Graphene reinforced polyethylene terephthalate |
| abstract |
Compositions and methods for graphene reinforced polyethylene terephthalate (PET) are provided. Graphene Nanoplatelets (GNPs) comprising multi-layered graphene are used to enhance PET, thereby improving the properties of PET for various new applications. A masterbatch comprising polyethylene terephthalate with dispersed graphene nanoplatelets was obtained by mixing. The masterbatch is used to form PET-GNP nanocomposites at a weight fraction of 0.5% to 15%. In some embodiments, the PET and GNPs are melt mixed by twin screw extrusion. In some embodiments, ultrasound is combined with a twin screw extruder to aid in melt mixing. In some embodiments, the PET-GNP nanocomposite is prepared by high-speed injection molding. The PET-GNP nanocomposites were compared by their mechanical, thermal and rheological properties to compare different mixing methods. |
