▎ 摘  要

NOVELTY - The production method of graphene conductive masterbatch involves: (S1) dissolving antistatic agent in organic solvent to obtain solution; (S2) ultrasonically dispersing graphene in organic solvent, then adding solution obtained in step (S1) under mechanical stirring, and concentrating resulting mixture to remove organic solvent and to obtain paste; and (S3) heating and melting paste obtained in step (S2), and dripping molten paste via falling material, and cooling. The antistatic agent comprises oleamide, erucamide, stearamide, or pentaerythritol stearate. USE - The method is useful for producing graphene conductive masterbatch, which is useful in formation of spinodal phase-separation morphology of highly efficient conductive network application (all claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene conductive masterbatch prepared by the above method; and (2) use of graphene conductive masterbatch in the formation of spinodal phase-separation morphology of highly efficient conductive network application.
