Hi!

Have a look at this patent: "Coatings containing functionalized graphene sheets and articles coated therewith" (Preferred binders are polymeric binders. Polymeric binders can be thermoplastics or thermosets and may be elastomers. Binders may also comprise monomers that can be polymerized before, during, or after the application of the coating to the substrate. Polymeric binders may be cross-linked or otherwise cured after the coating has been applied to the substrate. Examples of preferred polymeric binders include polyethers such as poly(ethylene oxide)s (also known as poly(ethylene glycol)s, po!y(propylene oxide)s (also known as poly(propylene glycol)s, and ethylene oxide/propylene oxide copolymers, cellulosic resins (such as ethyl cellulose, ethyl hydroxyethyl cellulose, carboxymethyl cellulose, cellulose acetate, cellulose acetate propionates, and cellulose acetate butyrates), and polyvinyl butyral, polyvinyl alcohol and its derivatives, ethylene/vinyl acetate polymers, acrylic polymers and copolymers, styrene/acrylic copolymers, styrene/maleic anhydride copolymers, isobutylene/maleic anhydride copolymers, vinyl acetate/ethylene copolymers, ethylene/acrylic acid copolymers, polyolefins, polystyrenes, olefin and styrene copolymers, epoxy resins, acrylic latex polymers, polyester acrylate oligomers and polymers, polyester diol diacrylate polymers, UV- curable resins, and polyamide, including polyamide polymers and copolymers (i.e., polyamides having at least two different repeat units) having melting points between about 120 and 255 0C (such as those sold under the trade names Macromelt by Henkel and Versamid by Cognis).

A nice review on graphene functionalization: "Functionalization of Graphene: Covalent and Non-Covalent Approaches, Derivatives and Applications" [2]

Hope that helps

I will definitely take a look on the patent you sent me! Thank you very much for your time and help!
