Overview

Investigates how D-lactide content and PBAT blending affect the physical aging and ductility of PLA, suggesting new methods for improving its properties.

Key Points

  • This research aims to understand how D-lactide content, high-temperature drawing, and PBAT blending affect the physical aging kinetics and ductility of PLA.
  • Investigated the influence of D-lactide content and PBAT blending on PLA's properties.
  • Conducted morphology and mechanical property analysis through ball-burst testing and SEM.
  • Assessed the impact of high-temperature drawing on the physical aging of PLA.
  • PBAT blending enhanced PLA's elongation at break and reduced physical aging rates.
  • Morphological analysis showed significant improvement in ductility due to PBAT inclusion.
  • High-temperature drawing was found to alter the phase structure, positively influencing mechanical properties.
