摘要: Polymer nanocomposites have become one of the vital research areas in exploring prospective use new dielectric materials. Thus far, there been many positive results reported, especially for polyethylene as electrical insulation. However, degraded performances materials also reported and, some cases, these associated with presence water within In this paper, effects absorption on response (PE) containing uncalcined and calcined silicon dioxide (SiO 2 ) nanofillers are reported. The show that immersing PE/SiO under different immersion periods changes Specifically, SiO a noticeable increase real permittivity after immersion. Meanwhile, similar periods, lower compared those equivalent amounts . mechanisms concerning calcination discussed.
