Abstract

ABSTRACT Polyesters based on polyols and sebacic acid, known as poly(polyol sebacate)s (PPS), are attracting considerable attention, as their properties are potentially useful in the context of soft‐tissue engineering applications. To overcome the drawback that PPSs generally display rather low strength and stiffness, we have pursued the preparation of nanocomposites based poly(mannitol sebacate) (PMS), a prominent example of this materials family, with cellulose nanocrystals (CNCs). Nanocomposites were achieved in a two‐step process. A soluble, low‐molecular‐weight PMS pre‐polymer was formed via the polycondensation reaction between sebacic acid and D‐mannitol. Nanocomposites with different CNC content were prepared by solution‐casting and curing under vacuum using two different profiles designed to prepare materials with low and high degree of crosslinking. The as‐prepared nanocomposites have higher stiffness and toughness than the neat PMS matrix while maintaining a high elongation at break. A highly crosslinked nanocomposite with a CNC content of 5 wt % displays a sixfold increase in Young's modulus and a fivefold improvement in toughness. Nanocomposites also exhibit a shape memory effect with a switch temperature in the range of 15 to 45 °C; in particular the materials with a thermal transition in the upper part of this range are potentially useful for biomedical applications. © 2014 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?

  • The SME of PMS containing nanocomposites was in the range of physiological temperatures.

    “The SME of the PMS containing nanocomposites was in the range of physiological temperatures”
  • The enhancement was related to hydroxyl groups on the CNCs surface that efficiently interacted with the polymer matrix.

    “This effect was related to the presence of the hydroxyl groups in the CNCs surface that efficiently interacted with the polymer matrix.”
  • Mechanical properties of PMS network were enhanced by incorporation of 5 wt% CNCs, with six-fold increase in Young's modulus and five-fold improvement in toughness.

    “The mechanical properties of poly(mannitol sebacate) (PMS) network were also enhanced by the incorporation of 5 wt% CNCs (six-fold increase in Young's modulus and five-fold improvement in toughness) [188].”

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.
