ArboPyr: Material- und Verfahrensanalyse zur Erzeugung von Kohlenstoffstrukturen in naturfasergefüllten Polymeren für den Einsatz in der Brennstoffzellentechnik. - In: Netzwerke Grundlagenforschung erneuerbare Energien und rationelle Energieanwendung, ISBN 978-3-89336-485-5, (2007), S. 121-133
Durch steigenden Bedarf an transportablen und effizienteren Energiequellen ist die Nachfrage nach Methanolbrennstoffzellen entsprechend hoch. Mit dem Ziel, hierfür benötigte Bipolarplatten kostengünstiger und umweltschonender zu produzieren, werden aus naturfasergefüllten Polymeren Platten durch Spritzgussverfahren hergestellt. Es wurde eine umfangreiche Charakterisierung der Proben mit TGA, XPS, EELS, XRD, TPD, DSC und NMR durchgeführt. Es hat sich gezeigt, dass durch die Pyrolyse gut leitfähige Materialien entstehen, die für den Einsatz in der Brennstoffzelle hervorragend geeignet sein können. Die Ergebnisse wurden in Hinblick auf die weitere Entwicklung der Bipolarplatten diskutiert.

Temperature-dependent electronic and vibrational structure of the 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide room-temperature ionic liquid surface : a study with XPS, UPS, MIES, and HREELS. - In: The journal of physical chemistry, ISSN 1520-5207, Bd. 111 (2007), 18, S. 4801-4806
The near-surface structure of the room-temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) amide has been investigated as a function of temperature between 100 and 620 K. We used a combination of photoelectron spectroscopies (XPS and UPS), metastable induced electron spectroscopy (MIES), and high-resolution electron energy loss spectroscopy (HREELS). The valence band and HREELS spectra are interpreted on the basis of density functional theory (DFT) calculations. At room temperature, the most pronounced structures in the HREELS, UPS, and MIES spectra are related to the CF3 group in the anion. Spectral changes observed at 100 K are interpreted as a change of the molecular orientation at the outermost surface, when the temperature is lowered. At elevated temperatures, early volatilization, starting at 350 K, is observed under reduced pressure.
