摘要
原子氧是对低地球轨道航天器构成重要影响的空间环境因素之一,严重影响着航天器在轨的安全运行。文章重点介绍了制备工艺对六甲基二硅氧烷原子氧防护膜结构及性能的影响,分析了防护膜的聚合原理,并对其结构、成分进行了测试分析,从而获得了防护膜的工艺参数。最后对防护膜进行了原子氧辐照实验与测试,结果表明采用等离子体聚合方法制备的原子氧防护膜具有很好的耐原子氧性能。
Materials used on spacecraft's outside surfaces are subjected to many environmental threats of property degradation,among which the atomic oxygen is one of the most important.Organic silicon atomic-oxygen-protection film was prepared by using the method of polymerization.The effects of the preparation processing on the film structure and its durability are discussed,including the principle of the polymerization,the film structure and the composition of the film.The film is tested in our ground based atomic oxygen simulator,and the results indicate that the film enjoys a good performance.
