Curing reaction and phase change in a liquid crystalline monomer

摘要

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. References: 25
