In this study, the samples have been prepared by adding rice shell to the poly vinyl alcohol and poly vinyl acetate with different weight percentages (0,5,10,18.104.22.168 and 35) wt%. The A.C electrical properties show that the dielectric constant and dielectric loss of the composites decrease with increasing the frequency of applied electrical field and they increase with the increase of the concentration of the rice shell. The A.C electrical conductivity increases with increasing the concentration of rice shell, increases with the increase frequency, and almost constant at high frequency.
