▎ 摘　　要

NOVELTY - Composite particle comprises inorganic particles and graphene oxide particles which cover at least a part of the inorganic particles, where the surface of the graphene oxide particles is modified graphene oxide particles modified with a hydrocarbon group which may have a substituent. USE - The composite particle is used as inorganic fillers for resin compositions, and magnetic materials, electrode active materials for batteries, dielectric materials, and piezoelectric materials, depending on type of inorganic particles. ADVANTAGE - The composite particle has excellent insulation and thermal conductivity, excellent dispersibility and high heat resistance.
