| 摘 要： | 采用反向沉淀法制备了Mg（OH）2-ZnO纳米粒子，通过原位聚合和热亚胺化的方法成功制备了不同纳米Mg（OH）2-ZnO粒子质量分数的纳米Mg（OH）2-ZnO/聚酰亚胺（PI）复合薄膜，通过SEM、热重分析、介电谱测试仪和击穿场强测试仪对薄膜的表面形貌、热稳定性、介电性能和击穿强度进行表征和测试。结果表明：Mg（OH）2-ZnO纳米粒子均匀地分散在PI基体中，Mg（OH）2-ZnO/PI热稳定性下降，介电常数、介电损耗和电导率增加，击穿场强随纳米粒子增加先增加后减小，在纳米粒子含量为2%时，达到最大值296 kV/mm。

| Abstract: | Nano Mg(OH)2-Zn(OH)2 particles were prepared by reverse precipitation method, nano Mg(OH)2-ZnO/polyimide(PI) composite films with different mass contents of Mg(OH)2-ZnO were successfully prepared by in-situ polymerization and thermal imidization. The surface morphology, thermal stability, dielectric properties and breakdown strength of the films were characterized by SEM, TG, dielectric spectrum tester and breakdown strength tester. The results show that the Mg(OH)2-ZnO nanoparticles are homogeneously dispersed in the PI matrix, thermal stability decreases, dielectric constant, dielectric loss and electrical conductivity have been increased, the breakdown strength of nano Mg(OH)2-ZnO/PI composite films increases first and then decreases with the increasing of nanoparticles, and reaches a maximum value of 296 kV/mm at nanoparticle content of 2%. |
