Shape memory polymers (SMPs) are materials that can undergo programmable shape change in response to a specific stimulus. The ability to undergo this reliable, three-dimensional shape change makes SMPs promising smart materials for applications like biomedical stents and sutures.

Melting of the crystalline regions via heat causes a drop in the modulus of the material facilitating wetting of the substrate as well as enhancing the surface contact area with the substrate, which result in The shape-memory effect at the microlevel was quantified by the recovery ratio of cuboids (R r,micro), while at the nanolevel, the recovery ratio of the nanoroughness (R r,nano) was measured. The values of R r,micro could be tailored in a range from 42 ± 1% to 102 ± 1% and R r,nano from 89 ± 6% to 136 ± 21% depending on the applied compression ratio and the amount of vinyl acetate content 2019-12-30 · 4D printing is proposed based on the additive manufacturing of stimuli-responsive materials and structures, which can realize shape changing upon external stimuli.

This research was supported by the Chen Neuroscience Institute and the U.S. Department of Defense. 2016-08-08 · Two key attributes of SMPs are their ability to fix a temporary programmed shape (fixity) and to subsequently recover the original shape upon activation by a stimulus (recovery). Multistimuli‐responsive shape‐memory polymers are highly desirable in various applications, and numerous modes have been developed in recent years. However, most of them need to reprogram before they are ready to respond to another stimulus while one is triggered. Shape memory polymers (SMPs) are materials that can undergo programmable shape change in response to a specific stimulus.
