Polypyrrole is one of the most important conductive polymer and this research aimed at producing polypyrrole nanoparticles through electrospraying. As polypyrrole cannot be easily dissolved, its direct electrospraying was not possible, pyrrole monomer was electrosprayed on a layer of ferric chloride oxidant with and without paratoluene sulfonic acid as dopant. It was found out that the conditions of the oxidant layer plays an important role in the formation of polypyrrole nanoparticles. It was also found that higher voltage leads to smaller and more uniform particles. Lowering the feed rate in the range of 0.04 – 0.2 ml/h with constant voltage conditions leads to smaller particles. Voltage proved to have a more pronounced effect on the size of electrosprayed polypyrrole nanoparticles. The smallest of polypyrrole nanoparticles (average size:187 nm) were obtained when solution was contained of Pyrrole(80% w/v), ethanol(20% w/v), and the dopant(8% w/v) electrosprayed on ferric chloride with feed rate of 0.04 ml/h, voltage of 26 kV and nozzle collector distance of 20 cm. Key words: Conductive polymers, Polypyrrole, Electrospraying, Nanoparticles.
