| Outline of Final Research Achievements |
In this study, the bio-based shape memory materials were synthesized from epoxidized plant oil. The crosslinked plant oil-based materials were prepared from epoxidized soybean oil (ESO) by an acid-catalyzed curing in the presence of poly(vinyl chloride) (PVC). During the reaction, PVC scarcely reacted with ESO to form semi-interpenetrating network structure. The incorporation of the PVC components improved maximum stress and strain at break of the ESO-based network polymers. Furthermore, the polyESO/PVCs exhibited excellent shape memory properties, and the strain fixity and the recovery rate depended on the feed ratio of ESO and PVC. The shape memory-recovery behaviors were repeatedly practicable. The resulting materials are expected to contribute to the development of biodegradable intelligent materials.
