Design of Chemically Recyclable Nanocellulose Chiral Liquid Crystal Photonic Elastomer Vitrimer and its Mechanosensitive Colour-changing Materials [PDF]

open access: yesBioResources, 2023
The development of nanocellulose (CNCs) chiral liquid crystal photonic elastomeric vitrimer materials is promising for achieving needed reduction in carbon emissions (elastomer material recycling) and developing novel photonic functional materials.

Liquid Crystal Elastomer Waveguide Actuators [PDF]

open access: yesAdvanced 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.

Coincident molecular auxeticity and negative order parameter in a liquid crystal elastomer [PDF]

open access: yesNature Communications, 2018
Auxeticity in synthetic materials is realised by geometrical design of porous structures rather than on a molecular level. Here the authors demonstrate auxeticity in a non-porous liquid crystal elastomer overcoming porosity related weakening of the ...

Environmental Disturbance Effects on Liquid Crystal Elastomer Photothermal-Oscillator Dynamics [PDF]

open access: yesMathematics
Self-oscillations convert ambient energy into continuous periodic motion through feedback mechanisms, but their response to external periodic disturbances is not yet fully understood.

Polymer-dispersed liquid crystal elastomers [PDF]

open access: yesNature Communications, 2016
AbstractThe need for mechanical manipulation during the curing of conventional liquid crystal elastomers diminishes their applicability in the field of shape-programmable soft materials and future applications in additive manufacturing. Here we report on polymer-dispersed liquid crystal elastomers, novel composite materials that eliminate this ...

Liquid crystal elastomer coatings with programmed response of surface profile [PDF]

open access: yesNature Communications, 2018
Liquid crystal elastomers are anisotropic rubbers which can be actuated by an external trigger. Here the authors develop elastomer coatings with pre-patterned molecular orientation that induces deterministic topography changes in response to changes in ...

Toward Programmed Complex Stress-Induced Mechanical Deformations of Liquid Crystal Elastomers [PDF]

open access: yesCrystals, 2020
We prepare a liquid crystal elastomer (LCE) with a spatially patterned liquid crystal director field from an all-acrylate LCE. Mechanical deformations of this material lead to a complex and spatially varying deformation with localised body rotations ...

Leaping liquid crystal elastomers

open access: yesScience Advances, 2023
Snap-through mechanisms are pervasive in everyday life in biological systems, engineered devices, and consumer products. Snap-through transitions can be realized in responsive materials via stimuli-induced mechanical instability. Here, we demonstrate a rapid and powerful snap-through response in liquid crystalline elastomers (LCEs).
