Biological liquid crystal elastomers [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002
Liquid crystal elastomers (LCEs) have recently been described as a new class of matter. Here we review the evidence for the novel conclusion that the fibrillar collagens and the dragline silks of orb web spiders belong to this remarkable class of materials. Unlike conventional rubbers, LCEs are ordered, rather than disordered, at rest.

Photothermal-Driven Liquid Crystal Elastomers: Materials, Alignment and Applications

Molecules, 2022
Liquid crystal elastomers (LCEs) are programmable deformable materials that can respond to physical fields such as light, heat, and electricity. Photothermal-driven LCE has the advantages of accuracy and remote control and avoids the requirement of high ...

Accurate and Anti‐Interference Control of Computer Vision‐Assisted Light‐Driven Liquid Crystal Elastomer Actuator

Advanced Intelligent Systems
Photoresponsive liquid crystal elastomer (LCE) plays an important role in soft robotics and other high‐tech fields. The deformation of smart materials directly affects the behavior of the actuator, which needs to be accurately controlled.

Preparation of Monodomain Liquid Crystal Elastomers and Liquid Crystal Elastomer Nanocomposites [PDF]

Journal of Visualized Experiments, 2016
LCEs are shape-responsive materials with fully reversible shape change and potential applications in medicine, tissue engineering, artificial muscles, and as soft robots. Here, we demonstrate the preparation of shape-responsive liquid crystal elastomers (LCEs) and LCE nanocomposites along with characterization of their shape-responsiveness, mechanical ...

Layered liquid crystal elastomer actuators [PDF]

Nature Communications, 2018
AbstractLiquid crystalline elastomers (LCEs) are soft, anisotropic materials that exhibit large shape transformations when subjected to various stimuli. Here we demonstrate a facile approach to enhance the out-of-plane work capacity of these materials by an order of magnitude, to nearly 20 J/kg.

Shape-programmable liquid crystal elastomer structures with arbitrary three-dimensional director fields and geometries

Nature Communications, 2021
Pre-patterning director fields into liquid crystal elastomers enables programmed morphing upon actuation. Guo et al. realize 3D skeletal assemblies with previously non-achievable director fields and morphing modes.

Four-Dimensional Printing of Temperature-Responsive Liquid Crystal Elastomers with Programmable Shape-Changing Behavior

Biomimetics, 2023
Liquid crystal elastomers (LCEs) are polymer networks that exhibit anisotropic liquid crystalline properties while maintaining the properties of elastomers, presenting reversible high-speed and large-scale actuation in response to external stimuli ...
