| 中文摘要: |
| 目的自行合成聚酰亚胺,并用其对环氧树脂进行共混改性,探索改性的方法。方法以4,4'-氧双邻苯二甲酸(4,4'-Oxydiphthalic anhydride, ODPA)、4,4'-二氨基二苯醚(4,4'-Oxydianiline, ODA)、对苯二胺(p-Phenylenediamine, PPD)、降冰片烯二酸酐(5-Norbornene-2,3-dicarboxylic Anhydride, NA)为原料,进行聚酰亚胺的合成,利用傅立叶变换红外光谱分析,对其化学结构进行表征。将合成得到的聚酰亚胺与E-51环氧树脂共混,得到改性环氧树脂。结果合成的聚合物被确认为聚酰亚胺。合成所得低分子量聚酰亚胺可溶于环氧树脂,聚合后得到均一、透明的共混产物。结论成功合成低分子量的聚酰亚胺以及聚酰亚胺改性的环氧树脂。 |

| Objective In this study, epoxy (E51) was modified with self-made polyimide to investigate an effective way to strengthen epoxy. Methods 4,4'-Oxydiphthalic anhydride (ODPA), 4,4'-Oxydianiline (ODA), p-Phenylenediamine (PPD) and 5-Norbornene-2,3-dicarboxylic Anhydride (NA) was used to synthesize Polymerization of Monomer Reactants (PMR) type polyimide, and the product was characterized by Fourier transform infrared. Then the polyimide was blended with epoxy. Results The self-made polyimide was completely imidization and could be dissolved in epoxy, and the mixture could be cured to get an even and translucent product. Conclusion In this experiment, the low molecular weight polyimide was synthesized successfully, and it could be blended with epoxy to get a modified product. |
