摘要
本文通过偏光显微镜、DSC、X射线衍射及选择散射等手段,深入研究了甲基丙烯酸羟乙酯胆甾醇甲苯二异氰酸酯接枝共聚物的相态转变。在一定的条件下,侧链上的胆甾基团可自由取向,形成胆甾相液晶。
In this paper, the phase transition of PHCEM has been studied by optical micro-scope, DSC, choose scattering and X--ray diffraction. In a certain condition, thecholesteric groups in the side chain can take an oriented arrangement, and a cholestericliquid crystalline phase is formed.
