The influence of high-energy ion bombardment on chemical structures of non-metallic materials was investigated to clarify the mechanism of the material degradation in space. Polymers of polyimide, polyetherether-ketone and perfluoroalkoxy and glasses coated with MgF
2 were exposed to ion beams of oxygen and nitrogen with energy levels of 600eV-5keV, which were generated using an electron cyclotron resonance discharge ion accelerator. For the polymers, X-ray photoelectron spectroscopic analysis showed that both addition reactions of oxygen or nitrogen atoms and separations of various structural compounds occurred. In the glass plate, the coating layer of MgF
2 was sputtered drastically.
