▎ 摘  要

NOVELTY - Graphene reinforced polyethylene terephthalate (PET) composition comprises: a continuous matrix comprising PET; and a dispersed reinforcement phase comprising graphene nanoplatelets in the form of a minimal number of layers of two-dimensional mono-atomic carbon sheets. USE - The graphene reinforced PET composition is useful for preparing composite materials that are useful in packaging, automotive and aerospace applications. ADVANTAGE - The graphene reinforced PET composition: provides composite materials with improved mechanical, barrier and reinforcement properties, and improved strength and durability; and can be prepared by a method that is effective and reliable, uniformly disperses graphene nanoparticles in PET so as to provide reinforced bulk PET. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene reinforced PET, comprising: obtaining graphene nanoplatelets initially comprising a suitable surface area; adding the graphene nanoplatelets to a solvent suitable for producing PET; sonicating the solvent and graphene nanoplatelets so as 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 using the supernatant solution for in situ polymerization of the graphene reinforced PET.
