Original Kurzfassung:
In this work the electochemical doping and protonation processes of polyaniline (PANI) are described by using in situ FTIR-ATR and a new doping system NaReO4/HReO4. Cyclic voltammtry shows tha above ca. pH 4 only one wave response can be obtained. With increasing acidity of the electrolyte a two-wave response develops, the splitting of the waves occurring at pH ca. 3.5 - 4. By in situ measurements during the base-acid transition process, a distinct picture of protonation in different forms of PANI has been obtained.
