Comparative study of polyaniline cast films prepared from enzymatically and chemically synthesized polyaniline

Improved performance of polyamide thin-film composite nanofiltration membrane by using polyetersulfone/polyaniline membrane as the substrate

“…The bands at 1165 cm À 1 and 831 cm À 1 were due to the aromatic C-H bending in the plane and out of the plane aromatic ring. These characteristic peaks were consistent with the FTIR spectra of PANI in the reported literature [26,32,33].…”

NO2 gas sensing with polyaniline nanofibers synthesized by a facile aqueous/organic interfacial polymerization

“…The peaks at 1302 and 1162 cm −1 correspond to C N stretching of the secondary aromatic amine and C N stretching, respectively. The peaks at 1110 and 824 cm −1 are attributed to the aromatic C H bending in the plane and out of the plane for the 1,4-disubstituted aromatic ring [18,19]. The peaks between 800 and 600 cm −1 can be assigned to the vibration of C H bands in the benzene rings.…”

“…The characteristic peaks at 1598 and 1562 cm −1 are assigned to the C C stretching modes of the quinoid ring in the emeraldine base and emeraldine salt, respectively. The peak at 1489 cm −1 corresponds to the C C stretching mode of the benzenoid ring of the leucoemeraldine component [16,17,19]. The peaks at 1302 and 1162 cm −1 correspond to C N stretching of the secondary aromatic amine and C N stretching, respectively.…”

Polyaniline–DNA based sensor for the detection of anthracycline drugs

“…Polyaniline (PANI) is a product of oxidative polymerization of aniline commonly performed in strongly acidic conditions by treatment with oxidants ((NH 4 ) or electrochemically, commonly by multiple cycling the potential of the electrode [21][22][23]. The electrochemical synthesis is most preferable for sensor assembling because the polymer is directly precipitated on the electrode.…”
