Abstract
Dielectric measurements were made on clay filled nylon and polyethylene-ethyl vinyl acetate (PE-EVA) copolymer nanocomposites during processing by extrusion. Nylon without clay had a small dielectric dispersion while PE-EVA did not. The addition of natural clay to the PE-EVA copolymer increased the dielectric constant (relative permittivity) above that of the PE-EVA copolymer but did not increase the conductivity or cause any dispersion. In both PE-EVA and Nylon, addition of chemically treated clays gave substantial increases in dielectric dispersion that are associated with the intercalated or exfoliated state. Xray diffraction measurements were made on the composites.Citation
