Abstract: This paper focuses on the effect of nanoparticle surface modification on the charge transport characteristics in XLPE/SiO 2 nanocomposites. A titanate coupling agent (TC9) and a 3-(Methacryloyloxy)propyltrimethoxysilane (KH570) were used for the surface modification of SiO 2 nanoparticles. It was found that both KH570 and TC9 coupling agents improve the nanoparticle dispersion compared with unmodified SiO 2 nanoparticles. The improvement in dispersion was found to be due to increased surface hydrophobicity of … Show more

“…Since T. J. Lewis [11] first proposed the concept of nanodielectrics in 1994, polyethylene-based nanocomposites have developed from LDPE nanocomposites to XLPE nanocomposites. It has been demonstrated that XLPE nanocomposites can improve electrical properties [12][13][14][15][16][17]. The interface in nanocomposites between the polymer matrix and nanoparticles is the main reason for the improvement in the electrical properties [18][19][20][21][22][23][24].…”

“…Until recently, most studies have been limited to the insulation nano-doped polyethylene, which has been attracting more and more attention. It has been reported that polyethylene-doped inorganic nanoparticles such as MgO, ZnO and SiO 2 can significantly suppress the accumulation of space charge in the insulation [21][22][23][24][25]. Some researchers add SrFe 16 O 19 to the semiconductive layer to reduce the injection of space charge in the insulating layer by using the Lorentz force of magnetic particles on the charge [26].…”

“…Meanwhile, charges would be injected from the electrode into the material. The charges originating from above sources can be trapped and then space charge accumulation takes place [23]. Since the positive ion is heavier than the electron, the mobility of the positive ion is much lower than that of the electron with the same electricity under the same applied electric field.…”
