| Abstract |
The increased development and use of electronic devices have led to a new kind of pollution known as electromagnetic interference(EMI). Many researchers have investigated the efficient shielding methods to reduce EMI. Based on the magnetic or dielectric loss, a variety of EM wave absorbing materials have been designed and developed such as ferrites, conducting polymers and so on. The aim of this work is to find out the effect of magnetic nanoparticles of different shapes on the microwave absorption properties and EMI shielding effectiveness of the nanocomposite with magnetic nanoparticles and polyaniline(PANI). In this work, spherical Fe3O4 nanoparticles and hexagonal plate BaFe12O19 nanoparticles are synthesized by hydrothermal reaction. The X-ray diffraction patterns, scanning electron microscopy images and infrared spectroscopy confirmed the formation of polyaniline coating and core magnetic nanoparticles. We have studied the EMI shielding effect and EMI shielding mechanism of magnetic nanoparticles of different shapes in the range of 1-18 GHz. |
