Preparation and Electromagnetic Properties of Ferriferrous Oxide/Polyaniline Composites

Article Preview

Abstract:

By using chemical oxidative polymerization method, ferriferrous oxide/polyaniline (Fe3O4/PANI) composites are successfully synthesized. The composites are characterized by Fourier transform infrared spectra (FTIR), vibrating sample magnetometer (VSM), and vector network analyzer (VNA). With the amount of Fe3O4 increase, the saturation magnetization and remnant magnetization of Fe3O4/PANI composites decrease, while the coercivity remains unchanged. The addition of Fe3O4 makes the reflection loss (RL) of Fe3O4/PANI composites decreases and the microwave absorption increases.
