Title: | Morphological study of a poly (3,4-ethylenedioxythiophene)/polystyrenesulfonic acid mixture by solid state C-13-CP/MAS NMR, relaxometry | Authors: | ADRIAENSENS, Peter CARLEER, Robert STORME, Liesbet VANDERZANDE, Dirk GELAN, Jan |
Issue Date: | 2002 | Publisher: | ELSEVIER SCI LTD | Source: | POLYMER, 43(25). p. 7003-7006 | Abstract: | The nanometer morphology of a mixture of the electrically conductive polymer poly(3,4-ethylenedioxythiophene) and polystyrene-sulfonic acid is studied by means of solid state C-13-CP/MAS NMR relaxation experiments. Based on the T1H and T1pH NMR relaxation decay times, determined via the chemical shift selective carbon resonances, it can be concluded that the mixture is homogeneous on the nanometer scale. Consequently, charge transport (hopping) between PEDT chains is hindered, resulting in antistatic properties. (C) 2002 Elsevier Science Ltd.
