  • PCL is semi-crystalline with a reported degree of crystallinity of ca. 40%, a melting temperature of 58-64 °C, and a glass transition temperature of −65 to −60 °C.

    “PCL is semi-crystalline, with spherulites consisting of lamellae oriented in parallel and separated by amorphous regions with a reported degree of crystallinity of ca. 40%, a melting temperature in the range of 58–64 °C, and a glass transition temperature in the range of −65 to −60 °C (see Table 1) [35,46,47]”

    From Nanocellulose-Reinforced Poly(Lactic Acid) and Poly(ε-caprolactone) Bio-Nanocomposites: A Review and Future Outlook for Poly(Lactic Acid)/Poly(ε-caprolactone) Blend Systems (2025) · cites this paper as [35]

    Section 2 (page unavailable) describes PCL as semi-crystalline, with a glass transition temperature of −60 °C and a melting range of 59–64 °C. The cited copy does not give approximately 40% crystallinity or the claimed lower bounds of −65 °C and 58 °C. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The required time for complete resorption of PDLLA is approximately 1-2 years, whilst PCL requires 2-4 years.

    “It was reported that the required time for complete resorption (degradation time) of poly(D,L-lactide) (PDLLA) is approximately 1-2 years, whilst poly(ɛ-caprolactone) (PCL) requires 2-4 years [1,67,68].”

    From <i>In vitro</i> degradation and mechanical properties of PLA-PCL copolymer unit cell scaffolds generated by two-photon polymerization (2016) · cites this paper as [1]

    Section 3 (Biodegradation; page not provided) states that PCL homopolymer takes two to four years to degrade completely, depending on its starting molecular weight. The copy does not give a one-to-two-year complete-resorption time for PDLLA; Section 1 says only that PCL degrades more slowly than poly(D,L-lactide). (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • PLA tensile strengths are in the range of 50-70 MPa.

    “Woodruff et al. [35] reported tensile strengths in the range of 50–70 MPa.”

    From Nanocellulose-Reinforced Poly(Lactic Acid) and Poly(ε-caprolactone) Bio-Nanocomposites: A Review and Future Outlook for Poly(Lactic Acid)/Poly(ε-caprolactone) Blend Systems (2025) · cites this paper as [35]

    Section 8.6 discusses the mechanical behavior of PLA-containing scaffolds, but does not give a tensile-strength range for PLA. Searches for “50–70 MPa” and PLA tensile strength found no passage in our copy reporting the claimed range; no page number was available for the passages reviewed. (LLM, conf=0.73)

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.
