This paper investigates the effects of high magnetic field on electrical treeing of silicone rubber (SiR). Experimental results show that electrical trees are more easily to be initiated and spread further along the direction of electric field under the effects of high magnetic field. When the direction of high magnetic field is perpendicular to that of electric field, magnetic field with higher magnetic flux density also results in larger accumulated damage area. Splitting of energy band structure and changes in polarization characteristics result in a lower interface barrier and more serious partial discharge, thus causing the weakened resistance to electrical treeing in high magnetic field. Based on the insulation degradation mechanism, SiR was modified by adding ferroferric oxide (Fe 3 O 4 ) nanoparticles to improve its insulation performance in high magnetic field. Moderate addition amount of Fe 3 O 4 nanoparticles is proved to be able to suppress electrical treeing in high magnetic field by forming quantum dots, modifying polarization properties and partial discharge behavior. Excessive addition of Fe 3 O 4 nanoparticles has negative effects on suppressing electrical treeing due to the magnetization of the nanocomposites.INDEX TERMS Magnetic field, electrical tree, nanocomposites, quantum dot.

“…38,39 For example, numerous research has discovered emergent Fe 3 O 4 /PDMS to be a magnetic-dielectric composite with potential for improving antenna bandwidth properties in addition to adjustable dielectric qualities, minimizing magnetic loss under a magnetic field. 40 In this regard, to the best of our knowledge polymer grafting ceramic composites have manifested more advantages over ceramic bulk, for instance, composites provide good low energyconsumption, are easier to mould, with good integration during circuit manufacturing processes. 41 Nanoparticle structures consist of an internal particle (core) or multicore, and a coating forming a shell.…”

In this study, 3D biopolymeric materials based on the blends of collagen (Coll), chitosan (CTS), and hyaluronic acid (HA) were prepared by lyophilization technique. Magnetic particles synthesized by precipitation of iron (II) sulfate heptahydrate and iron (III) chloride hexahydrate in an aqueous solution of chitosan were added to a biopolymer mixture. Dialdehyde starch (DAS) was used as a cross‐linking agent for the materials. The structure of the obtained materials was studied using infrared spectroscopy and scanning electron microscope imaging. The properties of the 3D materials such as density, porosity, swelling ability and mechanical properties were studied. It was found that 3D composites made from collagen, chitosan, and hyaluronic acid with magnetic particles are hydrophilic with a high swelling ability (up to 2,646%). Cross‐linking of such biopolymeric materials with DAS alters the swelling degree and porosity of materials. The cross‐linking process has no significant effect on the density of the materials. The addition of magnetic particles to Coll/CTS/HA materials decreases its swelling ability (1,795% for material containing 30% of magnetic particles) and increases the density of the studied materials. 3D materials based on Coll/CTS/HA with magnetic particles are rigid and inflexible. With the increasing content of magnetic particles in the polymer blend, the Young's modulus decreases. 3D material with magnetite particles can be used in biomedical applications, such as tissue repair and drug delivery.
