摘要
通过二步法制备聚酰亚胺薄膜复合材料,研究不同填充浓度及击穿测试环境对聚酰亚胺电气强度的影响。结果表明:绝缘油击穿测试环境能明显的提升聚酰亚胺薄膜击穿场强,在测试环境为直流-绝缘油时,聚酰亚胺薄膜的击穿场强最高。与此同时,绝缘油击穿测试环境能明显的提高不同填充浓度的PI-PMMA复合薄膜的击穿场强,填充浓度为3%及10%的PI-PMMA复合薄膜,均在直流-绝缘油测试环境下击穿场强最高。不超过3%的浓度改性PI复合薄膜的击穿场强效果最佳。
Polyimide film composite is prepared by a two-step method.The effects of different filling concentrations and breakdown test environments on the electrical strength of polyimide is studied.The results show that the breakdown test environment of insulating oil can significantly increase the breakdown field strength of the polyimide film.When the test environment is DC-insulating oil,the breakdown field strength of polyimide film is the highest.At the same time,the breakdown test environment of insulating oil can significantly improve the breakdown field strength of PI-PMMA composite films with different filling concentrations.The PI-PMMA composite film with filling concentration of 3% and 10% has the highest breakdown field strength in DC-insulating oil test environment.The breakdown field strength of the modified PI composite films with a concentration less than 3% is the best.
