コレステロール誘導体をメソゲン基とする側鎖型キラルスメクチックＡ液晶エラストマーの相転移挙動と電界誘起変形

抄録

Mechanical responses to electric stimulation in a side-chain chiral smectic A elastomer composed of cholesterol derivative mesogens are investigated. An electric-field-induced shear deformation, caused by the electroclinic effect, is recognized in the chiral smectic A phase with a wide temperature range between 40°C and 120°C. In addition, an electric-field-induced bend deformation is confirmed in the temperature region of the isotropic state.
