New Scalable Approach toward Shape Memory Polymer Composites via “Spring-Buckle” Microstructure Design
Abstract
Shape memory polymers (SMPs) have attracted tremendous research interest since their discovery. However, most advances in research of SMPs are based on molecular designs, i.e., "bottom-up" strategies. Due to the viscoelasticity of polymers, slow and incomplete shape variations are inevitable for most existing SMPs. Here, we propose a simple and scalable approach to design and fabricate SMP composites (SMPCs) based on a "spring-buckle" microstructure design. Specifically, a highly elastic "spring" is employed as a basic skeleton for the SMPCs, onto which self-adhesive and stimuli-responsive "buckles" are installed as reversible switch units. The resultant SMPCs with such "spring-buckle" microstructure enable quick programming at ambient temperature and ultrafast (2-3 s) and nearly complete (∼100%) shape recovery triggered by organic solvents, benefiting from a unique capillary effect. This structural approach provides a novel design philosophy for shape memory materials and opens up new opportunities for their applications in sensor, actuator, aerospace, and other applications.

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.
