Triple‐Shape Polymeric Composites (TSPCs)

Luo, Xiaofan, Mather, Patrick T.·2010·Advanced Functional Materials

Abstract

In this paper, the fabrication and characterization of triple‐shape polymeric composites (TSPCs) that, unlike traditional shape memory polymers (SMPs), are capable of fixing two temporary shapes and recovering sequentially from the first temporary shape (shape 1) to the second temporary shape (shape 2), and eventually to the permanent shape (shape 3) upon heating, are reported. This is technically achieved by incorporating non‐woven thermoplastic fibers (average diameter ∼760 nm) of a low‐ T m semicrystalline polymer into a T g ‐based SMP matrix. The resulting composites display two well‐separated transitions, one from the glass transition of the matrix and the other from the melting of the fibers, which are subsequently used for the fixing/recovery of two temporary shapes. Three thermomechanical programming processes with different shape fixing protocols are proposed and explored. The intrinsic versatility of this composite approach enables an unprecedented large degree of design flexibility for functional triple‐shape polymers and systems.

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

  • Alternative methods for creating multiple, well-separated switching transitions in one system consist of laminating two SMPs with well-separated transition temperatures or developing hybrid SMPs with multiple thermal transitions.

    “Alternative methods for creating multiple, well-separated switching transitions in one system consist of laminating two SMPs which have well-separated transition temperatures [76,77] or of developing hybrid SMPs with multiple thermal transitions [78-81].”
  • Electrospun polycaprolactone nanofiber mat with a low melting transition immersed into a glass transition type shape memory epoxy matrix has two separated thermal transitions: one from the glass transition of the epoxy and the other from the melting of the polycaprolactone fibers.

    “Fig. 10(I) shows the elastic modulus profiles which indicate the two separated thermal transitions of the composites.One is from the glass transition of the epoxy and the other from the melting of the polycaprolactone fibers.”
  • The composite of electrospun PCL nanofibers in shape memory epoxy shows triple SME.

    “Fig. 10(II) shows the triple SME of the composite.”
  • Luo and co-workers embedded non-woven PCL fibers into a Tg-depending matrix (epoxy-based copolymer thermoset with Tg from 20 °C to 45 °C) offering well-controlled systems with large degree of flexibility.

    “An year later, Luo and co-workers embedded non-woven PCL fibers into a Tg-depending matrix (epoxy-based copolymer thermoset with a Tg from 20 ° C to 45 ° C) offering well-controlled systems with large degree of flexibility [75].”

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.
