| 摘 要： | 电磁波在无线通信等领域的广泛应用导致了严重的电磁污染,迫切需要研发高性能电磁波吸收材料.本文针对吸波材料阻抗不匹配等关键问题,设计并成功制备了新型核壳LaOCl/LaFeO3纳米纤维电磁波吸收剂.这种独特的一维多级结构由导电LaFeO3磁性壳层和离子化合物LaOCl核层组成.基于介电-磁损耗耦合和阻抗匹配的协同作用,LaOCl/LaFeO3纳米纤维在超低负载条件下(4 w t%),表现出-40.1 d B (2.0 mm)的反射损耗和6.4 GHz (2.4 mm)的有效吸收带宽.该工作提出了一种新型LaOCl/LaFeO3纳米纤维吸波材料,并为阻抗匹配调控和电磁吸波性能优化开辟了新策略.
