Carbon nanotube chains in a shape memory polymer/carbon black composite: To significantly reduce the electrical resistivity
Abstract
Instead of individually aligned along the external electric field, the carbon nanotubes (CNTs) were electrically induced into aligned chains in a shape memory polymer (SMP)/carbon black (CB) composite, which would serve as long-distance conductive channels to bridge the CB aggregations. Compared with SMP composites with randomly filled CNTs, the electrical resistivity in those with chained CNTs was reduced for more than 100 times. The fabricated conductive SMP composites could be actuated by a low electrical power.

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.
