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

纳卫星离轨装置所用的充气结构材料要求具有较高的抗原子氧性能。对充气结构材料还要求具有热密封性和抗紫外线和带电粒子辐射的耐久性。但是，目前还没有具备所需性能的材料。本研究中，我们尝试通过后处理（post process），在广泛应用于太空的聚酰亚胺的化学结构中引入F、Si、P等原子，使材料具有原子氧抗性。结果，在加工材料上检测到产生原子氧电阻的原子。因此，我们可以预期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.
