摘　　要：低地球轨道环境中的原子氧具有高通量和强氧化性,会快速侵蚀航天器表面的聚酰亚胺材料,造成材料严重失效。针对聚酰亚胺材料抵抗原子氧侵蚀能力不足的问题,国内外研究人员积极探索,已提出多种抗原子氧防护技术,这些技术方案可分为包覆法、基体调控和外加涂层防护三个方面。此外,本文还整理了计算模拟探究抗原子氧防护效果的主要策略,指出计算与实验相结合有助于提高材料模型的准确性以及对抵抗原子氧侵蚀效果的预测能力。本文结合航天工程的实际应用,合理分析这三类防护措施的优势与不足,系统总结出不同聚酰亚胺基复合材料的抗原子氧防护性能。最后,对聚酰亚胺材料抗原子氧防护技术的研究工作进行总结,并展望了未来发展趋势。Atomic oxygen(AO)in low earth orbit environment has high flux and strong oxidizing properties.It can erode rapidly the polyimide on the surface of the spacecraft,causes serious material failure.Researchers have explored many positive solutions to the problem of weak AO resis-tance of polyimide,and there are three main types of these technical approaches,i.e.cladding blanket,matrix modification and coating protection.Besides,the main strategies for numerical simulation technique of AO resistant effect were also summarized.It showed that combination of simulation and experiment could improve the model accuracy and the predictive ability of AO resistant effect.In this work,the advantages and disadvantages of these solutions were analyzed according to the aerospace engineering,and then we systematically summarized resistance abilities of different polyimide materials.Overall,we summed up the AO resistant techniques of polyimide materials clearly and prospected their future development tendency.
