Preparation and Properties of Graphene / Poly (Ethylene Terephthalate) Composite Fibers

Abstract:

A novel nanocomposite fibers were prepared from poly (ethylene terephthalate) (PET) and reduced graphene oxide (rGO) via melt spinning and their thermal and mechanical properties were investigated. Graphite oxide and rGO were characterized by the Fourier transform infrared spectroscopy (FT-IR). FT-IR spectrum of GO and rGO showed the same peak of O-H stretching of the hydroxyl and C=C stretching of aromatic rings as well as C-O stretching. The thermal stability of pristine PET and rGO/PET composite masterbatch was characterized by the thermogravimetric analysis (TGA). The thermal degradation temperature of PET and rGO/PET nanocomposite masterbatch was found at 413.9 °C and 418.1 °C, respectively. The mechanical properties of rGO/PET nanocomposite fibers were investigated and it was found that the mechanical properties were improved in all aspects comparing with neat PET fiber, including tensile strength, young's modulus and elongation at break.
