碩士 === 元智大學 === 化學工程研究所 === 88 === An induced smectic phase was obtained by mixing two kinds of nematic liquid crystals with strong and weak end groups, respectively. This ISP was then mixed with one ferroelectric liquid crystal, and its thermal properties and electro-optic behaviors were observed. Results showed that the composite was bistable, and had only one liquid crystal phase. Another composite HPPB/E44/CS1014 changed colors with varying temperature in thin cell; while in thick cell, it displayed a special chiral nematic phase.The bistable property is available in memory effect, and colors change with temperature is also fun in art or display.
