Polyimide film, as a special type of engineering plastic film, is a kind of basic insulating material and is widely applied in the aerial, nuclear, microelectronic industry, turn to turn insulation and turn to ground insulation of inverter-fed motors. However, with the disadvantage of organic polymer, its corona-resistance property is not good enough, which makes insulation early failures occur frequently...
With advantage of excellent thermostability, mechanical property, polyimide films have been widely used in the aerial, nuclear, microelectronic industry. However, The dielectric breakdown of the polyimide films caused by surface charge often occurs and becomes one of main problems to the safety and reliability of insulation system. Addition of nanoparticles into polyimide films can improve the insulating...
Polyimide film, as a special type of engineering plastic film, is a basic insulating material and is widely applied in the electrical and electronic industry. Addition of nanoparticles into polyimide can improve the insulating properties compared with undoped material. However, due to the change of the material structure, the trap characteristics and charge behavior are altered as a consequence. The...
