Abstract
Ferroelectric liquid crystalline polymethylsiloxane with side chains as mesogenic units was synthesized and characterized by polarized microscopy. These compounds are found to show smectic phase in mesophase region and exhibit spontaneous polarization. Spontaneous polarization (Ps) of PS8 is 127 nC/cm2 at 30.6 degree(s)C, and its response time is 15 ms at 86.4 degree(s)C. Optic devices are prepared by sandwiching the liquid crystal polymers (LCP) or LC/LCP in between the two ITO layers and their phase transitions are studied. Two stable textures of LC/LCP composite films are formed during different thermal treatments and the films can be applied as an optic memory medium.
