Biomass fly ash as nanofiller to improve the dielectric properties of low-density polyethylene for possible high-voltage applications

“…The dielectric constant of PE with various nanofillers, such as alumina (Al 2 O 3 ), silica (SiO 2 ) [ 17 ], iron oxide (Fe 2 O 3 ) [ 18 ], titania (TiO 2 ) [ 19 ], zirconia (ZrO) [ 20 ] and magnesia (MgO) [ 21 ], have been the subject of numerous experimental studies up to this point. These studies have reported improved dielectric constant, subsequently enhancing the breakdown strength of the material in high voltage applications [ 22 , 23 ].…”
