The process for manufacturing carbon nanotubes with metallic core of nanometric or micrometric dimensions, comprises supplying metallic fibers (3) on a conductor substrate (2), ionically implanting amorphous carbon on or under a surface of the metallic fiber, thermally treating the carbon in the supply zone thus continuously covering the metallic fiber using carbon sheets having symmetry sp2, and removing the residual amorphous carbon. The supply zone comprises the substrate and the metallic fibers. The substrate comprises a layer of metal catalyst in its surface. The process for manufacturing carbon nanotubes with metallic core of nanometric or micrometric dimensions, comprises supplying metallic fibers (3) on a conductor substrate (2), ionically implanting amorphous carbon on or under a surface of the metallic fiber, thermally treating the carbon in the supply zone thus continuously covering the metallic fiber using carbon sheets having symmetry sp2, and removing the residual amorphous carbon. The supply zone comprises the substrate and the metallic fibers. The substrate comprises a layer of metal catalyst in its surface. The metal catalyst and a solid solution are deposited in the surface of the supply zone before supplying the carbon. The carbon compound undergoes a catalytic decomposition during the thermal treatment. The fiber metal has a conductivity higher than a metal solution with carbon. Monopore or multipore (7) membranes are produced on the substrate. Electrolysis is carried out to grow each fiber in the membrane pores. A mask is produced in an electrically insulating membrane for localization or selection of pores of the membrane. The membrane is aluminum, and the pores are produced in the membrane by aluminum anodization. |
