  • Polyethylenedioxythiophene-polystyrenesulfonate (PEDOT:PSS, BAYTRON® P) is a versatile, solution-processable inherently conductive polymer useful for making transparent conductive and antistatic films.
  • Understanding the basic structural properties of the PEDOT:PSS polymer and its chemical & physical interactions with a variety of coating additives enables end-users to prepare stable, easy-to-use coating dispersions and even to print PEDOT/PSS polymers using e.g. silkscreen printing.
  • In addition to highly conductive PEDOT/PSS dispersions H.C. Starck also produces wet-processible organic semiconductors. A new class of organosilicon oligothiophenes, Ampertron™ SD, has been tested successfully as a semiconducting layer in organic thin film transistors.

Speaker Biography (Detlef Gaiser)

Detlef Gaiser is a chemist working at H.C. Starck Leverkusen, Germany. He is a manager for application engineering for CLEVIOS P (PEDOT/ PSS) dispersions and Ampertron™ oligothiophenes for the use in polymer electronics. He obtained his diploma and Ph.D. from the University of Cologne, Germany, studying the "Synthesis and Properties of New Zirconium N-Donor Complexes". In 1998 he joined the Electronic Chemicals group of the Bayer AG, Leverkusen, as a research chemist working on the synthesis of the BAYTRON® M monomer. In 2002 he transferred to H.C. Starck, Leverkusen and worked as a plant manager for colloidal silica. In 2006 he joined the CLEVIOS P application engineering team.
