Title: | In situ conductivity measurements on polyethylenedioxythiophene derivatives with different counter ions | Authors: | AUBERT, Pierre-Henri Groenendaal, L Louwet, Frank LUTSEN, Laurence VANDERZANDE, Dirk Zotti, G |
Issue Date: | 2002 | Publisher: | ELSEVIER SCIENCE SA | Source: | SYNTHETIC METALS, 126(2-3). p. 193-198 | Abstract: | 3,4-Ethylenedioxythiophene (EDT) and thieno-(3,4-b)-2,3-dihydro-2-tetradecyl-1,4-dioxane (EDT C-14) were electrochemically deposited onto Pt using different electrolytes in acetonitrile. The resulting PEDT films containing different counter ions were subsequently characterized and their in situ conductivity values were measured using a two band electrode. The latter showed that the highest conductivities were obtained with ClO4- and BF4- as counter ions. Furthermore, the morphology, and thus the conductive properties, of the films seem to be strongly dependent on the applied polymerization potential.
