摘要
利用偏光显微镜,对乙基纤维素/二氯乙酸(EC/DCA)胆甾相液晶的织构进行了研究。当EC/DCA液晶溶液处于两相共存状态时,可以观察到一种典型的胆甾相液晶织构形式——盘状聚集体。结合有效偶极矩模型,推断了分子链在盘状聚集体中的排列方式及盘状聚集体的二维等速生长性质。
In this article, the texture of ethylcellulose/dichloroacetic acid (EC/DCA )cholesteric liguid crystal was in vestigated by means of polarized light microscope, when EC/DCA liquid crystal solution is in biphase state,one typical cholesteric liquid crystal texture,disk-like aggregate,is observed through polarized light microscope. The molecular arrangement in disklike aggregate and its two dimensional equal-rate growth characteristic were deduced by using effective dipole-moment model. .
