▎ 摘　　要

NOVELTY - Highly conductive nanocomposite comprises organically modified montmorillonite/polylactic acid nanocomposite particles, and graphene that is coated on the surface of organically modified montmorillonite/polylactic acid nanocomposite particles. USE - Highly conductive nanocomposite used as three-dimensional printing material (claimed). ADVANTAGE - The highly conductive nanocomposite has excellent mechanical properties, high thermal conductivity and high electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing highly conductive nanocomposite, which involves: (A) preparing an organically modified montmorillonite/polylactic acid; (B) ultrasonically dispersing graphene in an organic solvent to obtain a graphene dispersion; and (C) mixing the graphene dispersion and the organically modified montmorillonite/polylactic acid nanocomposite particle suspension, and heating to 120-150 degrees C to obtain highly conductive nanocomposite. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph of the graphene micro sheet.
