“…They observed that the treatment of organoclay resulted in higher value of resistivity, dielectric strength, and thermal stability compared to untreated nanocomposites. Chen et al have reported the influence of four different types of stabilizers namely m‐aminophenylboric acid, 2‐methoxy‐5‐pyridineboric acid, m‐aminobenzoic acid and 4‐dimethylaminobenzoic acid on the insulating properties of LDPE/HDPE blend 17 . The blends were prepared by solution mixing process by adding 1 wt% of stabilizers into the blend of LDPE and HDPE (90/10 ratio).…”

The current research aims to study the influence of loading of aluminum oxide (Al2O3) and titanium dioxide (TiO2) nanoparticles on the mechanical, electrical, dielectric, thermal and dielectric breakdown strength properties of high density polyethylene (HDPE) specially used for the main insulation in power cables. The HDPE/Al2O3 and HDPE/TiO2 nanocomposites were prepared by melt blending technique with different ratios of nanoparticles. A modifier was used to reduce the agglomeration of TiO2 and Al2O3 nanoparticles inside the HDPE matrix. There are improvement in tensile strength (35% and 47.2%), tensile modulus (37.9% and 40.8%), flexural strength (18.8% and 23.1%), flexural modulus (11.2% and 12.4%), impact strength (11.8% and 13.9%), electrical conductivity (102 and 104), dielectric constant (80% and 224%), dielectric breakdown strength (35% and 41%), thermal stability (43°C and 34°C), melting point (5.5°C and 5.9°C), hardness (7.3% and 9.4%), and crystallization temperature (3.3°C and 4.2°C) of HDPE/Al2O3 and HDPE/TiO2 nanocomposites, respectively, after certain loading of both fillers compared to neat HDPE. The elongation at break and crystallinity were reduced after the addition of both nanofillers within the HDPE matrix. Except thermal stability, the titania based nanocomposites exhibited good performance compared to alumina based nanocomposites. Overall, this substantial improvement in results showed that both composites can be used for high voltage cable application.

“…The trapping sites introduced by the inorganic fillers may be conducive to reduce the conductivity of XLPE under high electric field and thus control the loss and heat production. In addition, strong trapping effects may also constrain the flexibility of charges, giving rise to more space charge accumulations [25].…”

Here, based on the dielectric response analysis, we report the charge transport dynamics as related to space charge accumulation for three model XLPE composites with 2D platelet silicate fillers. Dynamics of charge transport and the interplay between polarization and space charge are revealed by the equivalent circuit analysis with the Dissado-Hill dielectric response model. In addition to the quasi-DC process, a characteristic dielectric loss peak in the frequency range of 0.1 Hz to the power frequency is observed and attributed to the relaxation of charges trapped by fillerpolymer interfaces. It is demonstrated that the physical nature of trapping and transport revealed by parameters extracted from the quasi-DC process and dielectric loss peak can be well correlated to the characteristics of space charge accumulations in the model XLPE composites containing distinctively different 2D platelet fillers.

“…There is an excellent ability for m -ABA to capture high-energy electrons in polymers. 33 Improving the compatibility of m -ABA with CE and the agglomeration of nano-SiO 2 may be achieved by grafting m -ABA onto nano-SiO 2 particles. This synergy makes the breakdown voltage of CE-based nanocomposites a noteworthy improvement ( Figure 1 d).…”

Voltage-Stabilizer-Grafted SiO₂ Increases the Breakdown Voltage of the Cycloaliphatic Epoxy Resin

Cycloaliphatic epoxy (CE) resin plays a vital role in insulation equipment due to its excellent insulation and processability. However, the insufficient ability of CE to confine electrons under high voltage often leads to an electric breakdown, which limits its wide applications in high-voltage insulation equipment. In this work, the interface effect of inorganic nano-SiO 2 introduces deep traps to capture electrons, which is synergistic with the inherent ability of the voltage stabilizer m -aminobenzoic acid ( m -ABA) to capture high-energy electrons through collision. Therefore, the insulation failure rate is reduced owing to doping of the functionalized nanoparticles of the m -ABA-grafted nano-SiO 2 ( m -ABA-SiO 2 ) into the CE. It is worth noting that the breakdown field strength of this m -ABA-SiO 2 /CE reaches 53 kV/mm, which is 40.8% higher than that of pure CE. In addition, the tensile strength and volume resistivity of m -ABA-SiO 2 /CE are increased by 29.1 and 140%, respectively. Meanwhile, the glass transition temperature was increased by about 25 °C and reached 213 °C. This work proves that the comprehensive performance of CE-based nanocomposites is effectively improved by m -ABA-SiO 2 nanoparticles, showing great application potential in high-voltage insulated power equipment.
