Abstract: A sheet molding compound (SMC) is provided with superior conductivity properties based on the use of graphitics. A process for exfoliation of GnP and turbostratic carbon is also provided. By exfoliating the graphitics, a reduced amount of material can confer comparable properties relative to native GnPs or turbostratic carbon thereby reducing the amount of material usage, but also reducing negative effects to the base resin formulation through inclusion of these additives. Particular utility is found in thermoset resin molding to produce articles that are amenable to electrostatic coating and other surface treatments that rely on surface conductivity and especially in the realm of vehicle body parts.

Abstract: A monomer is provided for a thermoset molding compound. The monomer is also polymerized with conventional monomers to form thermoplastic polymers. Graphene oxide is used to chelate metal ions to form a graphene oxide chelate that is coupled to a monomer retaining an aliphatic unsaturation capable of free radical polymerization reaction. Inclusion of a metal ion chelated to the graphene oxide affords control over the conductivity of the resultant article. In some embodiments, the monomer is found polymerized into a resulting article proximal to the article surface.
