硅氧烷原子氧防護(hù)膜工藝及防護(hù)性能研究

The preparation of organic silicon atomic-oxygen -protection film and its properties

摘要: 原子氧是對低地球軌道航天器構(gòu)成重要影響的空間環(huán)境因素之一，嚴(yán)重影響著航天器在軌的安全運(yùn)行。文章重點介紹了制備工藝對六甲基二硅氧烷原子氧防護(hù)膜結(jié)構(gòu)及性能的影響，分析了防護(hù)膜的聚合原理，并對其結(jié)構(gòu)、成分進(jìn)行了測試分析，從而獲得了防護(hù)膜的工藝參數(shù)。最后對防護(hù)膜進(jìn)行了原子氧輻照實驗與測試，結(jié)果表明采用等離子體聚合方法制備的原子氧防護(hù)膜具有很好的耐原子氧性能。

Abstract: 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.
