Types of Step-Growth Polymers: Polyesters

2.2K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...

Summary

Grape stalk (GS) particles enhance biocomposite films made from poly (butylene succinate) (PBS) and poly(3-hydroxybutyrate)-co-hydroxyvalerate (PHBV). These active food packaging materials show improved antioxidant and UV-blocking properties, preserving sunflower oil.

Area of Science:

  • Materials Science
  • Polymer Science
  • Food Science

Background:

  • Grape stalk (GS) is a winemaking waste rich in antioxidant compounds.
  • Valorization of GS can lead to active food packaging materials.
  • Biocomposite films offer potential for sustainable packaging solutions.

Purpose of the Study:

  • To investigate the valorization of grape stalk (GS) waste into active food packaging materials.
  • To characterize biocomposite films made from poly (butylene succinate) (PBS) and poly(3-hydroxybutyrate)-co-hydroxyvalerate (PHBV) incorporating GS particles.
  • To evaluate the impact of GS incorporation on the physical, mechanical, barrier, and antioxidant properties of the films.

Main Methods:

  • Biocomposite films were prepared using melt blending of PBS and PHBV with 10% GS particles.
  • GS particles were subjected to subcritical water extraction at 170 °C and 180 °C.
  • Films were characterized for mechanical properties, crystallinity, thermal stability, oxygen barrier, and UV blocking.
  • The efficacy of the films in preserving sunflower oil against oxidation was assessed.

Main Results:

  • GS particles improved fiber integration in PHBV compared to PBS.
  • Incorporation of GS enhanced the stiffness of PBS films but reduced their break resistance and extensibility.
  • GS reduced the crystallinity and thermal stability of PHBV films, decreasing their rigidity.
  • All composite films exhibited improved oxygen barrier capacity (20-35%) and UV light blocking.
  • The active packaging films effectively preserved sunflower oil, with antioxidant compound migration observed in PHBV composites.

Conclusions:

  • Grape stalk particles can be effectively incorporated into PBS and PHBV biocomposites for active food packaging.
  • The composites demonstrate enhanced barrier properties and antioxidant activity, improving food preservation.
  • GS incorporation modifies the mechanical and thermal properties of the polymer matrices, with varying effects on PBS and PHBV.
