摘要
以2,4-二氨基-1- [(4′-三氟甲基)苯氨基苯基]苯胺与1,4,5,8-萘甲酸二酐为单体在N,N′-二甲基乙酰胺 (DMAC)中合成了一种新型含氟聚酰亚胺聚合物 (FPI).通过红外光谱和核磁共振对合成的含氟聚酰亚胺进行了结构表征,并对其溶解性、机械性能、光学性能及热稳定性能等进行了测定分析.实验结果表明:FPI溶解性能优异;弹性模量为 7.43 GPa,断裂强度大,具有优良的物理机械性能;热分解温度为 550 ℃,表明该 FPI具有很好的热稳定性.
A new fluorinated polyimide polymer(FPI)is synthesized with 1,4,5,8-naphthalene formic acid dianhydride and N1-(4-(4-(trifluoromethyl)phenoxy)phenyl)benzene-1,2,4-triamine in the N,N′-dimethyl acetamide(DMAC).The structure of the FPI was confirmed by Fourier transform infrared spectroscopy(FTIR),and nuclear magnetic resonance(NMR).Solubility,mechanical properties,optical and thermal properties of the FPI were studied.The results showed that the FPI has excellent solubility,good physical and mechanical properties(well fracture strength with elastic modulus of 7.43 GPa).Thermal decomposition temperature is 550℃,which indicates that the FPI has high thermal stability.
