Paper Abstract

THe present work has involved a fragment of our studies on phase separation processes in polymer-liquid crystal systems. We have studied the relationship between morphology and thermo- and electro-optical properties of liquid crystal - polymer composite materials achieved by SIPS method. The PDLC materials consists of the nematic liquid crystal of 20 to 60 percent weight fraction dispersed in amorphous polycarbonate. The PDLC films were prepared by casting from solution in methylene chloride. The result show that about 35 percent of the initial content of LC stays dissolved in the polymer matrix affecting its glass transition temperature. The PDLC samples exhibit good electrooptical properties in the case when the initial LC content is higher than 20 percent by weight. The threshold voltage is ranges from 10 to 20 V.
