Deformation–induced orientational transitions in liquid crystals elastomer
نویسندگان
چکیده
Solid liquid crystals, formed by crosslinking polymeric nematics into elastomers are shown to display novel and complex elasticity. The internal (nematic) direction can experience a barrier to its rotation which couples to standard elasticity. We investigate this elasticity by considering imposed strains and demonstrate several new orientational phase transitions, caused by the interaction between applied stress fields and bulk barriers to rotation.

A Mathematical Theory for Nematic Elastomers with Non-uniform Prolate Spheroids
We address some problems arising in the mathematical modeling of nematic elastomers with variable step length tensors and directors with non-uniform length (which represents, in turn, the nonuniform prolate spheroid shapes). Using a similar idea of the Ericksen theory for liquid crystals with variable degree of orientation, we introduce a non-unit vector, called the shape parameter, to describe...
متن کاملMagnetic field induced orientational transitions in liquid crystals doped with carbon nanotubes
We propose a continuum theory of orientational phase transitions induced by an external magnetic field in a suspension of carbon nanotubes in a nematic liquid crystal. It is shown that in a magnetic field a non-uniform and two different uniform phases are possible in the suspension. The uniform phases of the suspension differ by the type of orientational coupling of nanotubes with the liquid cr...

Orientation distributions in droplets of liquid crystals with homeotropic anchoring are computed with a simulated annealing algorithm that minimizes the free energy of the Oseen-Frank continuum theory. The droplets exhibit multiple orientational steady states that are separated by finite energy barriers over the entire range of the dimensionless ratio of surface to elastic forces, with maximum ...

متن کاملNematic ordering in anisotropic elastomers: Effect of frozen anisotropy
Nematic ordering in anisotropic non-Gaussian elastomers is considered theoretically using mean field approximation. We focus on the effect of anisotropy during network cross-linking on the system elasticity and, in particular, on the so-called soft deformation mode. As the main result, we calculate the dependence of the elastomer free energy on the angle between the axis of “frozen” anisotropy ...
