Strengthening Liquid Crystal Elastomer Muscles
Accounts of Chemical ResearchConspectusLiquid 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

Molecular Orientation in Liquid Crystal Elastomers
Macromolecules, 2005Free-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 ...

Biaxial liquid-crystal elastomers: A lattice model
The European Physical Journal E, 2008We 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. Orientational ordering--uniaxial or biaxial--reflects in sample deformations on cooling the system.

Polydomains in liquid‐crystal elastomers
Macromolecular Theory and Simulations, 1994AbstractIn liquid‐crystal elastomers, the simultaneous presence of rubber elasticity due to the crosslinked backbone chains and of optical birefringence due to the mesogens in the side chains lead to exceptional physical properties. An elastic deformation of the network influences the order of the mesogens and, therefore, the optical properties.

Photoresponsive Liquid Crystal Elastomers
2016In this chapter, one very interesting function of azo polymers is discussed, which is unique for the azobenzene-containing liquid crystal polymers with light cross-linking. These azo polymer networks, which are classified as azo liquid crystal elastomers, show many interesting properties and potential applications in actuators, shape memory, and others.

Review of Liquid Crystal Elastomers
2020Chapter 20 reviews liquid crystal elastomers (LCEs), first discussed by Finkelmann. These materials can be used as robotic actuators via inducing a nematic–isotropic phase transition in them upon a temperature increase, which causes them to shrink, as described in a thorough review on these intelligent multi-functional materials by Brand and Finkelmann.

Chirality in Liquid Crystal Elastomers
2006The coupling between the properties of conventional polymer networks and the properties of chiral liquid crystalline phases results in interesting, new opto- and electromechanical effects of the chiral liquid crystalline elastomers, as demonstrated by theoretical considerations and experiments.
