Abstract

The invention discloses a composite bulk material of resin, ferrite and MXenes. Ferrite molecules are dispersed in a laminated structure of the MXenes to form powder particles, and the powder particles are evenly dispersed in the resin to form the bulk material. On the one hand, the composite bulk material has the advantages of the ferrite material and the advantages of the MXenes, has good conductivity, can still keep certain conductivity when the temperature is lower than 260 K, and meanwhile has good impedance matching performance, and therefore the composite bulk material can be applied as a wave-absorbing material, and is especially suitable for being applied to the low-temperature condition; on the other hand, the resin is introduced into the composite bulk material, the powder particles are evenly dispersed in the resin, the composite bulk material is formed and has the advantage of being easy to form and process, and meanwhile, due to the fact that the curing temperature of the resin is lower than the sintering temperature of the powder particles, the problem that the powder particles are easily oxidized at high temperature is effectively solved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite block material of resin, ferrite and MXenes, its preparation method and application. Background technique [0002] With the rapid development of the electronic information industry, mobile communication devices such as notebook computers, mobile phones, and tablet computers have become popular, covering almost every family, and becoming an indispensable part of daily life. However, with the sharp increase in the use of these wireless communication devices and high-frequency electronic devices, the phenomenon of electromagnetic interference (Electromagnetic interference) and electromagnetic pollution problems are also intensified. [0003] Ferrite material is a double-complex medium, which not only has the ohmic loss, polarization loss, ion and electronic resonance loss of general dielectric materials, but also has the unique domain wall resonance loss, mag...
