The improvement of the quality and electrical properties of a film will contribute to the stability and performance of an electronic product during component manufacturing. However, the pristine solution concentration ratio of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) to water is in the range of only 1.0–1.3 wt%. Therefore, the pristine conductivity of PEDOT:PSS is poor because the conductive PEDOT is dispersed in excess water, resulting in the limitation of carrier transmission. In this study, a simple method of removing excess water in PEDOT:PSS solution by heating and stirring is proposed. The heating and stirring of the PEDOT:PSS solution can not only change the structure but also increase the conductivity of the PEDOT:PSS film. It is an effective method of improving the quality and electrical properties of the film simultaneously. Moreover, the fabrication process for the PEDOT:PSS film in this study is different from that of the commonly used multilayer film. A single film of high quality can be obtained in a short process time by heating and stirring. A high-quality single film is better than a multilayer film.
