Although the rapid development of electronic information technology has made our lives more convenient

they have also caused increasingly serious electromagnetic radiation pollution. In order to completely eliminate electromagnetic radiation pollution

electromagnetic shielding materials with low reflectivity and high absorption rates are increasingly being favored by researchers. For the above reasons

this paper analyzes the design concept of polymer-based electromagnetic shielding materials doped with magnetic fillers based on the electromagnetic shielding mechanism. And it also summarizes the preparation of magnetic metal/polymer shielding materials

magnetic filler/metal/polymer shielding materials

magnetic filler/MXene/polymer shielding materials

magnetic filler/carbon/polymer shielding materials and magnetic materials/conductive polymer shielding materials

respectively. The intrinsic link between material structure and shielding effectiveness and reflection loss is discussed in detail. In conclusion

the key challenges

potential applications and prospects for the development of such materials are presented.
