Intensity of this peak is significantly reduced upon electrochemical reduction. Atomic concentrations derived from the observed N+ and F (stemming from the dopant BF4-) peaks reveal a slightly higher cation/anion ratio for this composite and suggest that the composite has a different chemical composition than the corresponding polymers. © 1995 Elsevier Science B.V.EnglishBinding energyElectrolytic reductionFluorinePhotoelectron spectroscopyHotoelectronsPhotonsPolypyrrolesX-ray photoelectron spectroscopyAtomic concentrationChemical compositionsPolyamide compositeSpectroscopic investigationsX-ray photoelectron spectraArticle10.1016/0022-2860(95)08754-J
