Abstract: Low-density polyethylene (LDPE) is one of the most comprehensive products used as insulation materials in power equipment. How to improve its dielectric properties by doping inorganic particles in LDPE has always been the focus of many researchers. In this paper, silica (SiO2) particles and montmorillonite (MMT) particles were added to LDPE, the order of adding particles was changed, and different micro-nano composites was made. The crystallization characteristics of composites were analyzed, the curves of the… Show more

“…By mixing and ultrasonic treatment of the twin-screw extruder, nano-SiO 2 particles can obtain better uniform dispersion [33,34], which are easy to form more interface domains. In the previous study [21], it was proved that the addition of SiO 2 particles will introduce deep traps into the matrix LDPE. Under the action of the electric field, the charge cannot be trapped and is limited on the surface of dielectric materials.…”

“…Figure 2 shows the crystalline morphology of each material under PLM after being etched by concentrated sulfuric acid mixed with potassium permanganate. As both the previous writing and the ICHVE 2020 conference were held during the COVID-19 epidemic period, universities were closed, so the crystal cell size of each material was not marked in time [21,22]. Now, the epidemic situation in China is well controlled and universities have been opened.…”

“…The introduction of a hybrid nanofiller can achieve a robust interfacial bonding compared to a single filler system that is attributed to synergistic effect [ 5 ], and this process enhanced the mechanical behaviour of the XLPE nanocomposites [ 6 ] in addition to dielectric and thermal properties [ 7 ]. The properties of hybrid nanocomposite improved in dielectric properties and thermal conductivity in addition to promoting mechanical properties on Young’s modulus and tensile strength [ 3 , 8 , 9 , 10 ] and showed remarkable performance with a homogeneous distribution of hybrid nanofiller obtained at low nanofiller loading with a maximum of 1 wt.% [ 11 , 12 , 13 ]. These successful studies proved that a combination of two different background characteristics achieve synergistic effect towards the nanocomposite with high compatibility achieved between matrix–nanofiller and interfiller.…”
