摘要: 分别用溶胶-凝胶法和原位氧化聚合法制备了镨掺杂钡铁氧体/聚吡咯复合膜, 借助X射线衍射仪(XRD)、红外光谱(FTIR)、扫描电子显微镜(SEM)、振动样品磁强计(VSM)和矢量网络分析仪等手段表征了复合膜的结构和形貌, 研究了样品的磁性能和吸波性能。结果表明, 复合膜的饱和磁化强度Ms和剩余磁化强度Mr均比钡铁氧体单膜的低, 复合膜的矫顽力Hc比钡铁氧体膜的高; 镨掺杂钡铁氧体--聚吡咯复合膜兼具介电损耗和磁损耗, 有利于拓宽吸收频带和改善吸波性能。

Abstract:Pr-doped Ba ferrite composite film was prepared by a sol-gel method and an in situ polymerization method, respectively. The structure, morphologies, magnetic properties and microwave absorption properties of the samples were characterized using X-ray diffractometer (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscope(SEM), vibrating sample magnetometer (VSM) and magnetic vector network analyzer. The results show that the saturation  agnetization (Ms) and the remanent magnetization (Mr) of the composite film are lower than that of Ba Ferrite film, but the coercivity force (Hc) of the composite film is higher than that of Ba Ferrite film. Pr doped Ba ferrite/ polypyrrole composite film has both dielectric loss and magnetic loss, which is beneficial to widen microwave band and improve microwave absorption properties.
