ABSTRACT
Background:In this research, many samples have been prepared by adding titanium nanoparticles to the poly vinyl alcohol and poly vinyl acetate with different weight percentages (o, 4, 8,12 and 16) wt%.Objective: The effect of titanium nanoparticles concentration on the D.C and A.C electrical properties have been investigated.Results: showed that the D.C electrical conductivity of such nanocomposites increased with increasing of weight percentages of titanium nanoparticles, and the activation energy changed with increasing of titanium nanoparticlesconcentration.Conclusion: The A.C electrical properties show that the dielectric constant and dielectric loss of the nanocomposites decrease with increasing the frequency of applied electrical field and they increase with the increase of the concentration of the titanium nanoparticles. The A.C electrical conductivity increases with increasing the concentration of titanium nanoparticles, increases with the increasefrequency, and almost constant at high frequency.
