Description

Description générale

Polypyrrole (PPy) is a conductive and highly stable polymer. It may be prepared by a standard electrochemical technique. PPy may also be prepared by reacting β-napthalene sulfonic acid (NSA) and ammonium peroxo-disulphate in aqueous medium. The charges on the surfaces can be easily modified by doping the polymer during its synthesis.Solubility and conductivity measurements of PPy doped with camphor sulfonic and dodecyl benzene sulfonic acid has been reported. 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

Polypyrrole (PPy) is a widely used heterocyclic polymer that is highly conductive and is majorly used in electrochemical applications. It is a cost efficient conducting polymer that has a stable oxidation and high solubility in water. It has a high degree of flexibility than polyaniline and has a density that facilitates a higher capacitance per unit volume.

Application

Inherently conducting polymer based additive. Loading of polypyrrole in carbon black typically 20%. Stable up to at least 300°C in air.

PPy is mainly used in the fabrication of a variety of electrochemical devices which include supercapacitors, chemical sensors, dye sensitized solar cells and lithium-ion batteries.

Conducting polymer.

Conductive additive for thermoplasitics and thermosets.
