Effect of MnCo2O4-Nanoparticles Doped in Polyvinyl Alcohol (PVA) on the Structural and Dielectric Properties

Author(s): A. Zaouali

Single-phase manganese cobaltite (MnCo2O4) nanoparticles were prepared by sol-gel method followed by calcination at 750 °C for 6 hours. The effects of polyvinyl alcohol (PVA)agent on the structural, morphology, electrical and dielectric properties inducedheating characteristics of MnCo2O4 nanoparticles were investigated. The small particle size and narrow size distribution of the MnCo2O4 powders characterized by scanning electron microscopy were ameliorated using PVA agent. Electrical and Dielectric properties of MnCo2O4 nanoparticles studied by impedance spectroscopy showed semiconductor comportment with the highest permittivity and conductivityat room temperature. The MnCo2O4nanoparticles assisted by PVAexhibited the higherdielectric constant of 2500 F m-1comparison with 800 Fm-1for the powders sol-gel without using PVA
