摘　　要：介绍真空紫外线的模拟和射流式真空紫外辐射模拟设备(VUV)的工作原理、技术参数及特点,几种航天器用聚合物材料在真空紫外线作用下的损伤结果表明:VUV导致有机基体材料MoS2涂层寿命减小,无机基体材料MoS2涂层寿命增加。VUV对 CF/EP的纤维和基体表面有明显的破损,导致力学性能下降。VUV与温度交变对聚酰亚胺吸光涂层的力学性能有明显影响。VUV引起聚乙烯和橡胶材料不同的附加变形。The simulation of vacuum ultraviolet (VUV) and the working mechanism, technical parameters as well as characters of the gas - jet device for simulating vacuum ultraviolet was introduced. The damage behaviors of some polymers for space application under VUV were initially studied. Results showed that VUV resulted in reducing the life of MoS2 coating with the organic matrix and increasing the life of that with the inorganic matrix. VUV distinctly damaged the surface of the fibber and matrix of PE/EP resulting in decreasing the mechanical properties of the materials. VUV combined with the alternative temperature had a remarkable effect on the mechanical properties of polyimide for absorbing light coatings. The additional deformation induced by VUV in polyethylene and rubber was different.
