Published online by Cambridge University Press: 16 January 2019
Abstract
This work presents a study about synthesis of polypyrrole films electrochemically doped with iodine by luminescent discharge plasma in aqueous sodium sulfate solution, and its structural, morphological and electrical characterization. The synthesis is carried out at atmospheric pressure with square pulse from -1.06 to 1.16 V for 120 minutes. Doping times of the films are 10, 30 and 50 minutes. The films have thicknesses of 6, 12.7, 20.32 and 25.4 μm, and linear growth trend according to the time exposure of their synthesis. The main chemical groups exhibited in the films are C-H, N-H and CH2I, which are characteristics of film doped with Iodine. The electrical conductivity calculated of polypyrrole films is in the range 10-5-10-3 S/cm, and its activation energy is between 0.052 and 1.77 eV.
