Właściwości dielektryczne poliestrowej żywicy nasycającej modyfikowanej nanocząstkami przewodzącymi

This paper presents the dielectric properties of the impregnating polyester resin that contains various amount of silver nanoparticles (from 0.2% to 6.1% wt). It was found that at 23°C with lower contents of Ag resistivity increases (Coulomb blockade effect). However, for nanocomposite with 6.1% nanosilver a clear decrease in resistivity, dielectric strength and resistance to partial discharges at 180oC is observed. In turn, introducing a small amount of silica to the resin containing 6.1% wt. Ag causes a marked improvement in dielectric properties.
