Abstract

The use of conductive polymers has become popular in several areas of activity, with PEDOT:PSS being the most prominent material among them. The notoriety of PEDOT:PSS arises from the ability to conduct electrons, from the interaction with ionic species, in addition to its high stability in operation. Thus, the presence of this material in research and development laboratories in the field of organic electronics is almost mandatory. However, the production and commercialization of PEDOT:PSS inks is concentrated in only one company, causing obstacles to the development of device technologies and advances in the synthesis and obtaining of this material. In this work, we intend to apply concepts developed in the field of decontamination of pollutants in the polymerization of PEDOT:PSS. In both areas advanced oxidative processes (AOPs) are used, however the study of the impact of these AOPs during the synthesis of PEDOT:PSS has not been carried out extensively. Therefore, the intention of this project is the application of knowledge of AOPs in order to increase the redox potential of oxidizing agents, in order to increase the electrical conductivity of the produced paints.
