摘要： 在微波电离型原子氧(AO)源地面模拟设备中对空间材料聚酰亚胺(Kapton)及有机硅防护层进行原子氧剥蚀效应试验.用光电子能谱(XPS)、红外光谱(FTIR)和扫描电镜(SEM)对试验前后试样的表面形貌、质量及化学结构进行表征研究.AO对Kapton表现了较严重的侵蚀作用,原来平整的表面形貌变为毛毯状;而所施用的有机硅涂层的表面形貌则变化甚少,表明该涂层具有较明显的防护效果.

Abstract: Kapton HN(PMDA-ODA, polyimide) has many applications in aerospace technology as solar cell blanket and thermal blanket. But Kapton is susceptible to atomic oxygen(AO) erosion. Exposure experiment ground-based simulation facilitYINdicate that it undergoes mass loss and surface degradation. XPS was used to characterize the chemical and physical change of the surface of Kapton after AO irradiation. Strong oxidative degradation of Kapton and substantial changes in surpermolecular organization and morphology of its surface layer were observed after AO irradiation. The results suggest that AO not only reacts with Kapton surfaces, but also the transfer of the energy of particle collisions of chain macromolecules in surface layer aids in the development of physicochemical reaction processes. It is evident that siloxane coatings have excellent properties for anti-AO effects.

Key words: Kapton, Atomic oxygen, Erosion, Protection
