Elasticity of polydomain liquid crystal elastomers [PDF]

open access: yesJournal of the Mechanics and Physics of Solids, 2012
We model polydomain liquid-crystal elastomers by extending the neo-classical soft and semi-soft free energies used successfully to describe monodomain samples. We show that there is a significant difference between polydomains cross-linked in homogeneous high symmetry states then cooled to low symmetry polydomain states and those cross-linked directly ...

Polymer-dispersed liquid crystal elastomers as moldable shape-programmable material

open access: yesNature 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.

Thiol–acrylate side-chain liquid crystal elastomers

open access: yesSoft 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.

Impact damping and vibration attenuation in nematic liquid crystal elastomers

open access: yesNature Communications, 2021
Nematic liquid crystal elastomers (LCE). exhibit unique mechanical properties such as large loss behaviour, which makes these materials interesting for damping applications.

4D Printing of Freestanding Liquid Crystal Elastomers via Hybrid Additive Manufacturing

open access: yesAdvances in Materials, 2022
Liquid crystal elastomers (LCE) are appealing candidates among active materials for 4D printing, due to their reversible, programmable and rapid actuation capabilities. Recent progress has been made on direct ink writing (DIW) or Digital Light Processing

Dynamic self-stiffening in liquid crystal elastomers [PDF]

open access: yesNature 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 permanent increase in stiffness are uncommon. Here we report that polydomain nematic liquid crystal

Soft elasticity optimises dissipation in 3D-printed liquid crystal elastomers

open access: yesNature Communications, 2021
Soft-elasticity in monodomain liquid crystal elastomers (LCEs) is promising for impact-absorbing applications but due to the lack of synthetic procedures which give monodomain devices of sufficient size, impact studies on LCEs have not been performed ...

Environmentally Stable Chiral-Nematic Liquid-Crystal Elastomers with Mechano-Optical Properties

open access: yesApplied Sciences, 2021
Chiral-nematic liquid crystal (N* LC) elastomers exhibit mechano-optical responsive behavior. However, practical sensor applications have been limited by the intrinsic sensitivity of N* LC elastomers to environmental conditions, such as temperature ...
