摘要： A p-type semiconductor carbon nanotube and a method of manufacturing the same are provided. The p-type semiconductor carbon nanotube includes a carbon nanotube; and a halogen element that is attached to an inner wall of the carbon nanotube and accepts electrons from the carbon nanotube to achieve p-type doping of the carbon nanotube. The p-type semiconductor carbon nanotube is stable at high temperatures and can maintain intrinsic good electrical conductivity of the carbon nanotube. The p-type semiconductor carbon nanotube can be relatively easily obtained using a conventional method of manufacturing a carbon nanotube, thereby significantly broadening the range of application of the carbon nanotube to electronic devices.

摘要： Metal loaded carbon filaments and a process for making the same are provided. This process includes forming metal on carbon filaments produced from at least one carbon-containing compound, e.g., an alkane or an alkene. The metal may be formed on surfaces of previously formed carbon filaments by, for example, electroplating, impregnation, or chemical vapor deposition. Alternatively, the carbon filaments and the metal may be formed concurrently, resulting in the metal being incorporated in the carbon filaments. An article of manufacture is also provided that includes a carbon filament having metal disposed thereon. The article of manufacture may be, for example, a high surface area catalyst, an electronic element, and a composite material having enhanced electrical properties.

摘要： This invention is directed to making chemical derivatives of carbon nanotubes and to uses for the derivatized nanotubes, including making arrays as a basis for synthesis of carbon fibers. In one embodiment, this invention also provides a method for preparing single wall carbon nanotubes having substituents attached to the side wall of the nanotube by reacting single wall carbon nanotubes with fluorine gas and recovering fluorine derivatized carbon nanotubes, then reacting fluorine derivatized carbon nanotubes with a nucleophile. Some of the fluorine substituents are replaced by nucleophilic substitution. If desired, the remaining fluorine can be completely or partially eliminated to produce single wall carbon nanotubes having substituents attached to the side wall of the nanotube. The substituents will, of course, be dependent on the nucleophile, and preferred nucleophiles include alkyl lithium species such as methyl lithium. Alternatively, fluorine may be fully or partially removed from fluorine derivatized carbon nanotubes by reacting the fluorine derivatized carbon nanotubes with various amounts of hydrazine, substituted hydrazine or alkyl amine. The present invention also provides seed materials for growth of single wall carbon nanotubes comprising a plurality of single wall carbon nanotubes or short tubular molecules having a catalyst precursor moiety covalently bound or physisorbed on the outer surface of the sidewall to provide the optimum metal cluster size under conditions that result in migration of the metal moiety to the tube end.

摘要： A plurality of processes for producing unique end products containing elemental metals or metal oxides on and in a carbon substrate, elemental metals or metal oxides in the absence of such a carbon substrate, mixtures of elemental metals or metal oxides on and in a carbon substrate, or mixtures of elemental metals or metal oxides in the absence of such a carbon substrate, all of which processes involve the preparation of a first-step intermediate product that is a carbonaceous material appearing to be non-graphitic by X-ray diffraction standards and containing metal and halogen, which intermediate product is made from graphite fluoride and an appropriate metal halide. Among the end products are aluminum oxide fibers, elemental iron fibers, magnetic carbon fibers containing either iron or an iron-nickel alloy, and carbon containing various metals in the form of elemental metal or oxides.

摘要： STABLE CARBON MONOFLUORIDE HAVING A MAXIMUM SUPERSTOICHIOMETRIC FLUORING-TO-CARBON RATION AND CONTROLLED, REPRODUCIBLE METHODS FOR PREPARING STABLE CARBON MONOFLUORIDES INCLUDING CARBON MONOFLUORIDE FILMS ON VARIOUS SHAPES OF SOLID CARBON, BOTH AT ATMOSPHERIC PRESSURE AND AT SUPERATMOSPHERIC PRESSURES. THE PRIOR METHOD OR PREPARING CARBON MONOFLUORIDES AT ATMOSPHERIC PRESSURE BY REACTING FLUORINE AND GRAPHITE AT A TEMPERATURE IN THE RANGE FROM ABOUT 400* C, TO ABOUT 600* C, IS MADE REPRODUCIBLE BY CONTROLLING THE REACTION TEMPERATURE SO THAT IT DOES NOT VARY MORE THAN +3* C. STABLE SUPERSTOICHIOMETRIC CARBON MONOFLUORIDES CAN BE PREPARED AT ATMOSPHERIC PRESSURE BY REACTING CARBON AND FLUORINE AT A TEMPERATURE IN THE RANGE FROM ABOUT 620* C, TO ABOUT 635* C, AND MAINTAINING THE TEMPERATURE FOR SUCH A PERIOD OF TIME AS TO ALLOW THE REACTION TO GO SUBSTANTIALLY TO COMPLETION. APPROXIMATELY ONE TO THREE HOURS IS NEEDED AT TEMPERATURES IN THE RANGE TO FORM STABLE CARBON MONOFLUORIDE FILMS. AT TEMPERATURES BETWEEN ABOUT 624* C, AND ABOUT 630* C, A CARBON MONOFLUORIDE HAVING A MAXIMUM SUPERSTOICHIOMETRIC FLUORING-TO CARBON RATIO OF APPROXIMATELY 1.12/1.00 CAN BE PRODUCED. STABLE CARBON MONOFLUORIDES HAVING SUPERSTOCHIOMETRIC PROPORTIONS OF FLUORINE AND CARBON CAN ALSO BE PREPARED AT SUPERATMOSPHERIC PRESSURES, WITH THE ADDITION OF HEAT AT PRESSURES UP TO ABOUT 225 P.S.I.A. AND WITHOUT THE ADDITION OF HEAT AT PRESSURES BETWEEN ABOUT 225 P.S.I.S. AND ABOUT 250 P.S.I.A.
