Most electrical properties have been investigated of polymer nanocomposites films constructed by pressure technique. This research includes some (A.C & D.C) electrical check for (PMMA-Cu) polymer nanocomposites with various concentration as (0, 10, 20, 30, 40, 45 and 50) wt. % of (Cu). The A.C electrical properties state that the insulation constant and isolation loss increase with rising of the concentration of nanoparticles, and they reduce with raising the frequency of applied electrical field. Increasing the temperature at various concentrations of (Cu) nanoparticles shows that there is a rising D.C. conduction of the nanocomposites. Raising the concentrations of the nanoparticles additives leads to reduce effective energy. The SEM has been used for identification of the changes occurred within the microstructure of the shaped or rotten phases.
