Attempts were made to plasma deposit an oriented pi-conjugated polymer of pyrrole (Py) on paper surfaces in order to produce electrically conductive layers. The N/C atomic ratio of 0.13-0.24 was observed for all treatment conditions. This implies the nature of the deposition formed on the paper surface via pulsed plasma is different from that of pyrrole monomer. An increase in conductivity of all pyrrole-plasma treated papers was observed. The 50 W RF-power with 5 min plasma exposed paper sample shows 8.15 x 10(-9) conductivity. The conductivity measurements indicated a plasma-enhanced ring-opening reaction mechanism of pyrrole. (c) Versita Warsaw and Springer-Verlag Berlin Heidelberg. All rights reserved.
