Description

General description

Process up to at least 170°C in air. Process up to at least 270°C under nitrogen.Polypyrrole (PPy) is a conductive and highly stable polymer. 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.

Application

Conducting polymer.

Conductive additive for thermoplasitics and thermosets.

Packaging

Packaged in glass bottles
