Abstract:
"The polyaniline (PANI)-barium ferrite composite with magnetic behavior was synthesized by in situ poly-merization of aniline in the presence of BaFe12O19 nanoparticles of 60-80 nm in diameters. The structure, morphology and magnetic properties of samples were characterized by powder X-ray diffraction, Fourier transform infrared, scanning electron microscopy, transmission electron microscopy and vibrating sample magnetometer technique. The results of spectroanalysis indicated that there was interaction between PANIchains and ferrite particles. The composite exhibited the hysteresis loops of the ferromagnetic nature. The saturated magnetization of composite was 22.2 emu/g and the conductance was 0.069 S/cm."

摘要:
"采用原位掺杂聚合法,将聚苯胺对粒径在60~80 nm的M型钡铁氧体颗粒(BaFe12O19)进行包覆,得到了具有导电性和磁性的复合材料.通过X射线衍射、傅利叶变换红外光谱仪、扫描电镜和透射电镜等测试手段对材料的形貌和结构进行了表征.结果表明:PANI链段与BaFe12O19颗粒之间存在着作用力.使用振动磁强计和四探针法测定了复合材料的磁性能与电性能,其中50%复合材料的饱和磁化强度为22.2 emu/g,电导率为0.069 S/cm."
