Strain Analysis of a Chiral Smectic A Elastomer
Christopher M. Spillmann, John H. Konnert, James M. Adams +3
We present a detailed analysis of the molecular packing of a strained liquid crystal elastomer composed of chiral mesogens in the smectic A phase. X-ray diffraction patterns of the…
Critical Field Strength in an Electroclinic Liquid Crystal Elastomer
Christopher M. Spillmann, Amit V. Kapur, Frank W. Bentrem +2
We elucidate the polymer dynamics of a liquid crystal elastomer based on the time-dependent response of the pendent liquid crystal mesogens. The molecular tilt and switching time o…
Isotropic-Nematic Transition in Liquid-Crystalline Elastomers: Lattice Model with Quenched Disorder
Jonathan V. Selinger, B. R. Ratna
When liquid-crystalline elastomers pass through the isotropic-nematic transition, the orientational order parameter and the elastic strain vary rapidly but smoothly, without the ex…
Shape Selection in Chiral Self-Assembly
Robin L. B. Selinger, Jonathan V. Selinger, Anthony P. Malanoski +1
Many biological and synthetic materials self-assemble into helical or twisted aggregates. The shape is determined by a complex interplay between elastic forces and the orientation…
Chiral and Antichiral Order in Bent-Core Liquid Crystals
Jonathan V. Selinger
Recent experiments have found a bent-core liquid crystal in which the layer chirality alternates from layer to layer, giving a racemic or "antichiral" material, even though the mol…
Simulations of Helix Unwinding in Ferroelectric Liquid Crystals
Nurit Baytch, Robin L. B. Selinger, Jonathan V. Selinger +1
In bulk ferroelectric liquid crystals, the molecular director twists in a helix. In narrow cells, this helix can be unwound by an applied electric field or by boundary effects. To…
