Synthesis and atomic oxygen resistance of phosphorus-containing polyimide

  • 摘要: 利用自行合成的含磷芳香族二胺单体——二(3-氨基苯基)苯基氧化磷(DAPPO),制备了一系列含磷聚酰亚胺薄膜.在原子氧地面模拟设备中对该薄膜进行了原子氧暴露实验,并采用场发射扫描电子显微镜(FE-SEM)和X射线光电子能谱(XPS)等分析手段对原子氧暴露前后薄膜表面的聚集态结构和化学结构演化进行了分析.结果表明,原子氧暴露后,引入含磷二胺单体的聚酰亚胺薄膜表面形成了富磷保护层,剥蚀率减小,抗原子氧性能明显提高, 磷质量分数为5.47%的聚酰亚胺薄膜在原子氧作用20h的总剥蚀率分别降低为Kapton和Upliex-R型聚酰亚胺的13%和20%.
