Abstract

The invention relates to an MXene/Ni composite material as well as a preparation method and application thereof. The MXene/Ni composite material comprises an MXene carrier and nickel balls compoundedon the MXene carrier, wherein the nickel balls are distributed on the surface and between layers of the MXene carrier, the particle sizes of the nickel balls are not larger than 1 micron, and the MXene carrier is Ti<3>C<2>T<x>. According to the MXene/Ni composite material provided by the invention, the nickel balls are uniformly loaded on the surface and between layers of the MXene material, so the agglomeration phenomenon of particles is improved, the specific surface area of the material is increased, an interface between the materials is increased, wave-absorbing capacity at low frequency bands from 2 GHz to 18 GHz is enhanced, the maximum absorption (reflectivity) of electromagnetic waves reaches -47.06 dB, and excellent wave-absorbing capacity is shown.

Description

technical field [0001] The invention belongs to two-dimensional metal carbide or nitride material (Mxene), in particular to an MXene / Ni composite material and its preparation method and application. Background technique [0002] Electromagnetic waves have been widely used in the fields of radar, advanced detectors, and precision weapons, which have also caused thorny problems such as electromagnetic pollution, electromagnetic interference, and leaks. The development of high-efficiency absorbing materials is of great significance to protect the environment and human health, and ensure information security. [0003] Magnetic metal Ni has high magnetic permeability at GHz frequency, magnetic metal Ni is easy to prepare, cheap, and its oxidation resistance is better than other magnetic metals (such as Fe, Co), therefore, magnetic metal Ni is widely used Applied to the field of electromagnetic absorption. Two-dimensional metal carbide or nitride material (Mxene), as a two-dimen...
