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.

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 ...

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.

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.

Enabling liquid crystal elastomers with tunable actuation temperature
Nature Communications, 2023 Liquid crystalline elastomers are regarded as a kind of desirable soft actuator material for soft robotics and other high-tech areas. The isotropization temperature (Ti) plays an important role as it determines the actuation temperature and other ...

Supersoft elasticity in polydomain nematic elastomers [PDF]
, 2009 We consider the equilibrium stress-strain behavior of polydomain liquid crystal elastomers (PLCEs). We show that there is a fundamental difference between PLCEs cross-linked in the high temperature isotropic and low temperature aligned states.

Thiol–acrylate side-chain liquid crystal elastomers
Soft Matter, 2022 The Michael addition ‘click’ chemistry was used to graft acrylate-terminated mesogenic groups onto the polysiloxane backbone polymer chain with thiol functional groups, with a constant 15% fraction of diacrylate reacting monomers as crosslinkers.

Polymer-dispersed liquid crystal elastomers as moldable shape-programmable material
Nature Communications, 2023 Development of Soft shape-memory materials is often limited to the synthesis of two-dimensional specimens and rely on bending mechanisms and scaffolding topology to perform three-dimensional morphing.

Nonlinear Elasticity, Fluctuations and Heterogeneity of Nematic Elastomers
, 2007 Liquid crystal elastomers realize a fascinating new form of soft matter that is a composite of a conventional crosslinked polymer gel (rubber) and a liquid crystal. These {\em solid} liquid crystal amalgams, quite similarly to their (conventional, fluid)
