AI Article Synopsis

  • The paper discusses the creation and characteristics of biodegradable thermoplastic blends with triple-shape memory capabilities, made by blending poly(l-lactide--glycolide) with bioresorbable aliphatic oligoesters.
  • The inclusion of oligoesters lowers the glass transition temperature and enhances both flexibility and shape memory traits in the blends.
  • Blends with under 20 wt% of oligo (butylene succinate--butylene citrate) are highlighted as especially promising for biomedical uses, such as in bioresorbable implants, due to their good mechanical properties and uniform physical characteristics.

Article Abstract

The paper presents the formation and properties of biodegradable thermoplastic blends with triple-shape memory behavior, which were obtained by the blending and extrusion of poly(l-lactide--glycolide) and bioresorbable aliphatic oligoesters with side hydroxyl groups: oligo (butylene succinate--butylene citrate) and oligo(butylene citrate). Addition of the oligoesters to poly (l-lactide--glycolide) reduces the glass transition temperature (T) and also increases the flexibility and shape memory behavior of the final blends. Among the tested blends, materials containing less than 20 wt % of oligo (butylene succinate--butylene citrate) seem especially promising for biomedical applications as materials for manufacturing bioresorbable implants with high flexibility and relatively good mechanical properties. These blends show compatibility, exhibiting one glass transition temperature and macroscopically uniform physical properties.
