POLYPYRROLE Usage And Synthesis

Uses

Polypyrrole is a reactant used to synthesize an eco-friendly cellulose-derived carbon aerogels.

Uses

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

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

Uses

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.

Definition

ChEBI: 1H-pyrrole is a tautomer of pyrrole that has the double bonds at positions 2 and 4. It is a pyrrole and a secondary amine. It is a tautomer of a 2H-pyrrole and a 3H-pyrrole.

General Description

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 ?-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,
