Outline of Final Research Achievements

The purpose of this study is to construct the fundamental technology to create high space environment resistive materials by using after-treatment material improvement technology to improve resistivity of atomic oxygen.
As a result of our surface improvement treatment, we confirm high atomic oxygen resistivity on polyimide material. There are no change on the mechanical and thermo-optical properties of the polyimide material processed by using atomic oxygen resistivity improvement technique. In addition to this, There is no change on the radiation resistivity before and after processing. Therefore we concluded the technology of atomic oxygen resistivity improvement is useful, although the material improvement is localized near the surface of a material.
