Partial Discharge Characteristics of Low Density Polyethylene Nanocomposites Containing Plasma Treated Boron Nitride Nanofillers

摘要

This paper reports the investigation of partial discharge (PD) characteristics of the plasma treated Boron Nitride (BN) nanoparticles by using atmospheric pressure plasma (APP) discharge in order to enhance the interaction between the nanofiller with the low density polyethylene (LDPE) matrices. With different loading levels of BN nanofiller (1, 3 and 5 wt%) was added into the LDPE, the phase resolved PD behavior of the untreated and plasma treated BN/LDPE nanocompoistes were measured based on IEC 60270 standard. Fourier Transform Infrared (FTIR) Spectroscopy analysis was used to characterize the chemical structures of nanoparticles and nanocomposites sample. The results showed that the inclusion of plasma treated BN could improve the PD resistant properties of the nanocomposites compared to the untreated BN/LDPE nanocomposites due to the increased of the hydroxyl groups after the plasma treatment.
