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. However, there were some flaws of PEDOT:PSS such as low work function(WF), poor electrical homogeneity. To solve these problems, we newly synthesized the star-shaped PSS polymers via Atom transfer radical polymerization (ATRP) in this study. Moreover, we synthesized PEDOT: tri-PSS polymers by oxidative polymerization. polymers were characterized by Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance (NMR). The new PEDOT: tri-PSS polymers 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). |
