▎ 摘　　要

NOVELTY - Manufacturing graphene comprises reforming graphene, adding 6-30C fatty acid of the epoxy ring cleavage reaction catalyst in a presence of solvent with hydrophobicity, dispersing obtained graphene into the solvent, and dispersing and reacting the graphene. USE - The method is useful for manufacturing graphene, which is useful in nano-composite material (claimed). ADVANTAGE - The method allows economical manufacture of the graphene with high efficient and high thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nano-composite material comprising polymer having graphene powder (0.1-15 pts.wt.), nonpolar high molecule and nonpolar low melting point crystalline matter (100 pts.wt.).
