| Description
| - Interakce jednostěnných uhlíkových nanotub (SWCNT) a vodivého polymeru poly(3,4-ethylendioxythiphene/polystyrenesulfonatu) (PEDOT/PSS) byla studována pomocí in-situ Ramanské spektroelektrochemie. Interakce SWCNT a PEDOT/PSS způsobily částečné dopování SWCNT, které se projevilo ve změně relativní intensity vibračních modů SWCNT. V naší práci poprvé ukazujeme, že in-situ Ramanská spektroelektrochemie je metodou volby pro precizní kontrolu dopování kompositů uhlíkových nanotub s vodivými polymery. Při elektrochemickém dopování SWCNT v PEDOT/PSS je zpožděno vyhasínání RBM a TG modů. Zpoždění je asi 0.2V. Tento rozdíl v potenciálech mizí při silnějším dopování. Zpožděná reakce na dopování byla pozorována jak pro SWCNT tak pro polymer. V případě polymeru je zpoždění specifické pro jednotlivé vibrační pásy polymeru. Během p-dopování většina pásů polymeru postupně vyhasíná. Toto chování se liší od čistého polymeru kde jsou změny nemonotóní. (cs)
- The interaction of single wall carbon nanotubes (SWCNT) and the conducting polymer poly(3,4-ethylendioxythiphene/polystyrenesulfonate) (PEDOT/PSS) was studied by in-situ Raman spectroelectrochemistry. The mixing of SWCNT with PEDOT/PSS caused a partial doping of SWCNT which was indicated by the change of relative intensity of the SWCNT Raman features. We demonstrate for the first time that in situ Raman spectroelectrochemistry is a method of choice for precise and effective control of doping level of composites of conducting polymers and SWCNT. For electrochemical doping of SWCNTs embedded in PEDOT/PSS the bleaching of RBM and TG modes of the SWCNT is delayed as compared to that in pure SWCNT. The delay is of about 0.2 V. This potential difference vanishes at higher potentials. The delayed response to doping is observed for both the SWCNT and the polymer matrix features. In the latter case the response is specific for individual polymer bands.
