Nano-additives can improve the physicochemical and electrical properties of insulating oil by enhancing the microscopic interaction. In this article, the microscale interaction characteristics of cage polysilse- squioxane (POSS)-modified insulating oil under nonuniform electric field and nonuniform temperature field and its influence on molecular diffusion are studied. The results indicate that under nonuniform temperature field, the interaction energy between POSS and insulating oil molecules in the high electric field strength area is higher and has better mutual solubility, and the high-temperature area under nonuniform temperature field cannot promote the mutual solubility between POSS molecules and insulating oil molecules. In addition, displacement vector data show that the increase of electric field strength can promote the displacement of insulating oil and POSS molecules, and the molecular displacement at the boundary of nonuniform electric field is higher. The high-temperature region under the nonuniform temperature field can increase the molecular kinetic energy, but the higher viscosity of the insulating oil molecule prevents heat transmission. Furthermore, the mean square displacement (MSD, nonlinear increase) under the nonuniform temperature field is far less than the MSD (linear increase) under the nonuniform electric field strength. This is mainly because the energy of the system under the nonuniform electric field is always at the same level, but the low-temperature area of system under the nonuniform temperature field continuously absorbs energy from the high-temperature area. This article can provide the microscale interaction of Nano-modified vegetable insulating oil under nonuniform electric field and nonuniform temperature field.

Petroleum asphaltenes as well as their derivatives obtained by sulfonation are studied as model fillers in this work. There corresponding particle size (distribution), specific surface area, and elemental composition are described. It is found that the introduction of petroleum components into a polyethylene (PE) matrix improves its electret characteristics (for example, the surface charge density value for PE after 30 days of storage is reduced to $0.07~mu $ C/m2, whereas PE compositions with asphaltenes reached $0.190~mu $ C/m2 and samples with modified asphaltenes $0.382~mu $ C/m2). An increase in the number of sulfonic groups during the modification of asphaltenes leads to the creation of additional charge traps with even higher energies. This, in turn, leads to a significant (almost 2 times) improvement of the PE composites’ electret characteristics. The best electret properties are obtained for a polyethylene composition with 7.5 wt.% sulfonated asphaltenes (SA). The introduction of asphaltenes and SAs increases the thermal stability of the PE electrets by increasing the thermal resistance of the polymer itself. It can be explained by the fact that asphaltenes are more resistant to thermal degradation, and SAs increase the thermal stability of polyethylene even more effectively. The obtained composites can be considered as model systems, as they provide a way to further enhance the thermal stability for polymers electret with traditional fillers by means of particles surface chemical modification.
本研究将石油沥青质及其磺化衍生物作为模型填料进行研究。对其相应的粒度（分布）、比表面积和元素组成进行了描述。研究发现，在聚乙烯（PE）基体中引入石油成分可改善其驻极体特性（例如，储存 30 天后，PE 的表面电荷密度值降至 0.07 美元/平方米，而含有沥青质的 PE 成分达到 0.190 美元/平方米，含有改性沥青质的样品达到 0.382 美元/平方米）。在改性沥青过程中，磺酸基团数量的增加会导致产生能量更高的额外电荷陷阱。这反过来又显著改善了聚乙烯复合材料的驻极体特性（几乎是原来的 2 倍）。含有 7.5 重量百分比磺化沥青质（SA）的聚乙烯成分可获得最佳驻极体特性。沥青质和 SA 的引入通过增加聚合物本身的热阻来提高聚乙烯驻极体的热稳定性。这是因为沥青质更耐热降解，而 SA 能更有效地提高聚乙烯的热稳定性。所获得的复合材料可被视为模型系统，因为它们提供了一种方法，可通过颗粒表面化学改性进一步提高使用传统填料的驻极体聚合物的热稳定性。

Crosslinked polyethylene (XLPE) is a key material for power cables due to its superior performance as electrical insulation. It is co-extruded with a carbon black-filled semiconducting “semicon” polymer layer, which is significantly more conductive than XLPE. Understanding the electrical properties of the XLPE/semicon bilayer and the interface between the layers is critical due to their common use in high-voltage cables, and so, XLPE/semicon bilayers were developed, examined, and compared to XLPE in isolation. These materials were examined using current-voltage and dielectric displacement-voltage [D(P)–E] loop measurements. Current-voltage measurements were meant to examine the changes in leakage current while D(P)–E loops were used to examine the changes in dielectric loss, in both cases due to the addition of the semicon interface. Both techniques were used to analyze the charge transport response and development of space charge polarization in the bulk polymer and across the bilayer interface as a function of polarity at $90~^{circ }$ C. An increase in the apparent conductivity of the XLPE was measured when layered with the semicon, attributed to the increase in charge injection at the XLPE/semicon interface. Additionally, increases in the conductivity were observed with the application of higher electric fields. The addition of the semicon layer resulted in an increase in both the dielectric constant and the dielectric loss, and greater increases in both as the field is increased. Thus, it led to an enhancement in space charge polarization. Based on the experimental measurements from high-voltage D(P)–E loop measurement, a nonlinear circuit model was developed to fit the data and provide a close match to experimental values for resistivity and capacitance. The high-field circuit model was based on forward and reverse biased resistor and diode pathways in parallel with each other and with the bulk damped capacitor, and it predicts space charge limited conduction with a semicon electrode and Poole-Frenkel conduction with a metal electrode, highlighting the importance of interfaces on XLPE insulation performance.
