Liquid crystal elastomers wrinkling [PDF]
Nonlinearity, 2021 Abstract When a liquid crystal elastomer layer is bonded to an elastic layer, it creates a bilayer with interesting properties that can be activated by applying traction at the boundaries or by optothermal stimulation. Here, we examine wrinkling responses in three-dimensional nonlinear systems containing a monodomain liquid crystal ...

Aggregation-Induced Emission Luminogen-Functionalized Liquid Crystal Elastomer Soft Actuators [PDF]
, 2018 An aggregation-induced emission (AIE)-active liquid crystal elastomer (LCE) soft actuator is fabricated through chemical incorporation of a four-alkenyl-armed tetraphenylethene-core cross-linker into a main-chain LCE matrice by a facile in situ two-step ...

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.

Wearable perovskite solar cells by aligned liquid crystal elastomers
Nature Communications, 2023 The bottom interface between perovskite and electron-transporting layer is critical for realizing efficient flexible perovskite solar cells. Here, the authors intercalate liquid crystal elastomer interlayer for aligned mesogenic assembly and achieve ...

Programmable liquid crystal elastomer microactuators prepared via thiol–ene dispersion polymerization [PDF]
, 2020 Narrowly dispersed, 10 micron-sized, liquid crystalline elastomer polymer actuators were first prepared via thiol–ene dispersion polymerization and then embedded and stretched in a polyvinyl alcohol film, followed by photopolymerization of the residual ...
