Elastic effects in disordered nematic networks.

چکیده

Elastic effects in a model of disordered nematic elastomers are numerically investigated in two dimensions. Networks crosslinked in the isotropic phase exhibit an unusual soft mechanical response against stretching. It arises from a gradual alignment of orientationally correlated regions that are elongated along the director. A sharp crossover to a macroscopically aligned state is obtained on further stretching. The effect of random internal stress is also discussed.

External and intrinsic anchoring in nematic liquid crystals: a Monte Carlo study.

We present a Monte Carlo study of external surface anchoring in nematic cells with partially disordered solid substrates, as well as of intrinsic anchoring at free nematic interfaces. The simulations are based on the simple hexagonal lattice model with a spatially anisotropic intermolecular potential. We estimate the corresponding extrapolation length b by imposing an elastic deformation in a h...

بلورهای مایع در بر دارنده ی نانو ذرات و نیرو های القایی

After a short review of nematic liquid crystals and their interactions with the external fields, we investigate the effect of a disordered field which destabilizes the orientational molecular order of a nematic film. We analyze the effect of the disorder in the applied field on the pseudo-Casimir force which is induced due to thermal fluctuationsbetween the confining walls of the nematic film. ...

Isotropic-nematic transition of surface embedded polymers and the associated tubulization transition of the embedding surface.

A self-interacting polymer can undergo an orientational ordering transition, depending on the magnitude of the nematic interaction. The effect of embedding such a polymer into a flexible surface on this transition is studied on the mean-field level. Renormalized values of the elastic constants of the ‘‘dressed’’ surface are derived as functions of the orientational order parameter of the polyme...

Tube Model for the Elasticity of Entangled Nematic Rubbers

Dense rubbery networks are highly entangled polymer systems, with significant topological restrictions for the mobility of neighbouring chains and crosslinks preventing the reptation constraint release. In a mean field approach, entanglements are treated within the famous reptation approach, since they effectively confine each individual chain in a tube-like geometry. We apply the classical ide...

Role of elastic effects in the secondary instabilities of the nematic-isotropic interface

We show expenmentally that certain secondary instabilities of the nematic-isotropic interface depend both on the topology of the disclmation line which is pinned to the meniscus and on the elastic amsotropy of the matenal chosen
