Abstract

Polypyrrole (PPy)/Fe~3~O~4~ nanocomposites were in situ synthesized using chemical oxidative polymerization in an aqueous solution of FeCl~3~.6H~2~O, in presence of different Fe~3~O~4~ loadings (0%–16.52%). These composites were characterized through a 4 Probe electrical conductivity measurement technique, Fourier Transform infrared spectroscopy, energy dispersive X‐ray spectroscopy, scanning electron microscopy, X‐ray diffraction, thermo gravimetric analysis, and vibrating sample magnetometer. Results showed maximum electrical conductivity of 75.28 S/cm for the 2.52% Fe~3~O~4~ loaded nanocomposite and with improved thermal stability compared with the host PPy. Furthermore, a linear relationship between saturated magnetization M~s~ and % composition of Fe~3~O~4~ in the above nanocomposites was observed, showing 6.34 emu/g at 16.52% Fe~3~O~4~/PPy nanocomposite.
