| 摘 要： | 利用自制装置研究了脂环族环氧树脂(CER)/三羟甲基丙烷三甲基丙烯酸酯(TMPTMA)互穿网络聚合物(IPNs)的固化过程.通过在线测试CER/TMPTMA体系固化过程中的交流电阻和电容,发现电阻和电容的变化反映出CER/TMPTMA体系的固化过程是一个分步IPNs的形成过程,而且电阻和电容变化趋势与体系的粘度、离子浓度以及偶极子的数量息息相关.利用自制电极和装置可以远距离在线监测热固性树脂的固化过程,在外磁场干扰下,利用CER/TMPTMA固化体系的电阻波动可以表征体系的固化反应情况.

| Abstract: | The curing process of interpenetrating polymer networks(IPNs) based on cycloaliphatic epoxy resin(CER) containing cyclohexene oxide groups and tri-functional acrylate,trimethylol-1,1,1-propane trimethacrylate(TMPTMA) is studied.It is found that the changes in resistance and capacitance of CER/TMPTMA IPNs reflect the formation of sequence interpenetrating polymer networks during the curing process of CER/TMPTMA system and they are related rigidly to viscosity,ion content and dipole amount of CER/TMPTMA syste... |
