A novel tribofilm is created comprising multilayers of graphene with nanoparticles of zinc oxide and a polymeric binder as a solid-state lubricant for friction and wear reduction under extreme load conditions. Significantly improved tribological performance was measured under ambient conditions using a ball-on-disk tribometer with contact pressures up to 1.02 GPa. The graphene-rich lubricant demonstrates more than 80 % friction and wear reduction compared to unlubricated sliding. The resilience of this new adhesive coating suggest exceptional potential as a dry lubricant for high load-bearing applications.
