Conducting polymer nanocylinders have potential applications as diverse as field emitter, magnetic nanocylinder array, organic solar cells, sensors and numerous other fields. Although various methods now exist for making conducting polymer nanocylinders, nanoprecise electrochemical filling in porous templates is an elegant approach for this purpose. However, in general monomer supply into the nano-pores of the substrate is limited in the conventional media, and therefore the low density resulting polymer such as a hallow structure polymer was obtained in the pores. Recently, we have successfully prepared a highly clear and transparent emulsified aqueous solution containing immiscible droplets 3,4-ethylenedioxythiophene, EDOT) with diameters of a few tens of nanometres using 20 kHz → 1.6MHz → 2.4MHz sequential processing with ultrasonic waves (tandem acoustic emulsification). Therefore, it can be expected that these small droplets would enter smoothly into the nano-porous substrate inside and consequently they would be polymerized in the substrate inside to form the solid PEDOT nanocylinders without the formation of a hollow structure. In the present work, the electrochemical synthesis of nanocylindrical PEDOT materials using nano-porous alumina membrane (pore size : (φ200 nm) as a template was successfully carried out in EDOT monomer transparent nanoemulsions. In the presentation, we will also discuss about the SEM observation and electrochemical properties of PEDOT nanocylinders.
