Functionalize of Atomic Oxygen Durability for the Inflatable Structure Materials on Low Earth Orbit

用于纳米卫星脱轨装置的充气结构材料具有较高的抗原子氧性能。对充气结构材料的热密封性能、抗紫外线和带电粒子辐射的耐久性也有要求。然而，没有一种材料具有所需的性能。在本研究中，我们试图通过后处理的方法诱导出F、Si、P等原子，使材料对广泛用于航天的聚酰亚胺的化学结构具有原子氧抵抗性。结果，原子给予原子氧的阻力在加工材料上被检测到。因此，我们可以期望加工材料具有高的原子氧抗性。

The high atomic oxygen resistance is required on the inflatable structure materials used for the nano-satellite deorbit device. The heat seal property and the durability against ultraviolet ray and charged particle radiation are also required on the inflatable structure materials. However, there is no material having the required properties.In this study, we tried to induce a F, Si, P, and etc. atom that gave the materials the atomic oxygen resistance to a chemical structure of polyimide widely used for space by using post process. As a result, the atom gave the atomic oxygen resistance was detected on the processed materials. Therefore, we could expect the high atomic oxygen resistance on the processed materials.
