Synthesis and Characterization of Polyaniline/ CoxCr0.5-xFe2O4 Nanocomposites for ElS Applications | Chapter 2 | New Innovations in Chemistry and Biochemistry Vol. 5

 Polyaniline (PANI)/CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites with good electromagnetic shielding efficiency were synthesised by in situ polymerization. PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites were investigated using X-ray diffraction, Field emission scanning electron microscopy, and Vibrating sample magnetometer techniques. At room temperature, EMI shielding effectiveness (SE) tests for PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites were performed as a function of frequency. The electron hopping model describes the conduction mechanisms in PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites. Furthermore, in all generated samples, SE was shown to decrease as the applied frequency was increased. In the current work, SE values for Polyaniline/CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites increase as the Copper content in the composite increases.
