Dynamic Liquid Crystal Elastomers for Body Heat- and Sunlight-Driven Self-Sustaining Motion via Material-Structure Synergy.

Angewandte Chemie
Self-sustained actuators powered by natural, low-energy sources based on liquid crystal elastomers (LCEs) are attractive as they offer high safety, abundant energy availability, and practicality in applications.

Body Temperature Actuated Liquid Crystal Elastomers from Hyper Tensile Preprogramming

Advanced Functional Materials
Creating thermally actuated liquid crystal elastomers (LCE) traditionally requires mechanical pre‐straining to cure in an aligned state, with higher pre‐strains generally improving alignment and actuation. However, excessive pre‐strains risk damaging the

Liquid Crystal Elastomers

2003
Abstract Liquid crystals are fluids with a directionality defined. Polymers are long molecules with a shape that can be changed. As a network, polymers form rubber - a soft solid that is locally liquid-like and capable of huge extension.

Transitions and instabilities in liquid crystal elastomers

Physical Review E, 1993
Solid nematic liquids, formed by cross-linking polymer liquid crystals into elastomers, are shown to display novel and complex elasticity. The internal (nematic) direction suffers a barrier to its rotation and this couples to standard elasticity. By considering imposed strains we illuminate this elasticity and also demonstrate an entirely new nematic ...

Stimuli‐Responsive Liquid Crystal Elastomers: From Materials to Applications

Advanced Functional Materials
Liquid crystal elastomers (LCEs) are well‐known for their significant, reversible, and anisotropic shape changes when exposed to different external stimuli due to their crosslinked polymer networks that merge the elastic properties of rubbers with the ...

Molecular Orientation in Liquid Crystal Elastomers

Macromolecules, 2005
Free-standing and confined anisotropic liquid crystal elastomer films of various thicknesses have been prepared using mesogens with laterally affixed polymerizable side chains. Textures have been studied by microscopy, whereas molecular orienation of the mesogen groups has been investigated by polarized FTIR and Raman spectroscopies considering an ...

Active Terahertz Nonlocal Metasurfaces With Liquid Crystal Elastomers

Laser & Photonics Reviews
Achieving active tunability in metasurfaces remains a critical challenge, with conventional local metasurfaces limited by dispersive wavefront deflection and broad resonances that lack spectral selectivity. In contrast, nonlocal metasurfaces exhibit high

Cluster‐Triggered Self‐Luminescence, Rapid Self‐Healing, and Adaptive Reprogramming Liquid Crystal Elastomers Enabled by Dynamic Imine Bond

Advances in Materials
The integration of advanced functions and diverse practical applications calls for multifunctional liquid crystal elastomers (LCEs); however, the structure‐intrinsic luminescence and excellent mechanical properties of LCEs have not yet been explored.

Strengthening Liquid Crystal Elastomer Muscles

Accounts of Chemical Research
ConspectusLiquid crystal elastomer fibers (LCEFs) are reversible artificial muscles capable of stimuli-responsive functions, making them promising competitors for ideal soft actuators. These remarkable actuation properties depend strongly on their mechanical properties, such as elastic modulus and breaking stress. It is necessary to strengthen the LCEF
