▎ 摘  要

NOVELTY - A nanocarbon dispersion comprises a nanocarbon and rosin or its derivative as a dispersant. USE - Nanocarbon dispersion used in resin composition (claimed) for forming composite material. Uses include but are not solder paste flux, automobile cables, polyacrylonitrile-based carbon fiber blended products, rubber/resin composite materials, pressure sensors, transparent conductive films, high-frequency transistors, electric double layer capacitors, and lithium-ion battery negative electrode materials. ADVANTAGE - The nanocarbon dispersion provides the resin composition having excellent properties such as mechanical strength such as tensile strength, elastic modulus and thermal deformation temperature and electrical or thermal conductivity. The original physical characteristics of nanocarbon, such as degree of freedom in the dispersant type are maintained and the nanocarbon can be stably dispersed in water or other solvents. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of the nanocarbon dispersion, which involves mixing the nanocarbon and dispersant; (2) dispersion solubilization method for nanocarbon, which involves mixing the nanocarbon, dispersant, and a solvent as a dispersion medium; (3) resin composition, which comprises a resin component and the nanocarbon dispersion; and (4) dispersant, which comprises the rosin or its derivatives.
