Beschreibung
Zusammenfassung:	In this patent, we proposed a method for preparing a composite absorbent material based on magnetic nanoparticles/graphene/carbon fibers. It is worth mentioning that in this method, graphene grows uniformly on the surface of carbon fiber, and then magnetic nanoparticles are introduced in between the gaps of graphene to form a magnetic loss layer, so that the composite material has both dielectric loss and magnetic loss, which is conducive to achieve impedance matching by adjusting the electromagnetic parameters of the material. The prepared absorbing material is a multi dimensional, cross-scale composite material constructed from zero-dimensional, one dimensional and two-dimensional materials, which can adapt to the multi-dimensional absorption characteristics of electromagnetic waves.
