It provides low solar absorptance (alpha(sub s)) and high infrared emittance (epsilon) with flexibility. The F-OSR, which has a conductive layer and a mirror layer coated onto a polyetherimide base film, is a thermal control film material for spacecraft. Results indicate a mass increase: atomic oxygen does not erode F-OSR in low earth orbit. Thermo-optical properties show no marked change. In fact, F-OSR is verified as retaining its initial properties after exposure on ISS orbit for 46 months. Transmission electron microscopy (TEM) observation of cross-sections, including those of the exposed surface, showed that a new layer had formed over the flight sample. Qualitative analysis of the new layer indicates that the layer mainly comprises silicon and oxygen. The layer is chemically produced by deposited silicon contamination and atomic oxygen, which would be SiO2. This experiment also provides actual quantitative contamination data on ISS, contributing to improvement of contamination control on ISS in the future., Physical characteristics: Original contains color illustrations, 資料番号: AA0064307018, レポート番号: JAXA-SP-08-015E}, pages = {149--154}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Evaluation of F-OSR exposed to space on SM/SEED experiment}, volume = {JAXA-SP-08-015E}, year = {2009} }
