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.

A glucose biosensor was assembled using gold microelectrodes (diameter of 250 μm) coated by Single-Walled Carbon Nanotubes (SWCNTs), via the Electrophoresis Deposition Process (EPD). This nanostructured platform was successfully used to deposit the poly(pyrrole)/glucose oxidase film (PPy/GOx). The most important

A novel solid-phase microextraction (SPME) fiber coated with polypyrrole/sol-gel composite was prepared through electrochemical deposition. The composite polymer coating was prepared using a three-electrode electrochemical system and directly deposited on a stainless steel wire by applying a constant potential (1.2V
