▎ 摘　　要

NOVELTY - An electrically conductive composite material comprises carbon nanotubes and 0.005-0.06 wt.% graphene nanoplatelets within polymer matrix in which carbon nanotubes have average length of greater than or equal to 10 mu m. USE - An electrically conductive composite material used as mixture for electrically conductive composite used for article (all claimed). ADVANTAGE - Electrical conductivity is improved by adjusting composition of polymer composites reinforced with conductive fillers. Conductive composite material costs low and is light weight and easy to process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) mixture comprising carbon nanotubes and 0.005-0.06 wt.% graphene nanoplatelets within resins in which carbon nanotubes have average length of greater than or equal to 10 mu m; (2) electrically conductive composite material comprising mixture and reinforcing phase; (3) article comprising electrically conductive composite material; and (4) composite production which involves preparing mixture and subjecting mixture to high shear mixing process.
