Crosslinked liquid crystalline polymers have demonstrated huge potential to implement soft responsive elements; however, the complexity and size of the actuators are limited by the current dominant thin-film geometry processing toolbox. Using 3D printing, stimuli-responsive liquid crystalline elastomeric structures are created here. The printing process prescribes a reversible shape-morphing behavior, offering a new paradigm for active polymer system preparation. The additive character of this technology also leads to unprecedented geometries, complex functions, and sizes beyond those of typical thin-films. The fundamental concepts and devices presented therefore overcome the current limitations of actuation energy available from thin-films, thereby narrowing the gap between materials and practical applications. info:eu-repo/grantAgreement/ES/MINECO/SAF2014-54763-C2-2-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.078 2018 POLYMER SCIENCE 9 / 86 = 0.105 2018 Q1 T1 1.31 2018 Materials Chemistry 2018 Q1 Polymers and Plastics 2018 Q1 Organic Chemistry 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Liu, D.
