The construction of Dupont corona-resistant polyimide film was analyzed by means of SEM and AFM, and the surface morphology of the original film and the corona- resistant film were compared with each other after aged.

• 本文借助扫描电镜和原子力显微镜分析了Dupont耐电晕聚酰亚胺薄膜的结构,比较了电晕老化后原始和耐电晕聚酰亚胺薄膜的表面形貌,得出Dupont耐电晕聚酰亚胺薄膜是三层结构,上下两个表层中含有较多的Al-无机化合物,是无机-有机复合结构。
