核壳结构LaOCl/LaFeO3纳米纤维的阻抗匹配设计及 其电磁吸波性能研究

The widespread applications of electromagnetic (EM) waves in wireless communication and detection may lead to severe EM wave pollution, which drives the urgent need for absorbents. However, satisfactory impedance matching remains a challenge wide bandwidth absorption one-dimensional core-shell absorbers. To cope with this challenge, study, novel LaOCl/LaFeO3 nanofiber (NF) is designed successfully synthesized via electrospinning followed by proper thermal treatment. This unique structure first assembles conductive magnetic LaFeO3 shells ionic compound LaOCl cores. Benefiting from synergistic contributions dielectric loss coupling matching, NFs exhibit dramatically optimized performance minimum reflection (RL) −40.1 dB (at 2.0 mm) an effective (EAB) 6.4 GHz 2.4 under ultra-low filler loading 4 wt%. work provides promising NF absorber opens up new avenue tune match composition microstructure design.
