“…The latter is based on data for the polymerization and redox charges and should be also an estimate for doping. PSSA-doped PANIs were studied by means of XPS in several cases [13][14][15][16] but information on their electrochemical behavior obtained with the same materials was not communicated. In some cases [13,16] PANI was obtained chemically but electrochemical studies were not in the focus of interest.…”

Polyaniline (PANI) layers are electrochemically obtained in the presence of four polysulfonic acids with different rigidities of the polymer backbone-iso-(and tere-)poly-(4,4′-(2,2′-disulfonic acid)-diphenylene-iso(tere)-phthalamide (i-PASA and t-PASA), polystyrenesulfonic acid (PSSA) and poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA). Combined microgravimetric (EQCM) and electrochemical measurements are carried out in the course of polymerization and repetitive redox switching. It is found that after synthesis PASA-doped PANIs shows good stability with low exchange of mass in the course of voltammetric scans, while PAMPSA-doped PANI contains a large amount of water that gradually becomes expelled in the repetitive redox switching. PANI obtained in the presence of PSSA takes an intermediate position with respect to mass exchanged in the electrochemical redox process. XPS studies are used to obtain data for the extent of doping of the different PANI materials. The results show high doping level (about 0.5) for PASA- and PAMPSA- and lower level (0.32) for PSSA-doped PANI layers. Repeated electrochemical studies carried out with the specimens investigated by XPS after long-term storage in the dry state give evidence for structural rearrangement, perfect recuperation of the initial electrochemical activity and high stability of the electrochemical response.

“…The peak at 1505 cm À1 corresponded to symmetric vibration of NÀ ÀCÀ ÀN in the urethane-aniline because of the reactions of the À ÀNCO groups with the NH 2 groups of the PANi [27]. A characteristic band of the conductive form of PANi was observed at 1308 cm À1 , which was due to p-electron delocalization induced in the polymer by protonation [28]. The adsorption peak at 1224 cm À1 was assigned to a CÀ ÀN + stretching vibration in the polaron structure.…”
