Synthesis and properties of electrically conducting polymers from aromatic amines

The electrical measurements in poly(2-chloroaniline) based thin film sandwich devices

“…From FTIR bands (Fig. 2a), it was found that polymerization occurs with head to tail coupling [43]. The 1160 and 1200 cm − 1 bands belong to the -N_Q_N or B-NH-B (where B denotes benzenoid and Q denotes quinoid ring) vibration bands of P2ClAn.…”

“…The mobility value in conjugated polymers has been reported around 10 − 4 cm 2 V − 1 s − 1 and it is known to depend on the field [63]. Furthermore, such as in PANI [43][44][45], it could also be used Al/P2ClAn contacts with CH 3 COO − anion as switching or memory elements.…”

Processable polyaniline-HCSA/poly(vinyl acetate-co-butyl acrylate) corrosion protection coatings for aluminium alloy 2024-T3: A SVET and Raman study

“…The band observed at 1169 cm −1 corresponds to two peaks not clearly separated: the C H stretch of the quinoid ring at 1163 cm −1 and the C H stretch of the benzoid ring band observed at 1178 cm −1 [18]. The band observed at 1590 cm −1 can be ascribed to the stretching mode of the C C bond in the quinoid ring with a small shoulder at 1603 cm −1 assigned to the stretching mode of the benzoid ring (C C bond) observed at 1610 cm −1 [20,21].…”

Oxidative Polymerization of Aniline: Molecular Synthesis of Polyaniline and the Formation of Supramolecular Structures

“…It is formed as a result of strictly regular assembly of monomer units. The chain of conducting PANI contains more than 95% of para-substituted aniline fragments linked in a "head-to-tail" configuration (Hagiwara et al 1987). Defects in this regular structure arising during copolymerization of aniline with other monomers or after introduction of aniline units with another configuration (ortho-or meta-substituted fragments) lead to dramatic decrease in conductivity.…”
