The Effect of Nano Graphene Additive on the A.C Electrical Properties for Epoxy-Copper Composites
M. R. Mhel S. I. Hussain
Abstract: 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 specific weight 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 of the 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 ( s), where s values were found from this relation. The activation energy decreases for all samples with increasing the concentration of additive Copper and Graphene.
