Synergistic effects in mechanical properties of PLA/PCL blends with optimized composition, processing, and morphology

Original language description

Poly(lactic acid) (PLA) is a promising material for biomedical applications due to its biodegradability and high stiffness, but suffers from low toughness. We report that blending of PLA with another biodegradable polymer, poly(?-caprolactone) (PCL), canincrease the impact strength above the values of the individual components, while the other important macro- and micromechanical properties remain at well-acceptable level (above the theoretical predictions based on equivalent box model). Although someprevious studies indicated incompatibility of PLA and PCL polymers, we demonstrate that the melt-mixing of the polymers with optimized viscosities (PLA/PCL viscosity ratio similar to 1), the optimized composition (PLA/PCL = 80/20 by weight), and the optimal processing (compression molding with fast cooling) leads to optimal morphology (similar to 0.6 ?m particles of PCL in PLA matrix) and synergistic effect in the mechanical performance of the systems.
