在无磁场和10 T磁场下固化液晶环氧树脂，分别得到多畴和单畴网络。这些系统的断裂韧性进行了评估，并澄清，磁场系统的韧性表现出较高的值。为了研究增韧机理，进行了偏振显微FTIR测量。因此，澄清了它们的机制完全不同。© 2006 Wiley Periodicals，Inc.聚合物科学杂志B部分：聚合物物理44：1406-1412，2006
A liquid crystalline epoxy resin was cured under non- and 10T-magnetic fields, and polydomain and monodomain networks were obtained, respectively. The fracture toughness of these systems was evaluated and it was clarified that the toughness of the magnetic field system showed a higher value. To investigate the toughening mechanism, polarized micro FTIR measurements were carried out. As a result, it was clarified that their mechanisms were quiet different. © 2006 Wiley Periodicals, Inc.
