▎ 摘　　要

NOVELTY - Method for preparing a composite adhesive, involves uniformly mixing a dispersion liquid, an acrylic acid derivative polymer solution and graphene nanoplatelets, adding azobisisobutyronitrile, and dispersing and ultrasonically treating to obtain the product. USE - The method is used for preparing a composite adhesive (claimed). ADVANTAGE - The composite adhesive combines the adhesiveness of the adhesive with the thermal conductivity of graphene, and has a thermal conductivity of 19-30 times compared with the thermal conductivity of the acrylic adhesive without adding graphene nanoplatelets.
