Magnetoactive liquid crystal elastomer nanocomposites
Abstract
We present liquid crystal elastomer (LCE) nanocomposites containing superparamagnetic nanoparticles that perform local heat dissipation upon irradiation with electromagnetic fields. A fast local temperature rise is observed that leads to a distinct contraction at the nematic–isotropic transition temperature of the elastomer. The materials exhibit contractions up to 27% of the original length with short response times. We found the heat production rate and the heat transfer coefficient the parameters that determine the maximum contraction rate.

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.
