Cyclic Olefin Copolymer Blending
摘要
As shown in the previous analysis, the problem of decreasing breakdown field strength and increasing dielectric loss of polypropylene films at high temperatures is becoming increasingly prominent (Xiao et al. in IEEE Trans. Dielect Elect. Insul. 31:1268–1275, 2024), so it is significant to improve the high-temperature dielectric properties of polypropylene films. Currently, polypropylene modification methods can be divided into two categories: physical modification and chemical modification (Brown in IEEE Trans. Device Mat Reliab. 6:326–333, 2006).
