摘要
综述了纤维素衍生物胆甾型溶致液晶及含胆甾型液晶结构的纤维素衍生物的复合物的结构研究的进展。纤维素衍生物能在多种溶剂中形成胆甾型溶致液晶 ,其液晶相具有多重织构特性 ,即它的多种织构的存在与外界条件如溶液的浓度、温度等有很大关系。在纤维素衍生物的胆甾型液晶溶液中还可观察到多种向错结构。含纤维素衍生物的高分子复合物的合成一方面使纤维素衍生物胆甾型液晶结构的研究进入了更微观的层次 。
The research in cholesteric structures of cellulose derivative liquid crystals has been reviewed in this article. Cellulose derivatives could form lyotropic liquid crystals in many organic solvents and the multi texture, which was influenced by the concentration and the temperature of the solutions, and the disclinations existed in cellulose derivative liquid crystals. The structural features of the cholesteric phase were revealed by directly observing the morphology and structure of the composites with cholesteric order.
