摘要

摘要: 在激光源原子氧地面模拟设备中对Kapton/Al薄膜二次表面镜进行了原子氧与紫外综合辐照实验，研究了Kapton/Al薄膜质量及太阳吸收比的变化，重点关注了实验前后Kapton/Al薄膜表面结构及成份的改变。结果表明：Kapton/Al薄膜二次表面镜的质量随辐照时间的增加逐渐减小，太阳吸收比的变化趋势与之相反，随辐照时间的增加逐渐增大；综合辐照后Kapton/Al薄膜表面主要官能团数量呈下降趋势；综合辐照过程中材料表面C-C键、C-N键的破坏及在原子氧和紫外环境中重新结合成新的化学结构是造成Kapton/Al薄膜性能退化的主要微观机制，气体小分子的挥发是造成Kapton/Al薄膜质量损失的主要原因。

Abstract: Atomic oxygen (AO), near ultraviolet (NUV) and vacuum ultraviolet (VUV) irradiation test of Kapton/Al second surface mirror film was conducted using laser-induced AO simulation facility; the mass, solar absorptance, surface structure and composition were investigated. The results indicate that the mass of Kapton/Al film is decreased with increasing irradiation time, but the solar absorptance displays entirely different trend, which is increased with increasing irradiation time. After irradiation, the quantity of the main functional groups in Kapton/Al film surface presents downtrend basically. The breakage of C-C and C-N bonds and new chemical bond creation in Kapton/Al film surface are considered mechanisms of the degradation, and gas molecule volatilization leads to the mass loss of Kapton/Al film.
