    摘要: An aggregate of carbon nanotubes has an acid adsorption amount equal to or greater than 0.6 mass % and equal to or less than 12 mass %, which is obtained by subjecting a starting material composition containing carbon nanotubes to a two-stage wet oxidation treatment. A method of producing an aggregate of carbon nanotubes includes a primary oxidation treatment step, wherein a starting material composition containing carbon nanotubes is subjected to a wet oxidation treatment to give a primary treated aggregate of carbon nanotubes having a ratio (G/D ratio) of the height of G band to that of D band in Raman spectroscopic analysis at 532 nm wavelength equal to or greater than 30; and a secondary oxidation treatment step of performing a wet oxidation treatment under an oxidizing condition stronger than that of the primary oxidation treatment step.

    摘要: A method for synthesizing carbon nanotubes (CNT) comprises the steps of providing a growth chamber, the growth chamber being heated to a first temperature sufficiently high to facilitate a growth of carbon nanotubes; and passing a substrate through the growth chamber; and introducing a feed gas into the growth chamber pre-heated to a second temperature sufficient to dissociate at least some of the feed gas into at least free carbon radicals to thereby initiate formation of carbon nanotubes onto the substrate.

    摘要: A method of removing metal impurities from carbon nanotubes includes treating carbon nanotubes with distilled bromine in a substantially oxygen- and water-free atmosphere and then removing the distilled bromine from the carbon nanotubes. Purified carbon nanotubes having an iron content from about 2.5 to about 3.5 by weight that are substantially free of derivatization at the ends and defect sites are made available via this method.
