摘要
研究防静电Kapton二次表面镜(ITO/Kapton/Al)、S781白漆两种典型热控涂层,在不同能量电子辐照后太阳吸收比退化情况,并利用X射线光电子能谱和扫描电子显微镜对样品表面的成分和形貌进行了分析。结果表明:相同电子注量下,不同能量电子对样品的太阳吸收比退化作用程度是有区别的。而样品光谱反射率、表面形貌、表面成分的损伤效应类似,说明不同能量电子辐照下,样品的退化机理是一致的。
The ITO/Kapton/Al Films and the S781 white coatings were two typical thermal control coatings used on spacecrafts.The effects of electron irradiations of different energy on the solar absorptance（αs） of them were stud-ied.The X-ray photoelectron spectra（XPS） and the scanning electronic microscope（SEM） were used to analyze the element contents and the morphologies of the samples.The results show that for the same irradiation flux,the αs of thermal control coatings are degraded to different degree after different energy electron irradiation.The changes of the reflection spectrums,the morphologies and the atomic contents of the samples are similar due to the same mechanism after electron irradiation of different energy.
