Analysis of Thermalresponsive of Periodic Surface Undulation of Cholesteric Liquid Crystal Elastomers

Abstract

Liquid crystal elastomers are unique materials with the strong coupling of molecular orientation and macroscopic shape. Cholesteric liquid crystal elastomers (CLCEs), whose helical axis is parallel to a direction in the film plane, have a thermoresponsive and periodic surface-undulation with a period corresponding to a half-pitch of the helical director configuration.
