Abstract

A new type of shape memory polymer (SMP) employing vinyl-capped Fe3O4 nanoparticles as netpoints that determine the permanent shape for remote activation has been presented. The new design effectively prevents the nanoparticles from moving and re-aggregating in a polymer matrix and guarantees the stability of the SMP networks when a high temperature and external stress are applied. Therefore, durable shape memory performance is obtained during the programmed deformation-recovery processes. Meanwhile, a homogeneous distribution of vinyl-capped Fe3O4 nanoparticles achieves uniform heat generation and heat transfer in the alternating magnetic field. Consequently, the novel remote-activated SMP also exhibits a fast magnetic responsiveness compared to the SMPs physically dispersed with Fe3O4 nanoparticles.

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.
