Enhanced optical and electrical properties of PEDOT via nanostructured carbon materials: A comparative investigation

Abstract

Addressed herein, novel poly(3,4 ethylenedioxythiophene) PEDOT/Nanocarbon Materials (NCMs) composite films have been produced by electropolymerization of EDOT monomers onto NCMs coated indium tin oxide (ITO) glass slides. In this study NCMs/ITO working electrodes were prepared by drop casting method which is simpler, quicker, cheaper and easier than other methods. Then PEDOT/NCMs composite films have been produced and investigated by comparing the electrochemical properties with each other in this study. These novel materials significantly improved conductivity and electrochemical performance of PEDOT such as stability of electrochromic characteristics, coloration efficiency, switching time due to an important role in the electron transfer between NCMs and PEDOT films. The prepared novel PEDOT/NCMs composites exhibit excellent optical contrast that is 2 times higher than that of others. These nanocomposite films can be used for electrochromic and energy storage devices applications in near future.
