Applications of polymers like polypyrrole and polythiophene often require interaction with an electrolyte consisting of solvent and dissolved salt. Ionic Liquids (ILs) are pure saits, fluid at room temperature, that form charged electrolytes. Pure l-Bu-3-Me-Imidazolium PF6 (BMI PF6) a hydrophobic IL that has a wide potential window, was used to investigate the electrochemistry ofpolypyrrole. Enhanced electrochemic~l stability of polypyrrole was obtained on repetitive redox cycling with respect to the equivalent propylene carbonate electrolyte with tetrabutylammonium hexaflurophosphate (TBA PF6) electrolyte.
