摘　　要：环氧树脂因耐腐蚀性强、耐热性好、力学强度高及电绝缘性能优异等优点,被广泛应用于核工业、高能加速器以及深太空探索领域。而这些应用环境中的电离辐射将破坏环氧树脂的三维网状结构,严重影响服役性能,这对其可靠性评估提出严峻地考验,因此,阐明辐射损伤行为成为必然需求。本文综述了近些年来关于环氧树脂辐射损伤的研究进展,重点分析了不同辐照条件下的交联和裂解反应对环氧树脂化学结构及性能(力学性能、热稳定性、导热性能、电气性能等)的影响。最后,结合目前环氧树脂辐射损伤研究方面存在的不足,展望了未来需要着重关注的研究方向。Epoxy resins are extensively utilized in the nuclear industry,high-energy accelerators,and deepspace exploration due to their strong corrosion resistance,good thermal stability,high mechanical strength,and exceptional electrical insulation properties.However,ionizing radiation present in these application environments can degrade the three-dimensional network structures of epoxy resins,significantly impacting their service performance.This presents a significant challenge for reliability assessment,making it necessary to elucidate their irradiation damage behavior.This paper reviews the recent research advancements on the radiation damage behavior of epoxy resins, emphasizing the effects of chain crosslinking and scission induced by various irradiation conditionson their chemical structures and physical properties, including mechanical properties, thermal stability, thermalconductivity, and electrical properties. Finally, future research directions deserving special attention are discussed,considering the current gaps in understanding the radiation damage in epoxy resins.
