摘要
针对镍金属网在电磁屏蔽中的低吸收效能(SEA)和较高反射(SER)问题,通过电沉积方法在镍金属网(NM)表面负载镍铁双氢氧化物(NiFe LDH)纳米片,旨在提升材料的以吸收为主的屏蔽性能.处理后材料的微观结构和电磁特性得到显著改善,尤其是在X波段内实现了优异的56dB的SEA和2dB的SER.同时,NiFe LDH纳米片优化了介电常数、磁导率、衰减常数和阻抗匹配,证明其在电磁屏蔽领域的广泛应用前景,合成简单且成本效益高.
Abstract
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.
