Abstract:
A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets comprising a suitable initial surface area are added to a solvent for producing PET. In some embodiments, the solvent comprises ethylene glycol. The solvent and graphene nanoplatelets are sonicated to disperse the nanoplatelets within the solvent. The solvent and graphene nanoplatelets are centrifuged to remove nanoplatelet agglomerates within the solvent. A supernatant solution of dispersed graphene nanoplatelets and solvent is decanted and then used for in-situ polymerization of the graphene reinforced PET comprising a continuous matrix of PET with a dispersed graphene reinforcement phase. The graphene reinforcements comprise a minimal number of layers of two-dimensional mono-atomic carbon sheets. In some embodiments, the number of layers ranges between 1 layer and 7 layers. The graphene reinforced PET preferably comprises a concentration of graphene nanoplatelets being less than substantially 2% weight fraction of the graphene reinforced PET.

Abstract:
The present invention provides a composite obtained by processing a resin composition including a thermoplastic resin, multi-walled carbon nanotubes, and a reinforcing material. The multi-walled carbon nanotubes have an average diameter of 10 nm or more and an I d /I g of 1 or less. The walls of the multi-walled carbon nanotubes consist of 10 or more layers of graphene. The rate of residual length of the carbon nanotubes present in the composite is 40% or more. The composite has improved mechanical properties without deterioration of conductivity. Due to these advantages, the composite can be used to manufacture various molded articles.
