Abstract: Two mechanisms have been proposed to explain the suppression of space charge in polyethylene by the addition of nano-fillers, i.e. an interface change that reduces charge injection and a bulk modification that affects charge migration and recombination. The relative importance of each mechanism in Low Density Polyethylene (LDPE) nanocomposites is investigated by the measurement of space charge in samples of doublelayer and triple-layer structures. The experimental results show that the nano-fillers reduce char… Show more

“…The dielectric properties of doped polyethylene are improved by using special effects under nanometer size [ 3 , 4 , 5 ] and interfacial effect between nanoparticles and polyethylene matrix particularly [ 6 ]. Various studies have shown that a small amount of nanodoping can significantly improve the dielectric properties of polyethylene, such as increasing its breakdown field strength, reducing its conductance under high electric field, reducing space charge accumulation and so on [ 7 , 8 , 9 ]. Common nanodopants are nano-inorganic oxides such as nano SiO 2 , Al 2 O 3 , MgO, TiO 2 , ZnO and so on [ 10 , 11 , 12 , 13 , 14 ].…”

“…Space charge distribution is a direct outcome of combined trapping/de-trapping and transport behavior of charges in insulating polymers and varies with trap density, trap depth distribution, and charge carrier mobility [15]. While the space charge phenomena can possibly be controlled by changing the morphology and crystallinity of the polymer, space charge distribution can be influenced by grafting functional groups onto the nanofiller particle surface, influencing charge mobility through the introduction of shallow trap sites [16] or reducing the number of charges trapped in deep traps [1] in the filler/polymer interaction zones.…”
