Abstract

The present work studies the synergistic effect of carbon nanofiber (CNF) and carbon nanopaper on the shape recovery of shape memory polymer (SMP) composite. The combination of CNF and carbon nanopaper was used to improve the thermal and electrical conductivities of the SMP composite. The carbon nanopaper was coated on the surface of the SMP composite in order to achieve the actuation by electrical resistive heating. CNFs were blended with the SMP resin to improve the thermal conductivity to facilitate the heat transfer from the nanopaper to the underlying SMP composite to accelerate the electroactive responses.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • The carbon nanopaper/(carbon nanofiber/shape memory polymer) structure significantly improved the electrical shape memory effect and the electrical response speed of the carbon nanopaper/shape memory polymer laminates.

    “The CNP/(CNF/SMP) structure significantly improved the electrical SME and the electrical response speed of the CNP/SMP laminates.”
  • The CNP/(CNF/SMP) structure significantly improved the electrical SME and the electrical response speed of the CNP/SMP laminates.

    “The CNP/(CNF/SMP) structure significantly improved the electrical SME and the electrical response speed of the CNP/SMP laminates.”
  • In carbon nanofiber/nanopaper epoxy SMP composites, shortest detected shape recoveries took 186 s and shape recoverabilities were reduced with increasing carbon nanofiber contents.

    “Nevertheless, the shortest detected shape recoveries took quite long (186 s) and shape recoverabilities were reduced with increasing carbon nanofiber contents”
  • Blending carbon nanofibers and coating carbon nanopaper onto epoxy-based SMP resin Veriflex E2 lowered electrical resistivity of composite 10^16 times compared to pure SMP resin.

    “Due to the synergistic effects of fibers and paper, heat transfer was facilitated and the electrical resistivity of the SMP composite was 10 16 times lower than for pure SMP resin.”

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.
