本文利用偏光显微镜、电镜、小角激光光散射(SALS)和X-射线衍射仪研究了乙基醋酸纤维素溶致性液晶态从非平衡到平衡过程的转变,同时研究了从液晶态结晶的固体形态。在两玻片之间受力的液晶溶液,需要一定的时间才能重新形成。主要以带状和球晶的形态存在,溶剂挥发以看,部分球晶发生变化,还观察到各区域的取向结构,并证实了从液晶态结晶的晶型与各向同性溶液结晶的晶型相同,但完整度不同。 In this paper, the transition from unbalanced to equilibrium state of lyotropic liquid crystal phase of ethyl cellulose acetate was studied by polarized light microscope, electron microscope, SALS and X-ray diffractometer. Meanwhile, form. A liquid crystal solution that is forced between two slides takes time to reform. Mainly in the form of ribbons and spherulites. When the solvent was volatilized and some spherulites changed, the orientation structure of each region was also observed, and the crystal form crystallized from the liquid crystal state and the crystal form crystallized from the isotropic solution were confirmed The same, but different degrees of completeness.
