Abstract

See full text

A corrosion-resistant dry film lubricant composition includes a lubricating pigment, a binder, and a solvent. The lubricating pigment comprises graphene platelets and is dispersed in the binder, and the solvent solubilizes the lubricant pigment and the binder. The graphene platelets are oxidized and functionalized with a silane. A method of producing a corrosion-resistant lubricant includes oxidizing exfoliated graphene to produce oxidized graphene platelets, functionalizing the oxidized graphene platelets with a silane to produce functionalized graphene platelets, and dispersing the functionalized graphene platelets in a lubricant composition, wherein the lubricant composition comprises a binder and a solvent.
