Abstract
A method of reinforcing a polymeric material with carbon nanofibers is provided in which carbon nanofibers are combined with a polymer and a solvent for the polymer to form a substantially homogeneous mixture, followed by removal of the solvent by evaporation or coagulation. The resulting conductive polymeric nanocomposite material exhibits high electrical and thermal conductivity, enhanced mechanical strength, abrasion resistance, and dimensional stability.
Claims6
A conductive polymeric nanocomposite material having vapor grown carbon nanofibers incorporated therein, said nanocomposite material formed by providing vapor grown carbon nanofibers, combining said nanofibers with a solvent to form a solution mixture, adding a polymer selected from the group consisting of polyurethanes, polyimides, epoxy resins, silicone polymers, and aromatic-heterocyclic rigid-rod and ladder polymers to said solution mixture to form a substantially homogeneous solution mixture, and removing said solvent from said substantially homogeneous solution mixture.
