Abstract

Abstract Polylactide (PLA)/poly(butylenes adipate‐co‐terephthalate) (PBAT) blends with various composition ratios were prepared via melt compounding using a twin‐screw extruder. The dynamic rheological behavior and morphology of the blends were studied using a parallel‐plate rheometer and a scanning electron microscope (SEM), respectively. The results showed that the shear‐thinning tendency of blends became stronger with increasing PBAT content. Moreover, at low frequencies, the complex viscosity, storage modulus and loss modulus for blends with 20 wt% PBAT content were higher than that of other samples when PBAT content was less than 50 wt%. Based on SEM images, three distinct morphologies—spherical droplet, elongated fibrous structure, and co‐continuous structure—were observed as the content of PBAT increased from 5 to 50 wt%. When the PBAT content reached 70 wt% and above, the morphology became droplets again, with PLA droplets dispersing within the PBAT matrix. In addition, the PLA droplets in the PBAT/PLA (80/20 w/w) blend were smaller and more regular than the PBAT droplets in the PLA/PBAT (80/20 w/w) blend, despite the same composition ratio. © 2011 Wiley Periodicals, Inc.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • At lower frequencies, the complex viscosity of the samples increases with increasing PLA content (from 10 to 100 wt.%).

    “At lower frequencies, the complex viscosity of the samples increases with increasing PLA content (from 10 to 100 wt.%), which is contradictory to the result of Li et al. at 190 °C [26].”

    From Uncompatibilized PBAT/PLA Blends: Manufacturability, Miscibility and Properties (2020) · cites this paper as [26]

  • The left side of the S-shape shows relaxation of one blend component (polymer matrix) and the right side is attributed to another blend component (droplet relaxation).

    “The left side shows the relaxation of one blend component (polymer matrix) and the right side is attributed to another blend component (droplet relaxation) [26,27,28].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
