Opis

Opis ogólny

Polypyrrole (PPy) is a widely used highly conductive and highly stable heterocyclic polymer. It is majorly used in electrochemical applications. It is a cost-efficient conducting polymer that has a stable oxidation and high solubility in water. It exhibits a high degree of flexibility than polyaniline and has a density that facilitates a higher capacitance per unit volume.[1][2][3][4]
PPy may be prepared by a standard electrochemical technique.[5] It may also be prepared by reacting -napthalene sulfonic acid (NSA) and ammonium peroxo-disulfate in aqueous medium.[6] The charges on the surfaces can be easily modified by doping the polymer during its synthesis.[7] Solubility and conductivity measurements of PPy doped with camphor sulfonic and dodecyl benzene sulfonic acid have been reported.[8] Lectrosensitivity and lower oxidation potential of PPy make it potentially useful for drug delivery, chemical sensors, batteries, ion selective electrodes, biosensor and biochemistry research.[9]

Zastosowanie

Conducting polymer.

Conductive additive for thermoplasitics and thermosets.

Conductive additive for thermoplastics and thermosets. Polypropylene composites constitute the polymer electrolyte membrane fuel cell (PEMFC). Addition of PPy to polypropylene composites alters its conductivity.[7][10]

PPy can be used for a variety of applications such as:

• electrode materials for sensors used in electrocardiography (ECG)[11]
• formation of electrode material for a variety of energy storage applications[12]
• encapsulation of lithium sulfide (Li₂S) as a high performance cathode material[13]

PPy is mainly used in the fabrication of a variety of electrochemical devices, which include supercapacitors,[14][15] chemical sensors,[16] dye sensitized solar cells and lithium-ion batteries.[17]
