Synthesis and Characterization of Soluble Polypyrrole

Chemical synthesis and charge transport mechanism in solution processed flexible polypyrrole films

“…Several attempts have been made in the past to improve the processing and hence application by preparing blends and composites containing conducting PPy [12][13][14][15]. In addition to composite preparation, approaches have been reported to increase the solubility by employing long chain counter ions as dopant in the PPy backbone [16][17][18][19][20]. The poor processing ability of PPy is due to strong interchain interactions and by introducing these long chain counter ions in the resultant PPy the interchain interactions becomes weaker and its solubility increases in certain organic solvents.…”

Synthesis and characterization of polypyrrole doped with anionic spherical polyelectrolyte brushes

“…Lee et al [7] developed DBSA with surface-active properties as anionic additive to realize pyrrole (Py) solvation. Further studies pointed out that adding other large dopants could reduce the interchain links, resulting in the increase of the conductivity and solubility [8][9][10][11]. In view of this, anionic spherical polyelectrolyte brushes (ASPB), consisting of anion polyelectrolyte chains affixing to the surface of spheres, may be novel conducting polymer dopant by introducing the brush polymer with certain functional groups.…”

Highly Conducting Polypyrrole/Cellulose Nanocomposite Films with Enhanced Mechanical Properties

“…by casting of partially dissolved PPy in organic solvents, [19][20][21] is that the formers can be performed in aqueous medium. [22] So far, the conductivity of these composites is still not comparable to that associated to solvent-cast PPy films.…”

“…[17][18][19][20][21][22][23][24][25][26][27] Polymerisation was carried out by passing the oxidant solution (FeCl 3 ) through Cladophora/Py cakes. PPy grew around cellulose microfibres creating a high surface exchange area, which provided the composite good charge-discharge capacities (30-50 mA Á h Á g À1 ) and longtime cycling properties.…”
