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 |
