Abstract

Shape-memory polymers can revert to their original shape when they are reheated. The stress generated by shape recovery is a growing function of the energy absorbed during deformation at a high temperature; thus, high energy to failure is a necessary condition for strong shape-memory materials. We report on the properties of composite nanotube fibers that exhibit this particular feature. We observed that these composites can generate a stress upon shape recovery up to two orders of magnitude greater than that generated by conventional polymers. In addition, the nanoparticles induce a broadening of the glass transition and a temperature memory with a peak of recovery stress at the temperature of their initial deformation.

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 temperature-memory effect approach has been largely employed to achieve multiple-way SMPs with a broad glass transition or a broad melting transition as the switching transition.

    “Such an approach has been largely employed to achieve multiple-way SMPs with a broad glass transition [82-92] and a broad melting transition [93-95] as the switching transition.”
  • Miaudet et al. achieved the highest recovery stress of shape memory polymer composites; the maximal stress generated by a carbon nanotube/polyvinyl alcohol fiber reached 150 MPa, two orders of magnitude higher than that of neat shape memory polymers.

    “Among all the outstanding achievements, Miaudet et al. [290] achieved the highest recovery stress of SMPCs.The maximal stress generated by a CNT/polyvinyl alcohol fiber reached 150 MPa which is two orders of magnitude higher than that of neat SMPs.”

  • In PVA/CNTs fibrous membranes, nanotubes induced a broadening of the Tg and a temperature memory with a peak of recovery stress at the temperature of their initial deformation.

    “For example in the case of fibrous membranes from poly(vinyl alcohol) (PVA)/CNTs the nanotubes induced a broadening of the Tg and a temperature memory with a peak of recovery stress at the temperature of their initial deformation.”
  • The generated stress upon shape recovery was up to two orders of magnitude greater than that characteristic for conventional polymers.

    “Interestingly, the generated stress upon shape recovery was up to two orders of magnitude greater than that one characteristic for the conventional polymers [114].”

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.
