LDPE Partial Discharge Properties with Plasma-Treated Boron Nitride
This paper investigates the partial discharge (PD) characteristics of the low-density polyethylene (LDPE) composite materials with plasma treated boron nitride (BN) nanoparticles. With BN, surface derivatization of BN through plasma treatment in the LDPE matrix makes nanoparticles disperse more efficiently and inter-nano compatibility. Improved interfacial bonding due to higher trapping properties and reduced charge mobility suppresses activity of PDs to a large extent. In comparison with untreated BN composites, experimental studies show great enhancement in dielectric characteristics such as PD inception voltage and discharge value. These findings indicate that plasma-treated BN can be promising to serve as a nanofiller in the insulation of polymer high-voltage designs to improve its reliability.
