Abstract

Carbon nanotubes are light, stiff and electroactive materials particularly promising in the field of actuating materials. Indeed, carbon nanotubes can expand and contract upon charge injection and be used for the development of electromechanical actuators. Carbon nanotubes can also be included in polymers to improve their properties and bring specific functionalities. When added to shape memory polymers, carbon nanotubes yield an improved stiffness and the possibility to heat the material through Joule’s heating. Nevertheless, spatial ordering of the nanotubes is a critical issue in all these classes of actively moving materials. It is shown in this article that assembling nanotubes under the form of pure or composite fibers is an effective approach to orient carbon nanotubes on a large scale along a well defined direction. Nanotube alignment achieved via fiber drawing allows the optimization of properties of shape memory polymer fibers and electrochemical actuators. In particular, the mechanical response of pure nanotube fibers to electrical stimulations is investigated in liquid electrolytes. It is observed that the fibers can generate a stress one order of magnitude greater than that achieved with unaligned assemblies of nanotubes. We also present the properties of shape memory polymer fibers loaded with carbon nanotubes. These fibers generate a very large stress when they recover their shape after they have been stretched and cooled under tensile load. Composite nanotube polymer fibers also exhibit a temperature memory behavior, which is still raising fundamental questions regarding its microscopic origin.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Functionalized MWCNTs lead to the best reinforcing effect.

    “The functionalized MWCNTs lead to the best reinforcing effect.”
  • Porous fibers remaining after thermal degradation of PVA/SWCNT composites comprised entangled CNTs held by van der Waals interactions and had better mechanical properties than random assemblies of nanotubes in bucky paper.

    “The remaining porous fibers were comprised of entangled CNTs, held together by van der Waals interactions, and had much better mechanical properties than random assemblies of nanotubes in bucky paper.”
  • PVA/SWCNT SMP composites manufactured by Viry et al. had maximum recovery stresses close to 150 MPa when deformed near Tg = 80 °C of neat PVA, fixed by cooling under fixed strain and reheated.

    “The manufactured SMP composites revealed maximum recovery stresses close to 150 MPa when deformed at temperatures that were in the vicinity of T g = 80 °C of neat PVA, adjacently fixed through cooling under fixed strain and reheated.”

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.
