Intrinsically conductive polymers like polyanilines, polypyrrols and polythiophenes become conductive by removing an electron from their conjugated π-orbitals via doping. The electrical conductivity results from the delocalization of electrons along the polymer backbone - hence the term “synthetic metals”. For three decades conductive polymers have been an area of intense research and in the year 2000 Alan Heeger, Alan MacDiarmid, and Hideki Shirakawa received the Nobel Prize in Chemistry “for the discovery and development of conductive polymers." Clevios™ PEDOT:PSS is a substituted polythiophene ionomer complex with a polyanion that offers the highest conductivity found so far in a commercial product : 1000 S/cm. The product is offered as the monomer for in-situ polymerisation, as neat water based dispersions or as ready-to-use formulations mixed with solvents and additives.
