Remote Controlled Multishape Polymer Nanocomposites with Selective Radiofrequency Actuations
Abstract
A multicomposite shape memory polymer (SMP) with remote and selective triggering of the recovery of multiple temporary shapes in radiofrequency fields is demonstrated. Each deformed region can be independently actuated at a specific frequency based on the filler type in the region. In addition, the nanocomposite SMP exhibits multiple temporary shapes and multiple possible shape recovery routes.

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.
