In this study UV absorption, textures and electro-optical study have been performed for pure ferroelectric liquid crystal (FLC) and its three different concentrations, i.e., 1%, 3% and 5% of polymer in pure FLC. I observed that there is a higher value of UV absorption for polymer doped system in comparison to the pure system. The higher value of spontaneous polarization and faster response has been observed for polymer doped system compared to the pure FLC system. The important electro-optical parameters like spontaneous polarisation, response time and tilt angle have been calculated and plotted with variation of applied voltage. The tilt angle is an intrinsic property of an FLC material, which is hardly affected by the presence of dye molecules and hence studies showing such observations are rare. The electro-optical study suggests that there exists an optimum concentration of polymer for which I have found highest spontaneous polarisation and least response time.
