太阳帆是十分有利于深空探测的一种新型飞行器，帆面采用超轻薄的薄膜材料，提高飞行器的推进性能。帆面材料长期暴露在空间，由于长期受到空间粒子辐射环境的影响，性能发生退化影响在空间的应用。研究空间电子与薄膜相互作用的机理，分析电子沉积剂量，通过地面模拟不同剂量的空间电子辐照环境，对辐照后新型超薄帆面材料力学性能的研究，满足太阳帆在空间应用要求。结果表明：超薄聚酰亚胺薄膜材料，在厚度及辐照力学性能得到了较大的突破，但断裂伸长率仍需提升，电子辐照后性能略有下降，耐辐照性能也需进一步提高。

Solar sail is a new kind of spacecraft for deep space exploration.The ultra lightweight and thin membrane material are used to promote the spacecraft propulsion.Solar sail would stay in space for a long time, and the performance of sail membrane would decrease under the influence of the space radiation .The interaction mechanism between electron and sail material is discussed.Also, radiation dose that deposited in material by electrons is analyzed.After exposure to different electron radiation doses, the mechanical are investigated and their ability to meet demand for space applications is analyzed. Result shows that ultra thin polyimide film get a great accomplishment in thickness and mechanical properties before its expo-sure to electrons, but the elongation before break still need a promotion.Mechanical performance has decreased after electron exposure, and improvement in irradiation-resistance is also needed.
