Thermodynamic and dielectric spectroscopy of a racemic antiferroelectric liquid crystal

► Thermodynamic and optical studies provide phase transition temperatures and phase sequences. ► Material contains various phases: SmC and SmCA. ► Range of the dielectric spectroscopy of the material: 0.1 Hz to 10 MHz. ► Various relaxation mechanisms have been found in various phases of the material. ► Racemic AFLCs are expected to be better over surface stabilized FLC and AFLC cells for displays.
