Relationship between chain length, disorder, and resistivity in polypyrrole films

Article Abstract:

The effects of the polymerization temperature and of voltammetric cycling on the chain length and the resistivity of polypyrrole films are investigated. As the electropolymerization of conjugated systems in contrast to normal polymerization reactions is a fully activated process, the generation of the different types of polypyrrole depends on experimental parameters such as temperature or formation potentials.

Conductive polypyrrole via enzyme catalysis

Article Abstract:

Laccase catalyzes the polymerization of pyrrole into a conducting polymer using dioxygen as the terminal oxidant. The charge transport properties of the resulting polymers, both with and without 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) as the counteranion, are compared to those of other conducting materials including polypyrrole prepared electrochemically or chemically.

Influence of acidity on the formation of polypyrrole and the multipathway mechanism

Article Abstract:

In a solution of high acidity, the application of a low potential to the electrolysis passivates the electrode. This is the result of the formation of nonconductive PPy(III) with a low level of conjugation. The volummetric investigation of PPy showed two clear sharp oxidation waves.
