the present invention relates to fullerene , nanotube , or nanofiber filled metals and polymers . this invention stems from a cross - disciplinary combination of electromagnetic and acoustic processing and property enhancement of materials through fullerene or nanofiber additives . containerless processing in the form of electromagnetic field enduced and / or acoustic mixing leads to controlled dispersion of fullerenes , nanotubes , or nanofibers in various matrices . the invention provides methods of mixing that highly disperse and align the fullerenes , nanotubes , or nanofibers within the matrices of metals and polymers . the invention provides new compositions of matter and multifunctional materials based on processing , composition , and degree of in situ processing .
