The experiment was carried out with a combination of polymer-coated quartz crystal microbalance and high-speed chopper wheel in the laser-detonation atomic oxygen source. It was clearly observed that the mass-loss rates of both polyimide and fluorinated polymer strongly depend on the impact energy of atomic oxygen. However, the effect was more significant on fluorinated polymer compared with that on polyimide; i.e., translational energies higher than 6 eV provide a significant mass-loss on fluorinated polymer. This experimental finding agrees with the volatile product data and theoretical predictions. It was confirmed that the presence of high-energy component in atomic oxygen beams resulted in the increase of mass-loss rate on fluorinated polymer relative to polyimide., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064933023, レポート番号: JAXA-SP-10-013}, pages = {179--183}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Nonlinear energy dependencies under the atomic oxygen-induced erosion of fluorinated polymers}, volume = {JAXA-SP-10-013}, year = {2011} }
