What is claimed is: 1. A composite comprised of an effective amount of: a) substantially crystalline graphitic nanofibers consisting essentially of at least one uninterrupted, unbroken, substantially graphite sheet that is aligned substantially parallel to the longitudinal axis of the nanofiber and
What is claimed is: 1. A composite comprised of an effective amount of: a) substantially crystalline graphitic nanofibers consisting essentially of at least one uninterrupted, unbroken, substantially graphite sheet that is aligned substantially parallel to the longitudinal axis of the nanofiber and which has a substantially non-cylindrical multifaceted tubular structure, wherein when two or more of said sheets is present they are present is a tube within a tube structure and wherein the distance between graphite sheets is from about 0.335 nm to about 0.67 nm, wherein said substantially crystalline graphitic nanofiber has a crystallinity greater than about 95%; and b) a polymeric material. 2. The composite of the claim 1 wherein the distance between the graphite sheets is from about 0.335 and 0.40 nm. 3. The composite of claim 1 wherein at least a portion of the edge regions of the nanofiber contain a functional group selected from the group consisting of basic groups, acidic groups, and oxygenated groups. 4. The composite of claim 3 wherein the functional group is a basic group that is a NH4+ group. 5. The composite of claim 3 wherein the functional group is an acid group which is a COOH- group. 6. The composite of claim 3 wherein the functional group is an oxygenated group selected from the group consisting of hydroxyl, peroxide, ether, keto, and aldehyde. 7. The composite of claim 1 wherein the polymeric material is a synthetic polymeric resin selected from the group consisting of nylons, polyethylene, polypropylene, polyvinyl chloride, styrenics, polyurethanes, polyimides, polycarbonates, polyamides, polyethylene terephthalate, polytetrafluoroethylene, acrylics, phenolics, unsaturated polyesters. 8. The composite of claim 1 wherein the polymeric material is a polymer from a natural source and is selected from the group consisting of cellulose, gelatin, chitin, polypeptides, polysaccharides, or other polymeric materials of plant, animal, or microbial origin. 9. The composite of claim 1 which is in the form of a fiber, cylinder, plaques, film, coating, sheet or extruded shape.
