Title (EN) METHOD OF MANUFACTURING DENSELY FITTED MULTI−LAYER CARBON NANO−TUBE
(FR) PROCEDE DE FABRICATION DE NANOTUBE EN CARBONE A COUCHES MULTIPLES AJUSTEES DE FAÇON DENSE
Abstract: front page image
(EN)A method of manufacturing, with high purity and high efficiency, a multi−layer carbon nano−tube (10) having layers densely fitted to the center part thereof, comprising the step of leading a carbon bar (2) into plasma flame (1) generated in the atmosphere of inert gas (4) added with hydrogen to evaporate carbon so as to stack the densely fitted multi−layer carbon nano−tube (10) on the surface of the carbon bar (2).
(FR)L'invention concerne un procédé de fabrication à pureté et rendement élevés d'un nanotube en carbone (10) présentant des couches multiples ajustées de façon dense sur leur partie centrale. Ce procédé comprend l'étape consistant à amener une barre carbone (2) dans une flamme plasma (1) générée dans l'atmosphère d'un gaz inerte (4) avec addition d'hydrogène, de manière à évaporer le carbone, afin d'empiler le nanotube en carbone à couches multiples (10) sur la surface de la barre carbone (2).
