原子氧作用下导电黑膜性能退化研究

摘要

The atomic oxygen is one of the most important space environments in the LEO space,which could dam-age the spacecraft materials due to its huge erosion effect. The antistatic black polyimide films are the stray light removing materials and antistatic materials,and usually used to the satellite antenna and the spacecraft surface material. This paper presents experimental investigations of antistatic black polyimide films damaged by atomic oxygen. Study of the perfor-mance degeneration rules of antistatic black polyimide films,The atomic oxygen durability of the antistatic black poly-imide films on the LEO were studied for preliminary. Some reasonable proposals are given for the LEO mission design of the antistatic black polyimide films.%原子氧环境是影响低地球轨道（LEO）航天器材料性能的主要空间环境因素之一，其强氧化性能够对材料造成危害。镀膜型导电黑色聚酰亚胺薄膜（简称导电黑膜）具有良好的消杂光和防静电特性，是常用的卫星天线和整星表面的防护材料。本文通过开展国外替代产品导电黑膜原子氧模拟实验，研究原子氧作用下导电黑膜的性能退化。初步探索了我国导电黑膜低轨原子氧环境适应性，为我国导电黑膜低地球轨道应用提供建议。
