Abstract The nanocomposites of BaTiO3 and BaFe12O19 were prepared by sol-gel process, and the (BaTiO3+BaFe12O19)/PANI was prepared by in situ polymerization method. The structure, morphologies and electromagnetic properties of the samples were characterized by means of powder X-ray diffractometer (XRD), Fourier transform infrared (FTIR) spectrometer, transmission electron microscope (TEM), scanning electron microscope (SEM), four-point probe instrument(SDY-4) and vibrating sample magnetometer (VSM). The results show that with the increasing of PANI contents, the magnetization of the composites decreases, and the electrical conductivity increases, the microwave reflectivity absorption strength increase, maximum reflection loss is −27.73 dB, the absorption frequency shift to two-level (high-frequency and low-frequency) direction, and the infrared absorption performance increases.
