| 摘 要： | 文章模拟真空紫外辐照条件,研究波长5~200 nm的真空紫外线(VUV)对环氧树脂648以及环氧基纳米复合材料的辐照损伤效应.质量损失、扫描电子显微镜、质谱仪和X射线光电子谱仪分析结果表明:纳米TiO2起到明显抗真空紫外辐照的作用.辐照后,与环氧树脂相比,环氧基纳米复合材料的质量损失大幅度降低,弯曲强度变化较小,出气量和出气成分减少,表面没有新的C峰出现,表面O 1s峰的主要成分没有发生变化. |

| Abstract: | Irradiation damage effects of the epoxy resin 648 and epoxy nano-composites are studied in a simulated vacuum ultraviolet irradiation(VUV) condition with wavelength ranging from 5 nm to 200 nm.Experimental results of the mass loss,SEM and XPS show that nano-TiO2 particles lead to better resistance performance under the VUV.As compared with epoxy resin,the epoxy nano-composite shows significantly less mass loss,smaller flexural strength variation and a decrease of gas extraction with less gas component varie... |
| Keywords: | vacuum ultraviolet irradiation epoxy resin nano-composites irradiation damage |
