▎ 摘 要
NOVELTY - Solid-state lubricant comprises graphene, an oxide of a metal, and a polymeric binder. USE - Solid-state lubricant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for making a solid-state lubricant coating on a substrate, which involves: (A) making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder; (B) coating a substrate with the homogeneous slurry; (C) drying the slurry on the substrate; and (D) resulting in a solid lubricant coating on the substrate.
