HIGH ENERGY ELECTRONS.Electron stimulated ion desorption (ESID) and degradation studies of polypyrrole doped with dodecylsulfate (PPy/DS) deposited on FTO were performed using time-of-flight mass spectrometry (TOF-MS) for ion analysis.The results suggest a strong contribution from fragments of the dodecylsulfate hydrocarbon chain to the mass spectra.In the 650-1500 eV energy range the ion yield curves show maxima at about 600, 1200 and 1400 eV, which can be related to carbon, nitrogen and oxygen-containing ...

After heating up to 800°C in air, the properties of the densified coatings were studied by X-ray Diffraction and FTIR Reflection Spectroscopy. The chemical protection of these coatings against thermal oxidation of the steel in air was determined by weight-gain measurements. Potentiodynamic ...
