عنوان المقالة: the effect of nano graphene additive on the a.c electrical properties M.R. MHEL, S.I. HUSSEIN International journal of science and research , 6 , 2017
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.
