Abstract

This paper discusses the actuation durability of a conducting shape memory polyurethane (CSMPU) actuator. Introduced in 2004, the CSMPU actuator was manufactured by an in situ polymerization method for shape memory polyurethane with multi-walled carbon nanotubes. In order to apply the CSMPU to smart actuators and determine detailed design concepts, the durability data should be measured. Hence, the experiments in this research were designed to obtain durability data, and the maximum number of actuation cycles versus the initial elongation ratio and the actuation temperature were measured for the purpose of assessing durability. The broken surfaces of the specimens were investigated.

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?

  • For PCL-based SMPU containing MWCNTs, at 60% strain and 30 °C, a maximum of 420 cycles could be run.

    “For strains of 60%, a maximum of 420 cycles could be run at 30 °C, higher strains of 100% allowed 150 cycles to be run, whereas 120 cycles could be run at 60% strain and 40 °C.”

  • Higher actuation temperatures induce property degradation in PCL-based SMPU containing MWCNTs as a result of rapid movements of molecular chains.

    “The authors concluded that higher actuation temperatures induce property degradation as a result of the rapid movements of molecular chains.”

  • Specimen cycle life of PCL-based SMPU containing MWCNTs is dependent on deformation conditions (maximum strain and temperature).

    “They found that specimen cycle life was dependent on the deformation conditions (maximum strain and temperature).”

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.
