Liquid Crystals

2006
Abstract This article discusses modern directions of research in liquid crystals (LCs). LCs represent one of the best studied classes of soft matter, along with colloids, polymer solutions and melts, gels, and foams. Phenomena observed in LCs and approaches developed for their description become of heuristic value in other branches of ...

Interpenetrating Liquid Crystal Polyurethane/Polyacrylate Elastomer with Ultrastrong Mechanical Property.

Journal of the American Chemical Society, 2019
Liquid crystal elastomer (LCE) materials, which have been developed and investigated for four decades, still lack real industrial applications. The fundamental obstacle is the modest force of LCEs generated in the LC-to-isotropic phase transition process,

Liquid Crystals Align Liquid Crystals

Japanese Journal of Applied Physics, 2002
We have investigated the molecular orientation of a liquid crystal (LC), pentylcyanobiphenyl (5CB), evaporated on a rubbed polymer by means of polarized ultraviolet absorption spectroscopy and surface second-harmonic generation. The results unambiguously reveal that the in-plane anisotropy is diminishingly small before the molecules form a monolayer ...

Nature‐Inspired Emerging Chiral Liquid Crystal Nanostructures: From Molecular Self‐Assembly to DNA Mesophase and Nanocolloids

Advances in Materials, 2018
Liquid crystals (LCs) are omnipresent in living matter, whose chirality is an elegant and distinct feature in certain plant tissues, the cuticles of crabs, beetles, arthropods, and beyond. Taking inspiration from nature, researchers have recently devoted

Liquid crystal elastomers: an introduction and review of emerging technologies

, 2018
Liquid crystal elastomers (LCEs) are a unique class of materials that combine rubber elasticity with liquid crystalline anisotropy to produce exceptional physical and optical properties such as actuation, soft elasticity, and birefringence.

Four-dimensional Printing of Liquid Crystal Elastomers.

ACS Applied Materials and Interfaces, 2017
Three-dimensional structures capable of reversible changes in shape, i.e., four-dimensional-printed structures, may enable new generations of soft robotics, implantable medical devices, and consumer products.

A Fluid Liquid‐Crystal Material with Highly Polar Order

Advances in Materials, 2017
An anomalously large dielectric permittivity of ≈104 is found in the mesophase temperature range (MP phase) wherein high fluidity is observed for a liquid‐crystal compound having a 1,3‐dioxane unit in the mesogenic core (DIO).
