Abstract

A method for forming a dispersion includes mixing graphene particles, a fluorosilane coupling agent and a first solvent to produce a first dispersion wherein the graphene particles are from about 0.1 to about 0.8 weight percent of the first dispersion. The method includes concentrating the first dispersion by removing the first solvent to produce a second dispersion wherein the graphene particles are from about 2.0 to about 10.0 weight percent of the concentrated dispersion. The concentrated dispersion is mixed with a fluoropolymer dispersion including a second solvent, a surfactant, and fluoropolymer particles wherein the fluoropolymer dispersion has a solids content of about 30 weight percent to about 50 weight percent to form a second dispersion. A polymer binder in a third solvent is mixed with the second dispersion to form the coating dispersion.
