The starch nanocrystal filled biodegradable poly (ε-caprolactone) composite membrane with highly improved properties

Abstract

The platelet-like starch nanocrystal (SNC) particles were used to prepare composite membrane with biodegradable poly(ε-caprolactone) (PCL) for the potential packaging membrane application. The presence of SNC particles improves gas barrier properties, tearing strength, as well as the creep resistance of the PCL membrane evidently at the lower loading levels. This improvement effect can be further enhanced by the surface acetylation of SNC. The presence of acetylated SNC particles (1wt%) can reduce the oxygen transmission rate by about 70% and increase the tearing strength by about 68%, which is due to the improved phase adhesion. The strain failure stage of the membrane is also highly delayed in the presence of acetylated SNC, from hour-time scale to day-time one. Therefore, the biodegradable SNC is a promising candidate to be used as the filler to improve the key properties of biodegradable PCL membrane, but the chemically modified SNC is the better option.

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.
