**Lecture Abstract** The highest practical electrical conductivity of doped state conductive polymers is 1,000 S/cm for systems where high boiling point polar solvents are added to PEDOT/PSS. Conductive polymer systems like PEDOT/PSS, which exhibit such high electrical conductivity, have already been commercialized as cathode materials for electrolytic capacitors and as transparent antistatic materials. Furthermore, they are emerging as strong candidates for transparent electrodes to replace ITO, alongside materials like carbon nanotubes. However, in all these applications, there is a demand for the development of conductive polymers with even higher electrical conductivity, and reports have begun to emerge of conductive polymers in the research stage showing high electrical conductivities exceeding 3,000 S/cm. Additionally, the introduction of new analytical methods has yielded new insights into the correlation between crystal structure and high conductivity. In this seminar, we will provide a detailed introduction to the mechanisms behind the high conductivity of such systems and offer guidelines for achieving higher conductivity in conductive polymers.
