abstract = "Nano-sized Al 2O 3/polyimide composite films based on Pyromellitic dianhydride(PMDA) and 4,4′-Oxydianiline(ODA) were synthesized by addition with different contents of nano-sized Al 2O 3 via in situ polymerization. Before addition, nano-Al 2O 3 particles were firstly modified by coupling agent DB550. The morphology, structure and properties including the mechanical and electrical properties were investigated. SEM microstructures analysis result indicated that the inorganic particles were homogenously dispersed in the polyimide matrix by means of the ultrasonic-mechanical method and the treatment of coupling agent DB550. XRD analysis showed that the addition of nano Al 2O 3 particles destroyed the molecular order of the PI matrix. Moreover, with the increased in Al 2O 3 content, the weaken effect on the molecular order also increased. The mechanical property decreased with the increase of Al 2O 3 content. Better electric breakdown strength could be achieved if the pure polyimide films were incorporated with nano-Al 2O 3 particles.",
