摘要
在模拟空间环境原子氧辐照的条件下,采用固定的原子氧束流密度进行不同时间的辐照试验,研究了温控材料TeflonFEP/Al薄膜的质量损失、光学性能、表面形貌和表面粗糙度的演化规律.结果表明,材料的质量损失与原子氧的作用时间成正比.辐照前后材料的表面形貌和表面粗糙度发生明显变化,致使太阳吸收率发生明显变化,从而导致材料的光学性能发生变化.
In order to simulate the atomic oxygen effects in space environment on thermal control materials, the changes in mass loss, optical properties, surface morphology and surface roughness of Teflon FEP/Al films were investigated in the conditions of a fixed flux of atomic oxygen beam for different irradiation time. The results showed that the mass loss is in proportion to the irradiation time of atomic oxygen. The surface roughness and morphology of irradiated samples significantly changed before and after AO exposure. The changes resulted in increasing the solar absorptance of irradiated samples and changing optical properties of test materials.
