Polyimide has also been used as a reference material to measure atomic oxygen fluence in LEO. Erosion properties of polyimide by hyperthermal impact of atomic oxygen under various synergistic exposure conditions need to be well understood for an accurate fluence measurement. In this study, the effect of surface charging on the atomic oxygen-induced erosion of polyimide was studied. The erosion rates of polyimide were not altered by bias voltages up to +/- 1,000 V under 4.8 eV atomic oxygen exposure condition. In contract, 20 percent increase in erosion rate was observed by 1.1 eV atomic oxygen beam exposure. It was confirmed that the effect of surface charging on the erosion of polyimide depends on the translational energy of impinging atomic oxygen., 資料番号: AA0049206060, レポート番号: JAXA-SP-05-001E}, pages = {545--549}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Atomic oxygen-induced erosion of polymeric materials under surface charging condition}, volume = {JAXA-SP-05-001E}, year = {2005} }
