This work reports the electrochemical synthesis of polypyrrole (PPy)films onto silicon (Si) support in an organic solution usingpotentiostatic mode of electrodeposition. Electrodeposition of PPy wasconducted under oxidative conditions; the current transient curve,taken at constant potential of 1.1 V, was discussed. The microstructureof the polypyrrole (PPy) films obtained is examined by SEM andAFM.
