Polycaprolactone composite films infused with hyperbranched polyester/reduced graphene oxide: Influence on biodegradability, gas/water transport and antimicrobial properties for sustainable packaging
Open accessAbstract
as models for Gram-positive and Gram-negative bacteria, respectively. The biodegradability test performed on the prepared film PCL, and those containing 1% of the filler, PCL/RGO, and PCL/mRG, emphasized that the film degradation became pronounced after three months for all samples.

High crystallinity and hydrophobicity of PCL slow its degradation rate.
“High crystallinity and hydrophobicity of PCL also slow the degradation rate [6,49]”
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 [6]
The Introduction describes PCL as semi-crystalline and refers to its low degradation rate. The Thermal properties section reports about 71% crystallinity for neat PCL, and Surface wettability describes its surface as less hydrophilic. Neither section, nor the Ability for biodegradation section, says that crystallinity or hydrophobicity causes the slow degradation. (LLM, conf=0.82)

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.
