In this article, conductive and magnetic nanocomposites composed of polypyrrole (PPy), magnetite (Fe 3 O 4 ) nanoparticles (NPs), silver (Ag) NPs, have been successfully synthesized with a two step process. First, the PPy/Fe 3 O 4 was prepared by the ultrasonic in situ polymerization. Next, the PPy/Fe 3 O 4 /Ag was synthesized through the electrostatic adsorption. The products were characterized by fourier‐transform infrared (FTIR) spectroscopy, Scanning electron microscopy (SEM), Thermogravimetric (TG), conductivity and magnetization analysis, and the results showed that the Ag NPs with the good conductivity coated uniformly on the surface of PPy/Fe 3 O 4 and improved the conductivity of PPy/Fe 3 O 4 /Ag composites. In addition, as compared with PPy/Fe 3 O 4 , PPy/Fe 3 O 4 /Ag composites also have the excellent electro‐magnetic property and enhanced thermostability. POLYM.
