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.
