▎ 摘　　要

NOVELTY - Nanocarbon material dispersion composition comprises a dispersion medium and a nanocarbon material dispersed in the dispersion medium on a nanoscale, where the nanocarbon material comprises nanodiamond particles and a graphene layer formed on the surface of the nanodiamond particles, and the wavenumber corresponding to the peak top value within the wavenumber band of 1580± 50 cm-1in Raman spectrum is 1585-1630 cm-1, and has a peak at 2θ of 43-44° in X-ray diffraction analysis (XRD) analysis. USE - The nanocarbon material dispersion composition is used for film (claimed). ADVANTAGE - The nanocarbon material dispersion composition has excellent dispersibility in the dispersion medium while having a graphene structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a film comprising a base material and a coating of a nanocarbon material provided on the surface of the base material, where the film has a wave number of 1585-1630 cm-1corresponding to the peak top value in the wave number band of 1580± 50 cm-1in Raman spectrum, and a peak exists at 2θ of 43-44° in XRD analysis.
