Paper Abstract

Chiral smectic C (SmC*) elastomers have attracted both industrial and scientific interests, because of rubber elasticity with anisotropic physical properties such as pyroelectricity, ferroelectricity, SHG and piezoelectricity owing to the point group C2. In this paper, we discuss their physical properties focused on the stimuli-responsive behavior, such as the biaxial shape memory effect in thermo-mechanical responses, the electric response to mechanical excitation due to the piezoelectric effect, and the electroclinic effect that brings about macroscopic deformation. Additionally, we consider chiral mechanical coupling between tilt and twist in SmC* elastomers.
