostructures at...
