Jan 1, 2014 · In this study, blends of biodegradable Poly (lactic acid) (PLA) and Polycaprolactone (PCL), were prepared using Hakee Rheomix and characterized for rheological, thermal, mechanical and viscoelastic properties. Morphology of tensile fractured surfaces was examined through scanning electron microscopy (SEM).

Sep 22, 2023 · In this work, the effectiveness of seven commercial compatibilizers is tested in polylactide (PLA)/poly (ε-caprolactone) (PCL) blends with different compositions to obtain a high-impact PLA. None of the compatibilizers is effective for 90/10 and 80/20 PLA/PCL compositions, as no improvement of the impact strength is observed.

Apr 9, 2021 · Blending PLA with polycaprolactone (PCL) helps improve the disadvantages of pure PLA. In this study, different molecular weights of PCL were used and blended with PLA in different proportions to form a composite film by melt blending.

Over the past years, poly (lactic acid) or polylactide (PLA) is commonly researched as a possible replacement for traditional fossil-based polymers because of its compostability, biocompatibility, and high mechanical properties. PLA has a variety of …

May 1, 2005 · A series of poly(ε-caprolactone)/poly(L-lactic acid) (PCL/PLA) biodegradable poly(ester-urethane)s, was synthesized and characterized. The first step of the synthesis consisted of the ring opening polymerization of L -lactide, initiated by the hydroxyl terminal groups of the PCL chain, followed by the chain extension of these PLA-PCL-PLA ...

Aug 1, 2019 · Available literature data suggest that the optimal composition for PLA/PCL blends is around 80/20 (w/w). The PLA/PCL (80/20) blends keep high stiffness of PLA matrix and the concentration of...
