Co-doped ZnO–PVA Nanocomposite for EMI Shielding

Abstract

The article describes the mechanical properties and electromagnetic shielding of Co-doped ZnO–poly(vinyl alcohol) nanocomposite. Significant improvements in mechanical properties can be obtained by incorporating inorganic nano fillers. The E-modulus and tensile strength were found to be enhanced with the increase in the doping concentration of Co.05Zn.95O incorporated in PVA matrix. Further, we have observed that electromagnetic shielding of the composite filled with 2 wt% concentration of Co.05Zn.95O in the PVA matrix exhibited utmost reflection loss of − 47.31 dB in the bandwidth 8–12 GHz which may be attributed to good compatibility of dielectric and magnetic properties of materials.
