The oxidation of aniline with p-benzoquinone and its impact on the preparation of the conducting polymer, polyaniline

The observation of a conductivity threshold on the electrorheological effect of p-phenylenediamine oxidized with p-benzoquinone

“…p-Benzoquinone is thus not a mere oxidant, as it is included in the final structure of oligomers. 33,38,39 When the reaction is carried out in the solutions of MSA the corresponding methanesulfonate salts are produced ( Fig. 1 (2)).…”

“…However, oligomers of conducting polymers prepared in the presence of p-benzoquinone forming trimers do not contain the conjugated system. Thus, the conductivity of oligomers can be then understood as a result of an inter-molecular charge transport, 32,33 where the delocalized electrons are responsible for the hole transport and hydrogen bonding interactions influencing the electron transport. 34 The doping process is then crucial for the conductivity of such oligomers.…”

Complex Optical Studies on Conducting Polypyrrole Doped with ZnO Nanoparticles

“…Polymer nanocomposites in recent years have become one of the most extensively studied materials all over the world due to their unusual properties of the synthesis of conducting polymers such as polyaniline (PANI), polypyrrole (PPy), and polythiopene (PTh) due to their high electrical conductivity, interesting electrochemical properties, and easy processability. [1][2][3] These electrical and electrochemical properties of such conducting polymers show much assurance for commercial applications in battery materials, electrochromic devices, sensor technology, and nonlinear optics (NLO). [4] In recent years, several applications for the control of band gap are essential for light-emitting diodes (LEDs) transparency in the visible region combined with high electrical DOI: 10.1002/masy.202000096 conductivity, etc.…”

Carbonization of aniline oligomers to electrically polarizable particles and their use in electrorheology

“…Polyaniline, as a material for electrorheology, has been reported in many scientific papers due to its easy and inexpensive synthesis [5,8,[11][12][13][14][15][16][17][18]. Moreover, aniline-like oligomers with tuneable conductivities prepared by different reaction conditions or reaction substances have been introduced [19][20][21].…”
