The calculated values of spontaneous polarization, response time and rotational viscosity were found ~ 240nC/cm2, 20nC/cm2, 1600μs, 500μs, 230kg/ms and 19kg/ms for high and low polarization ferroelectric liquid crystalline materials, respectively. For the ferroelectric liquid crystal with high polarization, the effect of temperature, frequency and bias field on the dielectric properties have been studied and the obtained results were compared to those obtained on the ferroelectric liquid crystalline mixture with low spontaneous polarization.
