This summer, TDA’s intrinsically conducting polymers went on sale through Sigma-Aldrich. TDA’s polymers are based on the Poly(3,4-ethylenedioxythiophene) (PEDOT) core developed by Bayer, but are easily processible and compatible with a wide variety of device manufacturing processes because they are soluble in organic solvents. TDA introduced two families of product, the Oligotron™ line of printable (polymerizable) oligomers and the Aedotron™ line of processible, transparent, conducting polymers. More.
The five materials in the line provide the range of properties needed for their different applications, which include conducting films, anti-static layers, organic electronics, conducting inks for printed applications, flexible circuits and TFTs, transport laters in OLEDS and organic solar cells.
The range of properties provided by the materials are listed below, along with links to their respective product fact sheets and the Sigma-Aldrich catalogue.
