Abstract


This work demonstrates the Electromagnetic interference shielding(EMI) & corrosion resistance of conducting polyaniline (PANI)-Magnetic nanoparticles like Ni ferrite and Fe3O4 composite was investigated and this study shows that efficient and lightweight polymer film materials.The EMI shielding effectiveness was analyzed in the X-band (8.2-12.4GHz), among this composite Ni ferrite shows better corrosion resistance and shielding effectiveness (10dB).


Keywords


EMI shielding, PANI-Ni ferrite/Fe3O4, Tafel plot.
