Abstract

In this work, a novel type of shape memory polymer nanocomposite was fabricated using chemically cross-linked poly(ε-caprolactone) with allyl alcohol as the matrix and Fe3O4 nanoparticles decorated conductive multiwalled carbon nanotubes (Fe3O4@M) as a magnetism and electricity responsive source. The nanocomposite exhibited excellent shape memory performance with a multistage stimulus recovery from a temporary shape to a permanent shape, triggered by an alternating magnetic field, an electric field and hot water, respectively. Uniquely, the nanocomposite also displayed significant two-way reversible shape memory behavior under constant load conditions, which was not demonstrated previously. An alamar blue assay was also used to prove that the material possessed good biocompatibility. The results showed that the material could have good potential application in sensors, functional tissue engineering constructs and artificial muscles.

  • The advantage was that the magnetic Fe3O4 layer covered the outside of the MWCNTs and contributed to the magnetic properties while the outside of the WMCNTs (without NPs loading) were responsible for the electric properties of the material.

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.
