Descrição geral

Polypyrrole (PPy) is a conductive and highly stable polymer. It may be prepared by a standard electrochemical technique.[1] PPy may also be prepared by reacting ß-napthalene sulfonic acid (NSA) and ammonium peroxo-disulphate in aqueous medium.[2] The charges on the surfaces can be easily modified by doping the polymer during its synthesis.[3]Solubility and conductivity measurements of PPy doped with camphor sulfonic and dodecyl benzene sulfonic acid has been reported.[4] Electrosensitivity and lower oxidation potential of PPy make it potentially useful for drug delivery, chemical sensors, batteries, ion selective electrodes, biosensor and biochemistry research.5,[5]

Aplicação

Conducting polymer.
Conductive additive for thermoplasitics and thermosets.
PPy may be used to prepare cobalt based electrocatalyst for anion exchange membrane fuel cells.[6][7][8]
