Modeling of electrical and Dielectric Properties for Ethylene Vinyl Acetate (EVA)/Polyaniline Conductive Composites prepared through In-Situ Polymerization ?f Aniline in EVA Matrix

摘要

Ethylene Vinyl Acetate (EVA)/polyaniline (Pani) composites were prepared by In-situ polymerization technique. Different theoretical models to predict DC conductivity and permittivity of the composites have been proposed. The limitations of the models as well as the deviations between the theoretically predicted and experimentally observed results have been discussed. Two new models one for conductivity and the other for permittivity have been proposed which fit well with the experimentally observed results. Keywords: In-situ synthesis, Conductivity, Dielectric property, Modeling.
