▎ 摘  要

NOVELTY - Graphene reinforced polyethylene terephthalate composition includes a polyethylene terephthalate monomer, and 0.005-0.3 wt.% graphene nanoplatelets in the form of one or more layers of two-dimensional mono-atomic carbon sheets. USE - Graphene reinforced polyethylene terephthalate composition. ADVANTAGE - The graphene reinforced polyethylene terephthalate composition has graphene nanoplatelets, that may be uniformly dispersed in PET so as to provide reinforced bulk PET. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene reinforced polyethylene terephthalate (PET), which involves adding graphene nanoplatelets to a solvent suitable for producing PET, sonicating the solvent and graphene nanoplatelets to cause a homogeneous dispersion of the graphene nanoplatelets within the solvent, centrifuging the solvent and graphene nanoplatelets to remove larger graphene nanoplatelets that are not suitably dispersed within the solvent, decanting a supernatant solution of graphene nanoplatelets dispersed in the solvent, and performing a reaction to produce a PET monomer.
