摘　　要：原子氧是低地球轨道主要的残余气体粒子,其化学性质非常活泼,是极强的氧化剂,会对空间材料的性能产生严重的影响。介绍了低地球轨道的原子氧环境及原子氧防护方法;对有机、无机和复合原子氧防护涂层的优缺点、研究进展情况以及空间应用情况进行了详尽的阐述;最后分析了原子氧防护的发展方向。The atomic oxygen（AO）is one of the most important factors in low earth orbit（LEO）environment.Chemical property of AO is very active,and can oxide most of polymeric materials.Spacecraft polymeric materials can be significantly eroded as a result of exposure to atomic oxygen in LEO.The paper provides an overview of the recent developments in AO environment and AO protection methods.The advantage,disadvantage and research progress of organic,inorganic and hybrid coatings are discussed.Further development trends are proposed.
