The Shape Memory behavior of neat and cross-linked Poly (ethyleneterephthalate)

In recent years, the interest in improving shape memory behavior of polymers has increased. Also,fewer studies approached the use of poly (ethylene terephthalate) (PET). This work reports the shapememory behavior of neat and permanent cross-linked PET using Joncryl ADR (ADR) as an epoxycross-linker. The results showed that the recovery speed of the cross-linked sample was more thanthe neat one. Moreover, the shape recovery of the neat PET was ۸۰% while the shape recovery of thePET/ADR was ۹۳% which is due to the presence of cross-links. Cross-links afforded stronger elasticresilience for the recovery driving force.
