Conductivity and stability in ion-implanted polyaniline

Abstract

We have ion-implanted substituted polyaniline, an inherently conducting polymer, in order to determine the relationship between the electronic transport in chemically doped polymers and electronic transport in ion-implanted polymers. The polyaniline films were implanted with N2+ ions and B+ ions at 50 keV to fluences between 1 × 1016 and 5 × 1016 ions/cm2. The post-implanted materials have many of the characteristics of ion-implanted polymers; including increased hardness and densification. We also discovered that ion-implanted polyaniline is more than one order of magnitude less sensitive to ambient water vapor. The electronic properties of ion-implanted polyaniline were very similar to other ion-implanted polymers, and indicated that a conductivity term present in unimplanted polyaniline was destroyed or dominated after implantation. © 1993.
