Tribological systems are an integral part of any moving mechanical assembly, from nanoscale microelectromechanical systems to macroscale automotive and aerospace applications. Minimizing friction and wear-related mechanical failures remains one of the greatest challenges in today’s moving mechanical systems. We have prepared a graphene-based superlubricity solution which, when applied which to the surface of interest during sliding in a dry nitrogen atmosphere, dramatically reduces friction and wear of the system to near-zero values. The phenomenon originates from formation of graphene nanoscrolls, which act as nanoscale ball bearings between the two contact surfaces.
