摘　　要：采用Stober法和原位聚合法制备了羰基铁/二氧化硅/聚苯胺(CIP/SiO2/PANI)核壳结构型电磁功能复合材料,并通过X射线衍射(XRD)、扫描电子显微镜(SEM)、红外光谱(FT-IR)以及振动样品磁强计(VSM)表征了复合物的形貌、结构和磁性能。SEM显示,SiO2和PANI先后成功包覆在CIP颗粒表面;XRD和FT-IR进一步证实合成了CIP/SiO2/PANI复合材料;磁测试发现,复合物的饱和磁化强度明显减小。本研究为进一步设计和制备高性能的电磁吸波材料奠定了基础。This paper reported that the CIP/SiO2 / PANI electromagnetic functional composites were prepared by a Stober process and the in situ polymerization. The composites were characterized by means of X-ray diffraction( XRD),scanning electron microscopy( SEM), Fourier transform infrared spectra( FT-IR) and vibrating sample magnetmeter( VSM). SEM photographs showed that CIP particles first were coated with SiO2 shell and then grafted the polyaniline( PANI) shell. XRD and FT-IR further confirmed the formation of CIP / SiO2 / PANI composites. After being coated the PANI shell,the saturation magnetization of CIP / SiO2 / PANI composites decreased obviously. The study lays the foundation for the further design of high-performance electromagnetic wave absorbing materials.
