Elasticity of Polydomain Liquid Crystal Elastomers

open access: yes, 2011
We model polydomain liquid-crystal elastomers by extending the neo-classical soft and semi-soft free energies used successfully to describe monodomain samples. We show that there is a significant difference between polydomains cross-linked in homogeneous

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]

open access: yes, 2003
Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.
