NOVELTY - A polymer nanocomposite comprises a matrix comprising polyethylene terephthalate, and a reinforcement material comprising dispersed phase graphene nanoplatelets. USE - Polymer nanocomposite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene reinforced polyethylene terephthalate, which involves obtaining graphene nanoplatelets comprising a suitable surface area, adding the graphene nanoplatelets to a dispersion medium suitable for producing polyethylene terephthalate, sonicating the dispersion medium and graphene nanoplatelets so as to cause a homogeneous dispersion of the graphene nanoplatelets within the dispersion medium, centrifuging the dispersion medium and graphene nanoplatelets to remove a portion of larger graphene nanoplatelets that are not suitably dispersed within the dispersion medium, decanting a supernatant solution of graphene nanoplatelets dispersed in the dispersion medium, and utilizing the supernatant solution for polymerization of the graphene reinforced polyethylene terephthalate.
