Flexible, shape-editable wood-based functional materials with acetal linkages

Abstract

A flexible, shape-editable transparent wood (ATW) composite containing acetal linkages were prepared through free radical polymerization and addition reaction between vinyl ether bonds and hydroxyl groups simultaneously. In this system, the anisotropic hierarchical structure of wood acted as reinforced skeleton, the flexible chain segment ensured flexibility at room temperature, and the dynamic acetal bonds were responsible for the shape memory and edition under relatively mild conditions, verifying the expanding applications of functionalized wood-based materials.
