摘要
用偏光显微镜研究了一种新的液晶高分子—丁酸壳聚糖液晶的织构。丁酸壳聚糖能溶于十多种溶剂中形成胆甾型液晶相。指纹状织构是主要织构，此外还观察到鲜偏振场织构、滴状织构、平面织构和条带织构等，与纤维素衍生物的液晶态结构很相似。
Texture of a new liquid crystalline polymer—butyryl chitosan was studied using polarized microscopy.Butyryl chitosan can form cholesteric liquid crystalline phase by dissolving in more than ten solvents.The major texture was fingerprint texture.Alternative polarized field,droplet texture,granular texture,plannar texture and banded texture were also found.The liquid crystalline texture of butyryl chitosan is similiar to that of cellulose derivatives.
