الملخص الانجليزي
Composites of Epoxy/Copper have been prepared with different weight percentages (5,10,15,20,25,50%), and the other adding Graphene nanoparticle to Epoxy resin to prepared nanocomposites with different weight percentages (1,3,5,7,9%). Hybrid composites have been prepared with specificweight percentages. The A.C electrical properties were studied to the composites with different weight percents, their contents have been characterized. The A.C electrical properties show that the dielectric constant and dielectric loss of the composites and nanocomposites decrease with increasing of the frequency applied electrical field with range (10KHz-10MHz), and temperature with range (293-373K) The A.C electrical conductivity increases with increasing ofthe frequency and the concentration of Copper and Graphene.The change of A.C conductivity with the amplified electric field frequency is follow to the relationship ( σαωs), where s values were found from this relation. The activation energy decreases for all samples with increasing the concentration of additive Copper and Graphene.
