“…The bands appearing at ∼1,590, 1,500 and 1,167 cm -1 in the untreated samples are due to stretching vibrations of nitrogen-benzene and nitrogen-quinonoid ring structures in the polyaniline backbone, whereas the band at 1,305 cm -1 is associated with C-N stretching. The band at ∼830 cm -1 corresponds to out-of-plane bending vibration of p-disubstituted benzene ring present in the polymer backbone [29,30]. In the sample treated at 600°C the absorption bands are already clearly changed, and the bending vibration of p-disubstituted benzene ring at 830/816 cm -1 has disappeared.…”

“…The sulfonic group (–SO 3 − ) attached to the nitrogen atom has a strong electron-withdrawing character, and in combination with the steric effects, will increase the oxidizing potential of the aniline monomer [34]. …”

“…For PAN doped with sulfonic acid-containing polymers, the stretching of quinonic rings and benzenic rings show a red shift 12 cm 21 and 8 cm 21 , respectively, because the delocalization of positive charge of ANH 1 @ group deduces electron cloud density of aromatic ring. 25 The peak strength become greater due to benzene superimposition.…”
