摘要：

In order to improve the electrical conductivity of in-situ polymerized poly(3,4-ethylenedioxythiophene) (PEDOT) thin film, we investigated the effect of doping level and co-dopant on the electrical conductivity. Doping level of PEDOT thin film was determined by X-ray photoelectron spectroscopy (XPS) and it was found that the higher doping level led to higher electrical conductivity. We also used several kinds of co-dopants such as methanesulfunic acid, naphthalenesulfonic acid and p-toluenesulfonic acid to increase the conductivity of PEDOT. When methanesulfonic acid was used as co-dopant, electrical conductivity of PEDOT thin film increased up to 1,500 S/cm. It is considered that the enhanced conductivity resulted from higher interchain conduction or more expanded chain structure due to small dopant size of methanesulfunic acid.
