Graphene Oxide Nanoparticles Influence on the Electrical Properties of (PVA– PEG ) Blend

In this study, we preparation polymer blend (PVA-PEG) for three samples in different Molecular weight of PEG ( 4000-8000- 20000 g/mol) then preparation anther three samples polymer Nanocomposites (PVA-PEG-GO) by adding Graphene oxide nanoparticles (GO) concentrically (0.01wt) to blend polyvinyl Alcohol (PVA) and Polyethylene colacyl by using casting method after that study the Electrical properties (A-C) and structure (FTIR) and Optical Microscope enlargement (10x). The results of the study showed the effect of the addition of Graphene oxide on the alternating electrical properties have shown that the insulation constant. The electrophoresis and isolation loss of polymer compounds (PVA-PEG-) are reduced with increasing frequency of the electric field dominant and dielectric loss increases with increasing PEG concentration. The results showed that the alternating electrical conductivity of polymeric composite increased with increasing frequency and molecular weight of all prepared composite. It was also shown that the increase of electrical conductivity significantly with samples of poly nanoparticles (PEG-PVA-GO) by increasing the molecular weight of PEG and be at the highest molecular weight (20000g / mol).
