实验研究了注量在1．0×1011-1．0×1016p／cm2范围依次变化时110keV质子辐照引起的温控涂层热光性能的变化,并使用XPS谱仪分析了辐照样品化学态的变化．实验结果表明,质子注量不高于 1．0×1014p／cm2时,同种材料的温控涂层样品的相对光反射率变化很小,同时同种材料样品的表面化学结构如化学位移和元素的比例变化很小．当注量高于1．0×1014p／cm2时,样品的相对光反射率变化明显,样品表面的原子化学结构变化大,化学位移明显增加,元素比例变化显著,所有样品表面的C元素比例明显增大而O元素比例明显减小．一定注量的低能质子辐照能够使某些低太阳吸收率αs的温控涂层的太阳吸收率变得更低,具有改善热光性能的效果．质子辐照之后温控涂层样品表面化学结构的变化与样品的物理性能的变化存在直接的关联．
The change of thermo-optic properties of temperature-controlled coatings caused by 110 keV proton irradiation when the fluency was varied in the range of 1.0 × 10 11-1.0 × 10 16 p / cm 2 was studied experimentally. The chemical composition of the irradiated samples was analyzed by XPS. Change of state The experimental results show that when the proton fluence is no higher than 1.0 × 1014p / cm2, the relative optical reflectance of the samples with the same material is very small, and the chemical structures of the samples of the same material such as chemical shift and The proportion of elements changes very little. When the fluence is higher than 1.0 × 1014p / cm2, the relative optical reflectance of the sample changes obviously. The atomic chemical structure of the sample changes greatly, the chemical shift obviously increases, the proportion of the element changes significantly, and the proportion of the C element on the surface of all the samples is obviously Increase the proportion of O elements decreased significantly. A certain fluence of low-energy proton irradiation can make certain solar absorptance of the temperature-controlled coating with low solar absorptance αs lower, which has the effect of improving the thermo-optic performance. There is a direct correlation between the change of the chemical structure of the surface of the temperature-controlled coating sample after proton irradiation and the change of the physical properties of the sample.
