摘要： 用X-射线衍射法详细研究了ChN/Poly(MMA-co-BMA)共混体系在胆笛(Ch)相,近晶(S)相及结晶(K)态的分子排列。并给出了将液晶态的分子排列冻结在体系中,从而实现信息存储功能的条件。

关键词: 胆甾液晶, 聚合物多组分体系, 信息存储材料, X－射线衍射

Abstract: The molecular orientation of crystalline and liqtiid crystalline states of poly (MMA-co-BMA) and ChN mixtures have been sttidied by X-ray diffraction. It was shown that the molecular orientation of smactic A liquid crystal can be frozen in the system at room temperature and the storage information was realized.

Key words: cholesteric liquid crystals, polymer dispersed liquid crystals, material of storageinformation, X-ray diffraction
