This work presents the synthesis of nano and meso spherical iodine doped particles of polypyrrole using glow discharges of pyrrole. The synthesis produced polypyrrole powder with the purpose of using the polymers in bioelectric applications. The powder was composed of homogeneous spheres of diameter between 35 and 350Â nm, which arranged in agglomerates of several micrometers. A molecular simulation approach of polypyrrole nanoparticles was done considering full networking of 12 pyrrole rings joined in hexagonal arrangements. In those conditions, spherical particles can be obtained with a minimum diameter of approximately 1.4Â nm. The inclusion of iodine atoms is difficult in such particles, however as the particles grow, iodine compounds produced in the chemical reactions can be trapped or adhered to the particles. The electric conductivity of polypyrrole powder as a function of relative humidity was in the interval 10â9-10â6Â S/m.
