Spontaneous polarization and response time of polymer dispersed ferroelectric liquid crystal (PDFLC)

Abstract

Results reported on the spontaneous polarization, switching time and rotational viscosity measurement of a FLC compound in neat phase and that in polymer matrix in the present paper. Polymer-dispersed ferroelectric liquid crystal film was formed by photopolymerization due to polymerization induced phase separation. A detailed study has been made on the spontaneous polarization, switching time at different temperatures and measuring field. It has been observed that the magnitude of spontaneous polarization of the PDFLC mixture is not in accordance with their mixing ratio. The switching time in PDFLC mixture is less than that in neat FLC mixture.
