Definitions

  • Figure 37 is a graph illustrating modulus and strength of ultrasound processed nanocomposites with 2% GNP, according to the present disclosure
  • AHf is the heat of fusion
  • AH CC is the heat of crystallization (cold crystallization)
  • AH is the heat of fusion for 100% crystalline polymer
  • PET - 140.1 J/g is the heat of fusion for 100% crystalline polymer
  • vv is the weight fraction of the reinforcement phase in the nanocomposites.
  • Fig. 34 shows that the nanocomposites are tougher (area under the stress-strain curve) than PET.
  • the Young's modulus for the 2% nanocomposite was identical from the two different injection molding processes used (3.1 GPa). However, nanocomposite tubes with 2% GNP loading deviated in the type of failure with respect to lower weight fractions. At 2% GNP loading, nanocomposites exhibited only 1% strain which is significantly lower compared to failure strain for 1.2% GNP loading (400%).
  • Transmission micrographs were collected for nanocomposite tensile bars of 5% and 15% weight fraction. Even though there are few layered graphene, as shown in Figs. 56(a) and (b), transmission micrographs of the nanocomposites indicate that the graphene nanoplatelets are not completely exfoliated in the PET matrix. Micrographs shown in Figs. 55(a) and (b) indicate that the nanoplatelets are distributed in the matrix, with regions of high concentration.
  • Raman spectrum for PET and PET nanocomposites were collected to analyze the dispersion of graphene nanoplatelets.
  • the Raman spectrums indicate that the nanoplatelets dispersed in to the PET matrix are multi layered.
  • Raman spectroscopy can also be used to determine the presence of ⁇ - ⁇ interactions between PET and graphene layers.
  • Fig. 64 shows the Raman bands (-1617 cm -1 ) corresponding to C— C stretching for PET and nanocomposites with increasing GNP content. A change in the band positions determined from peak fits can be observed in Fig. 65. This shift in the Raman band (-1617 cm "1 ) corresponding to C— C stretching in the phenyl ring of PET is an indication of the interaction with graphene.
  • the stress-strain curves indicate a more complex yielding behavior, as indicated in Fig. 71.
  • Platelet-platelet interaction is not likely at low fractions. Not only is the platelet volume fraction important, the platelet surface area at that volume fraction is important. At higher volume fractions a low surface area platelet is expected to have a similar benefit as a high surface area platelet at lower fractions. However, eventually, the platelets begin to interact across the matrix and that interaction will impact yielding behavior. Platelet-platelet bonding is much weaker than platelet-matrix bonds. In this case, we started to see more pronounced evidence of this interaction above 10% volume fraction platelets.

Abstract

La présente invention concerne une composition et un procédé pour obtenir du polyéthylène téréphtalate renforcé de graphène (PET). Des nanodisquettes de graphène (GNP) comprenant du graphène multicouche sont utilisées pour renforcer le PET, permettant ainsi d'améliorer les propriétés du PET pour diverses nouvelles applications. Des mélanges maîtres comprenant du polyéthylène téréphtalate présentant des nanodisquettes de graphène dispersées sont obtenus par mélange. Les mélanges maîtres sont utilisés pour former des nanocomposites PET-GNP selon des fractions pondérales comprises entre 0,5 % et 15 %. Dans certains modes de réalisation, le PET et les GNP sont soumis à un mélange par fusion par extrusion double vis. Dans certains modes de réalisation, un dispositif à ultrasons est couplé à une extrudeuse double vis de manière à faciliter le mélange par fusion. Dans certains modes de réalisation, les nanocomposites PET-GNP sont préparés au moyen d'un moulage par injection à grande vitesse. Les nanocomposites PET-GNP sont comparés suivant leurs propriétés mécaniques, thermiques et rhéologiques de manière à distinguer différents procédés de mélange.
