Polymer-dispersed liquid crystal elastomers as moldable shape-programmable material

Abstract

Development of Soft shape-memory materials is often limited to the synthesis of two-dimensional specimens and rely on bending mechanisms and scaffolding topology to perform three-dimensional morphing. Here, the authors demonstrate a shape-memory composite material made from main-chain liquid crystal elastomer microparticles dispersed in a silicone polymer matrix which enables molding into full-volume objects of any shape or size.
