  • Nanocarbon solubilizer, method for purifying same, and method for producing high-purity nanocarbon
    Patent number: 7691358
    Abstract: A water solubilizer for nanocarbons contains a surfactant which can form a spherical micelle vesicle having a diameter of 50-2,000 nm in a water solution or a water-soluble polymer having a weight-average molecular weight of 10,000-50,000,000 as an active constituent. For example, the water solubilizer is used for purification of nanocarbons.
