Synthesis and Properties of Tubular Polyaniline-Barium Ferrite Composite

摘要

The polyaniline-barium ferrite composite was synthesized by in situ polymerization of aniline in the presence of BaFe12O19 nanoparticles. The structure, morphology, and magnetic properties of samples were characterized by powder X-ray diffraction （XRD）, Fourier transform infrared （FTIR）, scanning electron microscopy （SEM） and vibrating sample magnetometer （VSM）. The testing results showed that the composite exhibited the ferromagnetic and electric behaviors, which benefit for the application of electromagnetic interfence.
