|Title:||Protonation of the amine nitrogens in emeraldine - evidence from X-ray photoelectron spectroscopy||Authors:||Kang, E.T.
|Issue Date:||Feb-1992||Citation:||Kang, E.T.,Neoh, K.G.,Tan, K.L.,Tan, B.T.G. (1992-02). Protonation of the amine nitrogens in emeraldine - evidence from X-ray photoelectron spectroscopy. Synthetic Metals 46 (2) : 227-233. ScholarBank@NUS Repository.||Abstract:||The protonations of the emeraldine (EM) oxidation state of polyaniline (PAN) by non-volatile protonic acids, such as H2SO4 and HClO4, have been studied by X-ray photoelectron spectroscopy (XPS). The properly resolved N(1s) core-level spectra reveal that a large proportion of the amine nitrogens in the EM base powders and films is also susceptible to protonation when the samples are loaded with excessive non-volatile acids. © 1992.||Source Title:||Synthetic Metals||URI:||http://scholarbank.nus.edu.sg/handle/10635/91664||ISSN:||03796779|
