Abstract
Inthepresentwork,nanocompositesofpolyvinylalcoholandaluminananoparticles,have beenpreparedbycastingtechnique.Thealuminananoparticleswereaddedtopolyvinylalcoholwithdifferentconcentrationsare(0,4,8,12and16)wt.%.Theelectricalpropertiesof nanocompositeswerestudied.TheexperimentalresultsshowedthattheD.Celectricalconductivity increases with increase the alumina nanoparticles concentrations andtemperature.The activation energy of D.C electrical conductivity decreases with increase of alumina nanoparticle concentrations," and by findthe samples by the microscopic photographs.
