Double hydroxide modified nickel metal mesh with enhanced electromagnetic shielding performance
To address low absorption(SEA)and high reflection(SER)issues in the nickel metal meshes for electromagnetic shielding,the electro-deposition was used to load nickel iron hydroxide(NiFe LDH)nanosheets onto the nickel mesh in order to enhance the absorption-dominant shielding performance of the material.The microstructure and electromagnetic properties of the material were notably enhanced,especially achieving a SEA of 56 dB and SER of 2 dB in the X-band.Furthermore,the dielectric constant,magnetic permeability,attenuation constant,and impedance matching were improved with the NiFe LDH nanosheets.This demonstrates their wide application potential in electromagnetic shielding with simplicity in synthesis and cost-effectiveness.
