Electrical Heating Properties of PEDOT Thin Film Prepared by In Situ Polymerization

Abstract:

Poly (3, 4-ethylenedioxythiophene) (PEDT) has attracted a great deal of interest during the last decades. PEDOT was popular with many applications such as antistatic coating, the hole injection layer in OLED. The thermal stability of PEDOT is important in these applications. In this study, PEDOT films were prepared by oxidative polymerization on the substrate polyimide (PI) films. Matrix polymer poly (vinyl prrrolidone) (PVP), Monomer 3, 4-ethylenedioxythiophene), retardant were dissolved in solvent as monomer solution; The Iron (III) p-toluenesulfonate hexahydrate (FTS) was used as oxidant solution. To investigate the heating properties of PEDOT films, the content of PVP, oxidant FTS, retardant were varied. The influence of treatment current density was also studied. Thickness of the PEDOT film was measured by Alpha-step surface profiler and the surface resistivity was measured by multimeter.
