General description

Polypyrrole (PPy) is a conductive and highly stable polymer, doped with proprietary organic acids. It may be prepared by 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.

Polypyrrole(PPy) is a π-conjugated conductive polymer that can be electrochemically synthesized and deposited on a variety of surfaces. The deposited PPy can be used in a wide range of sensor based applications due to the following properties:
• Ion exchange capacity.
• Electrochromic effects.
• Redox activity.
• Corrosion resistant.
• Catalytic activity.


Conducting polymers may be used in electronics, chemical sensors.

PPy can be used in the development of devices including:
• conductive sensors for quality monitoring
• blended with nanotubes for supercapacitors
• nanowire actuators
• biosensors for drug delivery
• CO2 absorption materials
