用三种不同的胺在液晶相中固化环氧单体形成（LCT）。采用差示扫描量热法（DSC）和广角x射线衍射研究了LCT的热跃迁。（WAXD）和偏振光学显微镜（POM）。根据固化剂和反应条件的不同，观察到不同的固化特征，这与固化过程中LC相的形成和发展有关。等转换分析用于表征固化过程。
An epoxy monomer was cured in liquid crystalline phase with three different amines to form (LCT). The thermal transitions of the LCT were studied by differential scanning calorimetry (DSC), wide angle X-ray diffraction. (WAXD) and polarized optical microscopy (POM). Different curing features are observed depending on the curing agent and reaction condition, which is related to the formation and development of LC phase during cure. An isoconversional analysis is used to characterize the cure process.
