The role of the molecular weight in crystallization and melt memory poly(ε-caprolactone) (PCL) was investigated. To this end, 10 PCL samples synthetic commercial origin different chain ends, covering a number-average (Mn) range between 0.48 70.5 kg/mol, were analyzed. Polarized light optical microscopy, differential scanning calorimetry, small-angle X-ray scattering (SAXS) employed for in-depth characterization. thermal transitions, morphology, kinetics, structural parameters, effects...
Abstract 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 effective for 90/10 and 80/20 PLA/PCL compositions, as no improvement impact strength observed. For 70/30 composition, having glycidyl methacrylate (GMA) acrylate groups their structure are proved most effective, morphological change towards co‐continuity induced by them leads significant...
In this work, the toughening of a 70/30 polylactide (PLA)/poly(ε-caprolactone) (PCL) blend was achieved by addition nucleating agents (NAs) and tailoring processing conditions. To end, different NAs (TMC200, TMC300, TMC306, TMC328) were used to promote crystallization PLA. For comparison reasons, effect on PCL phase also analyzed. From polarized light optical microscope (PLOM) observations kinetics studies (performed differential scanning calorimetry), it concluded that TMC200 TMC328 most...
Polymer nanocomposites with superior multi-functional properties can be fabricated by tuning their morphology. In this work, a supertough and semiconductive polylactide (PLA)-based polymer blend nanocomposite (PBNANO) was produced for the first time via melt blending core-shell rubber (CSR) carbon nanotubes (CNT). Reference binary blends (PLA/CSR PLA/CNT) revealed that, when added separately, 20 wt% of CSR 0.25 CNT were suitable quantities to achieve PLA-based material, respectively. Based...
