碩士 === 元智大學 === 化學工程學系 === 91 === To study the properties of ferroelectric liquid crystal FLC2B11C and FLC11C, we used not only polar optical microscopic (POM), differential scanning calorimeter (DSC), dielectric analysis (DEA) to get the phase-change temperature of liquid crystal, but also POM to observe its texture. We also utilized Saywer-Tower method to measure spontaneous polarization (Ps) of ferroelectric liquid crystal, to discuss the temperature’s dependence on PS, tilt angle and response time, and to discover the connection with Ps, response time and title angle. We studied the molecular motion of LC and the changes of transmittance in the electric field by means of the analysis of transmittance and POM observation.
