Rheology of liquid crystalline polymers
Concepts which may be used in interpreting the complex rheology of liquid crystalline polymers are reviewed. Some of them are taken from the nematodynamics of low molecular weight liquid crystals as described by the Leslie—Ericksen theory, others are intrinsic to the viscoelasticity of ordinary polymers. Tentatively, these concepts are used to construct an explanation of the band texture which ...
متن کاملMain-chain smectic liquid-crystalline polymers as randomly disordered systems.
We report a high-resolution X-ray lineshape study of main-chain smectic polymers. The results indicate that the layer ordering differs fundamentally from the algebraic decay typical for other smectic liquid-crystalline systems. The lineshapes are best described by broad squared Lorentzians indicating some form of short-range correlations. However, several higher harmonics are observed, which ex...
متن کاملn liquid crystalline elastomer materials
Liquid crystalline elastomers (LCEs) exhibit a number of remarkable physical effects, including the unique, high-stroke reversible mechanical actuation when triggered by external stimuli. This article reviews some recent exciting developments in the field of LCE materials with an emphasis on their utilization in actuator applications. Such applications include artificial muscles, industrial man...
متن کاملLiquid Crystalline Acrylates and Their Polymers
In previous papers (1,2) the thermotropic properties and the kinetics of the bulk polymerization of the mesomorphic monomer cholesteryl acrylate have been described. In addition to cholesteryl acrylate, the methacrylate was prepared, as well as the respective acrylic methacrylic acid ester of cholestanol. We now wish to report the properties of these monomeric esters and the results of their po...
متن کاملPiezochromic fluorescence in liquid crystalline conjugated polymers.
Liquid crystalline diphenylacetylene polymer derivatives showed piezochromic fluorescence via order-to-disorder phase transition.
