▎ 摘  要

NOVELTY - Composition of matter comprises: mono-facial polymer-grafted graphene particle, where a first side of the graphene particle comprises a grafted polymer; and aqueous-based drilling fluid. USE - The composition is useful for lubricating a tool surface (claimed). ADVANTAGE - None given. DETAILED DESCRIPTION - INDEPENDENT CLAIMs are also included for: method of lubricating a tool surface, comprising providing an aqueous-based drilling fluid, the aqueous-based drilling fluid having a mono-facial polymer-grafted graphene particle, where a first side of the graphene particle comprises a grafted polymer, and introducing the aqueous-based drilling fluid into a wellbore such that it contacts a tool surface to form a coated tool; and an apparatus comprising a drilling tool having a mono-facial polymer-grafted graphene particle adhered to a surface of the drilling tool.
