  • Patent number: 8784695
    Abstract: Disclosed herein is a method of manufacturing a nanocomposite using expanded graphite. The method is characterized in that monomers are formed into a polymer between the plate-shaped layers of the expanded graphite, and the polymer is intercalated therebetween, so that the plate-shaped layers of the expanded graphite are completely exfoliated or are formed into graphene, with the result that the expanded graphite is completely dispersed in a polymer matrix. The nanocomposite manufactured by this method has excellent electrical conductivity and thermal conductivity because the expanded graphite is uniformly dispersed in this nanocomposite.
