Core-Shell Structured Nanocomposites with Electromagnetic Properties

Abstract:

The electromagnetic nanocomposites with a core-shell structure are synthesized by in situ chemical oxidative polymerization. The Co doped Fe3O4 magnetic particles (Co-Fe3O4) act as the core and poly (3,4-ethylenedioxythiophene)-poly (sodium-p-styrenesulfonate) (PEDOT-PSS) as the conductive polymer shells. The morphology, structure, crystallinity, conductive and magnetic properties were studied by transmission electron microscopy (TEM), Scanning electron Microscope (SEM), Fourier Transform Infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), four-probe conductivity meter and vibrating sample magnetometer (VSM). It is found that the core-shell nanocomposites exhibit controllable electromagnetic properties by adjusting the molar ratio of Co-Fe3O4 to EDOT monomer.
