Intrinsic Stiffness

This work shows the potential of binary blends composed of partially bio-based poly(ethyelene terephthalate) (bioPET) and fully bio-based poly(amide) 10,10 (bioPA1010). These blends are manufactured by extrusion and subsequent injection moulding and characterized in terms of mechanical, thermal and thermomechanical properties. To overcome or minimize the immiscibility, a glycidyl methacrylate copolymer, namely poly(styrene-ran-glycidyl methacrylate) (PS-GMA; Xibond™ 920) was used. The addition of 30 wt % bioPA provides increased renewable content up to 50 wt %, but the most interesting aspect is that bioPA contributes to improved toughness and other ductile properties such as elongation at yield. The morphology study revealed a typical immiscible droplet-like structure and the effectiveness of the PS-GMA copolymer was assessed by field emission scanning electron microcopy (FESEM) with a clear decrease in the droplet size due to compatibilization. It is possible to conclude that bioPA1010 can positively contribute to reduce the intrinsic stiffness of bioPET and, in addition, it increases the renewable content of the developed materials.

The Fourier Transform

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.
