ELECTROCHEMICAL BEHAVIOUR OF POLYPYRROL /POLYETHYLENGLYCOL COMPOSITES

The electrochemical activities of polypyrrole/polyethylenglycol (Ppy/PEG) composite films are examined using cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. It is observed that the electroactivity and charge transfer kinetics are a function of the PEG con...
