摘要
通过降低胆甾相混合液晶配方中胆甾烯基油烯基碳酸酯的含量及适当改变胆甾烯基氯的含量，获得了 １０℃～５０ ℃范围内、变色温度梯度为１ ℃、变色范围从蓝色→绿色→红色的一系列胆甾相混合液晶。当配方中胆甾烯基氯含量超过 ２０％ 以上时，混合液晶的显色顺序颠倒。同时，对此类混合液晶的微囊化技术及形成机理进行了讨论。
A number of thermochromatic cholesteryl liquid crystal mixtures, of which the thermochromatic temperature gradient was 1 ℃ in the range of 10 ℃ to 50 ℃, were prepared by decreasing the content of cholesteryl oleic carbonate and properly changing the content of cholesteryl chloride in the composition of liquid crystal mixtures. The experiments showed that the thermochromatic order is reversed when the content of cholesteryl chloride exceeded 20 percent in mass. Also, the microcapsulizing of the prepared thermochromatic cholesteryl liquid crystal mixtures and the formation mechanism were discussed.
