الملخص EN

stract In this work, we study the effect of nanosilver particles on electrical properties of polymer matrix consisting of (PVA-PVP).

The samples of PVA-PVP-Ag nanocomposites were prepared by using casting method,for (0, 4, 8 , 12 and 16) wt.% of nanosilver.

The experimental results show that the D.C electrical conductivity for the PVA-PVP-Ag nanocomposite increase with the increasing temperature, the activation energy for D.C electrical conductivity for PVA-PVP-Ag nanocomposite decrease with the increasing of concentrations of the Ag nanoparticles,the dielectric constant, dielectric loss, the D.C and A.C electrical conductivity for PVA-PVP-Ag nanocomposite are increasing with the increasing of concentrations of the Ag nanoparticle, the dielectric constant and the dielectric loss of the PVA-PVP-Ag nanocomposite is decreasing with the increase of frequency of the applied electric field, but the A.C electrical conductivity increasing with the frequency.
