Shape memory epoxy: Composition, structure, properties and shape memory performances
Abstract
Due to the intrinsic properties of polymers, medical applications have been the primary targets for the development of shape memory polymers (SMPs) exhibiting softness at body temperature, biocompatibility, high deformability, good shape recovery (Rr) and good shape fixity (Rf). However, there is an increasing need for developing smart materials that would meet the drastically different requirements imposed by applications where, instead, high strength well above room temperature, durability, stability, and high thermo-mechanical endurance are necessary. Here, we present results obtained on a series of shape memory (SM) epoxies that appear promising base materials for such applications. The influence of molecular and structural design on their physical and SM properties were studied. The impact of various SM programming conditions (i.e., deformation load, recovery heating rate, number of cycles, and isothermal holding times in the hot and cold deformed shapes) was also investigated. The instantaneous SM behavior was found similar for all the networks with Rf and Rr values nearing 100% above 6 to 7% strain. The SM performances strongly depended on the strain-dependent thermal expansion/contraction of the materials during thermo-mechanical cycling. Networks with lower crosslink density, higher chain flexibility and/or mobility showed reduced SM performances, further diminished by more stringent thermo-mechanical cycling conditions.

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.
