Conducting polymers have been investigated widely for various applications. The fine conductive polymer particles is required to be synthesized by chemical oxidative polymerization, because of its poor processability. We focused on the water dispersed monomer polymerization assisted by ultrasound under a low oxidant concentration. In particular, ultrasonic polymerization permits the use of lower surfactant concentrations and obviates the need for initiators. In this study, the polypyrrole and PEDOT/PSS particles were synthesized, and effects of ultrasonic frequency on the size and morphology of the synthesized conducting polymer particles were investigated. In the case of polypyrrole particles synthesis, the spherical polypyrrole particles were synthesized, and the size and morphology of particles were not influenced by the frequency. In addition, the synthesized polypyrrole particles were not also influenced by the ultrasonic irradiation. On the other hand, in the case of PEDOT/PSS particles synthesis, the particle size distribution was influenced by the frequency. The particle distribution became narrow with increasing ultrasonic frequency, and monodispersed particles were synthesized.
