Polymer-dispersed liquid crystal elastomers [PDF]

Nature Communications, 2016
Liquid crystal elastomers are promising for building actuators due to excellent thermomechanical response, but it is challenging to prepare them at macroscale with arbitrary shape.

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 ...

Instabilities in liquid crystal elastomers [PDF]

MRS Bulletin, 2021
Stability is an important and fruitful avenue of research for liquid crystal elastomers. At constant temperature, upon stretching, the homogeneous state of a nematic body becomes unstable, and alternating shear stripes develop at very low stress ...

Soft Elasticity in Main Chain Liquid Crystal Elastomers

Crystals, 2013
Main chain liquid crystal elastomers exhibit several interesting phenomena, such as three different regimes of elastic response, unconventional stress-strain relationship in one of these regimes, and the shape memory effect.

Dynamic Self-Stiffening in Liquid Crystal Elastomers [PDF]

Nature Communications, 2013
Biological tissues have the remarkable ability to remodel and repair in response to disease, injury and mechanical stresses. Synthetic materials lack the complexity of biological tissues, and man-made materials that respond to external stresses through a

Biaxial liquid crystal elastomers: a lattice model

The European Physical Journal E, 2008
We present a simple coarse-grained lattice model for monodomain biaxial liquid-crystal elastomers and perform large-scale Monte Carlo simulations in the proposed model system.

Fracture of liquid crystal elastomers. [PDF]

Proc Natl Acad Sci U S A
Liquid crystal elastomers (LCEs) are anisotropic, viscoelastic materials integrating polymer networks and liquid crystals. While their mechanical responses have been extensively studied, their fracture behavior remains largely unexplored. Specifically, the effect of the deformation-director coupling on LCE fracture paths is unknown, and fracture ...
