Liquid crystal elastomers [PDF]

, 2011
The graduation work presents liquid crystal elastomers (LCE), which are made from liqid crystals and elastomers. Their main microscopic properties are orientation, positional order and the smectic order to the layer normal.

Instabilities in liquid crystal elastomers [PDF]

MRS Bulletin, 2021
Stability 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 ...

Thermomechanical response of liquid crystal elastomers: role of crosslinker density

Materials Research Express
In this work thermomechanical properties of main-chain liquid crystal elastomers (MC-LCEs) with different degrees of crosslinking were investigated, and gradual loss of thermomechanical response was observed on repetitive measurements.

Dynamic Self-Stiffening in Liquid Crystal Elastomers [PDF]

Nature 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

Influence of the porosity on the photoresponse of a liquid crystal elastomer [PDF]

Royal Society Open Science, 2016
Azobenzene containing liquid crystal elastomers (LCEs) are among of the most prominent photoresponsive polymers due to their fast and reversible response to different light stimuli.
