Nanocomposites were usually used for different fields in an industrial applications with low cost and low weight. In this paper, nanocomposites from polyvinyl alcohol- polyethylene oxide- iron oxide nanoparticles have been fabricated. The iron oxide nanoparticles were added to polymer blend by different weight percentages are (2, 4 and 6) wt.%. The structural and dielectric properties of (PVA-PEO-...
