In the current invention, an improved graft polymerization method from general graphitic structures with organic based monomers through the mechanism of Reversible Addition- 1 Fragmentation Chain Transfer (RAFT) polymerization was developed. The present invention comprises of organic hybrid nanomaterials comprisingg graphitic structures covalently bonded via chemically reactive groups on the outer walls o~ the structure and methods for forming the covalently bonded structures to many organic based monomers and/or polymers through RAFT polymerization utilizing dithioester as a chain transfer agent. The present invention also comprises the nanocomposite formation of sue ~ organic hybrid nanomaterials with common plastic to form graphitic nanocomposite reinforced plastic articles.
