Kinetics and mechanism of pyrrole chemical polymerization

The Electrochemistry of Fe3O4/Polypyrrole Composite Electrodes in Lithium-Ion Cells: The Role of Polypyrrole in Capacity Retention

“…27 Variations in pH and solvent have also been investigated and showed that a higher acidity is favorable to prepare electrically conductive polypyrrole (PPy). 28,29 Therefore, ptoluenesulfonic acid (HTos) was used in excess to maintain the pH at ∼ 1.5, promoting Fe n+ dissolution from Fe 3 O 4 and initiate oxidative pyrrole polymerization.…”

Electroconducting materials based on polypyrrole

“…Electroconducting polymers can be synthesized using chemical [19][20][21] or electrochemical polymerization [22][23][24][25]. Polymerization by ectropolymerization, metal-catalyzed coupling reactions, and chemical oxidative polymerization was successfully used for synthesis of polymers constructed of heterocyclic (pyrrole, thiophene, furan, etc) [26][27][28][29][30] and aromatic units (phenylene derivatives, aniline) [31][32][33][34][35][36][37], but also photochemical polymerization and polymerization cathalyzed by enzimes has been also applied [38,39] Method of chemical polymerization can be applied for synthesis of all types of conducting polymers, including those which cannot be obtained electrochemically [40].…”

Poly(pyrrole) microwires fabrication process on flexible thermoplastics polymers: Application as a biosensing material

“…The oxidative catalytic polymerization of Py has been vastly studied [41,42,43]. The conductive PPy is an oxidized form, where the backbone contains delocalized charges on the pi electron system, A c c e p t e d M a n u s c r i p t electrical conduction takes place by conduction of these holes.…”
