The polymeric ferroelectric liquid crystals with two chiral groups, one on each side of the core, show large spontaneous polarization. We prepared ferroelectric liquid crystal copolymers containing the dichiral liquid crystal and a nonchiral liquid crystal. Copolymerization resulted in a chiral smectic C phase existing over a wide range of temperatures, including room temperature. Mixing the copolymers with low-molecular-weight liquid crystals further decreased the viscosity and improved the response time. The mixture responded to an electric field within a hundred milliseconds at room temperature.
