| 摘 要： | 以乙基纤维素／丙烯酸体系为例，对乙基纤维素液晶的胆甾相性质及其影响因素进行了研究，测定了体系胆甾相结构的螺距。结果表明，乙基纤维素／丙烯酸液晶体的螺旋方向为左旋，随溶液液浓度的增大，胆甾相结构的螺距减小。胆甾相结合的螺距还明显地受到温度，压力、溶剂组成，高分子掺杂等因素的影响。

| Abstract: | In the typical case of ethylcellulose/ acrylic acid (EC / AA) system, cholesteric (helical) Properties and the influence factors of ethylcellulose liquid crystals were studied. It has been found that the sense of EC / AA system was left-handed. Pitches of cholesteric structure were measured, which decreased with the increase of concentration of EC/ AA solution. Cholpsteric properties of EC liquid crystals were influenced also significantly by temperature, pressure, composition of solvent and mixing with other Polymer. |
