聚酰胺-酰亚胺（PAI）由于其上级热性能和机械性能而在许多应用中被高度期望。本工作以含酰胺的二胺和二酐为原料，通过缩聚和热处理制备了派。制备了派膜和取向的静电纺丝纳米纤维（ANF）。采用FT-IR分析了派在不同退火温度下的结构变化。采用DSC和TGA对派的热性能进行了研究，采用拉伸试验对派膜和ANF的力学性能进行了研究。结果表明，派具有优异的热稳定性和力学性能，在气体分离、高温过滤、增强材料等方面具有广阔的应用前景。
Polyamide-imides (PAIs) are highly desired in many applications because of their superior thermal and mechanical properties. In this work, PAI was prepared from an amide-containing diamine and dianhydride by polycondensation and thermal treatment. Both PAI films and aligned electrospun nanofibers (ANFs) were fabricated. FT-IR was used to determine the structure formation of PAI at different annealing temperatures. DSC and TGA were used to evaluate the thermal properties of PAI, while tensile test was applied to evaluate the mechanical properties of PAI films and ANFs. The results indicated that the PAI possessed both outstanding thermal stability and mechanical properties, which provide opportunities for applications in gas separation, high temperature filtration, reinforcement, etc.
