Polystyrene/magnetite nanocomposite synthesis and characterization: investigation of magnetic and electrical properties for using as microelectromechanical systems (MEMS)

In this work, a novel polystyrene/Fe₃O₄ nanocomposite prepared by in-situ method is presented. Magnetic Fe₃O₄ nanoparticles were encapsulated by polystyrene. The FT-IR spectra confirmed polystyrene/Fe₃O₄ nanocomposite preparation. The electrical properties of prepared nanocomposite were investigated by cyclic voltammetry (CV). The CV analysis showed good electrical conductivity of the synthesized nanocomposite. Magnetic properties of the nanocomposite were studied by vibrating sample magnetometer (VSM). The VSM analysis confirmed magnetic properties of the nanocomposite. The morphology and the size of the synthesized nanocomposite were investigated by field emission scanning electron microscope (FESEM). According to the VSM and CV results, such nanocomposite can be used in microelectromechanical systems.
