چکیده:

Conducting polymers continue to be the focus of active research in diverse fields, including electronics, energy storage, catalysis, chemical sensing [1,2]. Polyaniline is unique among conducting polymers in its wide range of electrical, electrochemical, and optical properties, as well as good stability [3]. Polyaniline is typically synthesized by oxidizing aniline monomer either electrochemically or chemically.[4] The most common strategy that has been implemented is to change the oxidizing agent employed in the chemical polymerization reaction. In recent years, the attempts in the preparation of nanomagnet containing conducting polymers have met with limited success. The electrical conductivity values of the γ-Fe2O3/PPy and γ-Fe2O3/PANi nanocomposites were in the range of 0.026-1.9 S/cm, which are far below those (100-600 S/cm) of the parent PPys doped by ASF6-, BF4-, and I3-.[5,6] Peng and co-workers prepared magnetite/polyaniline (Fe3O4/PANi) nanocomposites with core-shell structure
