Raman spectroscopy (RS) is generally used for a qualitative discrimination of the different polyaniline (PANI) forms. The theoretical assignment of the main bands was done satisfactorily in the case of insulating forms, but it is not the same in the case of conductive forms. A new band at 1330 cm -1 empirically observed during protonation is assumed to correspond to the stretching...
An all solid-state electrochromic device (ASSED) formed by polyaniline (PANI) and WO 3 separated by a protonic conductor solid electrolyte, PAMPS, is realized. Its transmission spectrum is checked up to 10 4 cycles extending from -1 to +1 V. The kinetics of coloration/bleaching are studied using Optical Multichannel Analysis (OMA). The roles of WO 3 and PANI in the global coloration...
