Chemical synthesis of highly electrically conductive polymers by control of oxidation potential

Removal of fluoride ions from aqueous solution by conducting polypyrrole

“…The scanning electron microscopic (SEM) image ( Fig. S2a and b) of PPyCl, is also characteristic of the polymer and which resembles that of reported earlier [26].…”

Application of chemically synthesized conducting polymer-polypyrrole as a carbon dioxide gas sensor

“…Angeli et al [14] first reported the chemical polymerization of pyrrole (Py) monomers in 1916. Miyata and co-workers [15,16] investigated typical chemical synthesis of PPy using anhydrous FeCl 3 as an oxidant/dopant in various solvents. They found that while methanol appeared to be the best solvent for optimal conductivity and morphology, the equilibrium redox potential of the solution controllable via the relative concentration of monomers and oxidants and via addition of FeCl 3 was a more important determinant of polymer quality.…”

Highly Conductive Polypyrrole Copolymers?

“…It was published by a Japanese group in the 1990s. [4] We have found that this high value is reproducible under the given reaction conditions, and we believe, by comparison with literature from other groups and reproduction of their results, that the synthetic method of Whang et al [4] (acetonitrile/methanol 86:14 vol.-%, low reaction temperature, FeCl 3 as oxidant, and exclusion of oxygen) gives state-of-the-art material with the highest conductivity. In the following, we report our experience and findings in the attempt to reproduce the data given in ref.…”
