Conductivity relaxation behavior of interpenetrating polymer network composites of polypyrrole and poly(styrene-co-butyl acrylate)

Abstract

Conductivity relaxation spectra of interpenetrating network conducting composites of polypyrrole (PPy) and poly(styrene-co-butyl acrylate) (SBA) have been analysed on the basis of coupling model developed by Ngai. The macroscopic activation energy obtained from coupling model using the stretch exponent β compares favourably with the tunnel energy estimated from the overlapping large polaron tunnelling (OLPT) model. © 2000 John Wiley & Sons, Inc.
