Description

• General description: 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]
• Application: 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]
