采用溶液聚合法制备了聚苯胺/聚丙烯酰胺/镍锌铜铁氧体(PANI/PAM/Zn0.4Ni0.5Cu0.1Fe2O4)三元复合物. 利用X射线衍射仪、红外光谱仪、扫描电子显微镜和振动样品磁强计分别表征了样品的结构、形貌和磁性能, 用阻抗/材料分析仪测定了复合物在1 MHz～1 GHz的频率范围内的磁损耗和介电损耗, 并研究了聚苯胺和引发剂的相对含量对复合物的磁损耗和介电损耗的影响. 结果表明复合物中磁性粒子和聚合物之间具有一定的相互作用, 复合物在1 MHz～1 GHz的频率范围内具有较大电磁损耗能力.

The composites of polyaniline/polyacrylamide/Zn0.4Ni0.5Cu0.1Fe2O4 (PANI/PAM/ZNCFO) were prepared via solution polymerization. The structure, component, morphology and magnetic property of the composites were characterized by X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM), respectively. The tangent value of magnetic loss angle and dielectric loss angle of the composites were measured by an impedance/material analyser with the frequecy in the range of 1 MHz～1 GHz. The results revealed that there were some interactions between the magnetic particles and the polymers in the composites, and the composites had good capability of electromagnetic loss in the range of 1 MHz～1 GHz.
