Toward Programmed Complex Stress-Induced Mechanical Deformations of Liquid Crystal Elastomers

open access: yesCrystals, 2020
We prepare a liquid crystal elastomer (LCE) with a spatially patterned liquid crystal director field from an all-acrylate LCE. Mechanical deformations of this material lead to a complex and spatially varying deformation with localised body rotations ...
