On the possibility of grafting conducting polymers into insulating ones

Abstract

The possibility of grafting between conducting polymers, like polypyrrole (PPy) and polyaniline (PAn) , and insulating polymers, such as polybisphenol A carbonate (PC) and polyamide (PA), is studied via semi-empirical methods using the AM1 parametrization. Several experimental studies on the issue have previously revealed that a chemical interaction exists between the couples (PAn-PC, PpY-PC and PPy-PA) during the electrochemical synthesis of PAn and PPy in the insulating host matrices. Here we present additional theoretical evidence indicating that such grafting is possible, at least for small oligomers.

Theoretical Investigations into the Structural and Electronic Influences on the Hydrogen Bonding in Doped Polyaniline

“…A number of other semiempirical papers exist on various aspects of PANi. These include grafting of polymers to enhance properties, conformational analysis and UV−vis spectra, structure and energetics of PANi polarons and bipolarons, adsorption onto metal surfaces, and finally substitution effects in diphenylamine …”

“…moiety [g-11]. The reason for the synthesis of such insulating polymers lies in the fact that they are soluble and can easily be reacted with pyrrole or thiophene in solution through electrochemical [ 121 or oxidative chemical methods [13,14]. We have synthesized poly between pyrrole and the pyrrole moiety of Poly B.…”
