Poly(3,4-ethylenedioxythiophene) doped with poly (4-styrenesulfonate acid) (PEDOT: PSS), well-known as the most remarkable conducting polymer has applied in many areas due to its good film-forming properties, high transparency, tunable conductivity, flexibility, and excellent thermal stability. In this study, we newly synthesized the PSS random copolymers using the alkyl group, tetrafluorostyrene group, and pyrene group via radical solution polymerization. Moreover, we synthesized PEDOT: PSS random copolymers by oxidative polymerization. Copolymers were characterized by Fourier transform infrared spectroscopy (FTIR). Three new PEDOT: PSS copolymers can be observed wide absorption bands from 400nm to 1650nm.The morphology of three conductive PEDOT: PSS thin films was observed by Atomic Force Microscope (AFM). The electrical properties of three conductive PEDOT: PSS thin films were evaluated by studying the influence of the PA; TF content on the electrical properties.
