Ferronematic Liquid Crystal Polymers and Elastomers
MATERIAIS 2022, 2022 Liquid crystal polymers, through covalent bonding, combine the spontaneous long range orientational order of the liquid crystal state with the entropically driven random coil configurations of the skeletal polymer chains in a single material [1]. [...]

Internal constraints and arrested relaxation in main-chain nematic elastomers
Nature Communications, 2021 Nematic liquid crystal elastomers (N-LCE) have a slow relaxation, which can prevent their shape recovery. Here, the authors examine mechanical hysteresis in a series of main-chain N-LCE to understand how the inherent nematic order retards and arrests the

Instabilities in liquid crystal elastomers [PDF]
MRS Bulletin, 2021 AbstractStability 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.

Morphing of liquid crystal surfaces by emergent collectivity
Nature Communications, 2019 Liquid crystal networks can morph their shape in response to electrical stimulus. Here the authors provide a detailed description of their deformation mechanism and introduce a method to observe the dynamic surface of liquid crystal elastomers.

Electroresponsive Ionic Liquid Crystal Elastomers
Macromolecular Rapid Communications, 2019 AbstractThis paper describes the preparation, physical properties, and electric bending actuation of a new class of active materials—ionic liquid crystal elastomers (iLCEs). It is demonstrated that iLCEs can be actuated by low‐frequency AC or DC voltages of less than 1 V.

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.

Electrospun Composite Liquid Crystal Elastomer Fibers [PDF]
Materials, 2018 We present a robust method to prepare thin oriented nematic liquid crystalline elastomer-polymer (LCE-polymer) core-sheath fibers. An electrospinning setup is utilized to spin a single solution of photo-crosslinkable low molecular weight reactive mesogens and a support polymer to form the coaxial LCE-polymer fibers, where the support polymer forms the ...

Liquid Crystal Elastomer Waveguide Actuators
Advanced Materials, 2019 AbstractWhile most photomechanical materials developed to date have relied on free‐space illumination to drive actuation, this strategy fails when direct line‐of‐site access is precluded. In this study, waveguided light is harnessed by liquid crystal elastomer (LCE) nanocomposites to drive actuation.
