Effects of water on the dielectric response of calcined silica-based polyethylene nanocomposites

Polymer nanocomposites have become one of the vital research areas in exploring the prospective use of new dielectric materials. Thus far, there have been many positive dielectric results reported, especially for the use of polyethylene nanocomposites as electrical insulation. However, degraded diel...

Thus far, there have been many positive dielectric results reported, especially for the use of polyethylene nanocomposites as electrical insulation. However, degraded dielectric performances of the materials have also been reported and, in some cases, these have been associated with the presence of water within the materials. In this paper, the effects of water absorption on the dielectric response of polyethylene (PE) nanocomposites containing uncalcined and calcined silicon dioxide (SiO2) nanofillers are reported. The results show that immersing PE/SiO2 nanocomposites under different water immersion periods changes the dielectric response of the materials.
