Triple-shape memory effect of covalently crosslinked polyalkenamer based semicrystalline polymer blends
Abstract
Triple-shape memory polymers are developed by blending and crosslinking two semicrystalline polymers (poly(cyclooctene), PCO, and polyethylene, PE) towards creating two pronounced segregated crystalline domains within a covalently crosslinked network. The key thermo-mechanical properties of a series of a polyalkenamer and a polyolefin based polymer blends are characterised using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). Furthermore, the versatile multi-shape memory functionality is demonstrated, and main shape memory response is evaluated by performing consecutive thermo-mechanical bending experiments based on a two-step programming process and subsequent progressive thermal recovery. The proposed approach, thanks to the excellent achieved shape memory properties, as well as the possibility of tailoring the thermo-mechanical response, is presented as a versatile method to increase the potential applications of these thermo-active materials by designing optimal compositions.

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.
