Abstract
Dielectric measurements were made on clay filled polyethylene-ethyl vinyl acetate (EVA) copolymer nanocomposites during processing by extrusion. The results show that composites containing chemically treated clays display significant dielectric dispersions. The addition of natural clay to the EVA copolymer increased the dielectric constant or relative permittivity above that of the EVA copolymer but did not increase the conductivity or cause any dispersion. The chemically treated clays, which are known to exfoliate in the composite with EVA copolymer, gave substantially higher relative permitivity and conductivity and distinct variations with frequency consistent with dielectric relaxations at frequencies below 3000Hz. One clay treatment gave a larger dielectric dispersion than the other.Proceedings Title
