| 摘 要： | 针对空间环境条件综述了真空紫外线辐射对材料物理、化学等性能的影响及机理。聚合物材料在真空紫外线作用下，表面粗糙度上升，结构发生明显变化，拉伸强度下降。同时透光率、耐热性等均发生变化。真空紫外线与原子氧等其它空间环境因素有一定程度的协同效应。不同材料对各因素的敏感程度稍有差异。

| Abstract: | s The influence of vacuum Ultraviolet(VUV) irradiation on physical and mechanical properties of polymers is reviewed. VUV irradiation can result in increase of surface roughness of polymers,changeable microstructure of their surface, and decrease of tensile strength,as well as deterioration of optical transmisivity and thermal stability.Effects of combination of VUV with other space environment factors such as atom oxygen (AO) are also discussed.Sensitivity to each space environment factor is little different for various polymer materials. |
