Beschreibung

Allgemeine Beschreibung

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 β-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]

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.[6][7][8][9]

Anwendung

Conducting polymer.

Conductive additive for thermoplasitics and thermosets.

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,[10][11] chemical sensors,[12] dye sensitized solar cells and lithium-ion batteries.[13]
