Abstract (en)
[origin: FR2882047A1] The concentration of sodium hypochlorite is 1-10 wt.% at lower or equal to 60[deg]C for up to 24 hours. Acidification is carried out until the medium has pH lesser than 5, when the hypochlorite concentration exceeds 3-4%. The carbon nanotubes having the atomic ratio of oxygen/carbon is equal or higher than 5% and the solvent is miscible with water.
