In the late 20th century, performances of organic optoelectronic devices have rapidly progressed thereby the demand for flexible devices has intensively been on the rise these days. Indium tin oxide (ITO) is the most popular material as a transparent conductive electrode for optoelectronic devices because ITO has great electrical and optical properties. For flexible devices, ITO, however, has a crucial weak point in the aspect of mechanical property. Therefore many scientists have proposed lots of materials such as graphenes, carbon nanotubes, metal nanowires and conductive polymers. Poly(3,4-ethylenedioxythiophene) (PEDOT) is a very attractive candidate for flexible optoelectronic devices. In order to improve the conductivity of PEDOT:PSS, it is important to effectively remove PSS as an insulator. Our research group introduced dynamic etching process, new one-step method, which simplify complicate process and obtain the same effect with other process. |
