摘　　要：以预聚物双酚A环氧树脂(E-44)和双酚A环氧丙烯酸酯(EA)为主要原料加入一定的单体和引发剂配制成混杂光固化树脂。运用FTIR、DMA、TG及TEM等手段,表征了混杂光固化材料的结构,讨论了环氧树脂含量对材料固化程度和结构变化的影响。结果表明,混杂光固化材料具有2个玻璃化转变温度,具有良好的阻尼性能及热温度性能。Hybrid UV-cured resins were prepared by using bisphenol A epoxy resin （E-44） and bisphenol A epoxy acrylate （EA） as the main raw materials with monomers and photoinitiators. The structure and properties of the hybrid UV-cured material were characterized with Fourier transform infrared spectrograph （FTIR）, dynamic mechanical thermal analysis （DMA）, thermogravimetric analysis （TG） and transmission electron microscopy （TEM）. The influence of the content of epoxy resin on the curing extent and structure was discussed. The results showed that the curing extent of the hybrid UV-cured material was not correlated with the content of the glass transition temperatures, good thermal stability epoxy resin. The hybrid UV-cured material had two and damping properties.
