✦ Synopsis

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 ␤ compares favourably with the tunnel energy estimated from the overlapping large polaron tunnelling (OLPT) model.

To date, most interpenetrating polymer networks (IPNs) are developed for slow processes such as casting or coating. For industrial manufacturing, fast-reactive polymer processing is often required. Simply increasing the amount of catalyst and/or free-radical initiator shows some limitations. Also, i
