摘　　要：采用热液法制备了一系列不同Zr和Al比例的纳米粒子分散液,用原位聚合法分别制备了无机纳米杂化聚酰亚胺薄膜,并进行了SEM分析、电气强度和耐电晕测试。结果表明:Zr和Al的掺杂比例对杂化薄膜的耐电晕寿命及击穿场强影响较大,其耐电晕寿命最大可达Kapton100CR薄膜的4倍。A series of nano-dispersions with different ratio of Zr and Al was prepared by hydrothermal method,and the corresponding inorganic nano-hybrid polyimide films were prepared through in-situ polymerization method.The hybrid film was characterized by SEM,electric strength and corona-resistant test.The results show that the doping ratio of Al and Zr has great effects on the corona-resistant life and breakdown strength of the hybrid film,and the maximum corona-resistant life is 4 times of that of Kapton 100 CR film.
