Abstarct: In this thesis, electropolymerization of Pyrrole has been studied in the presence of anionic surfactant (SDS) in aqueuos media. The rate of polymer grouth and its properties depended to electropolymerization conditions such as electrosynthesis techniques, substrates, electrolyes, monomer concentration and also the presence of material stabilizers. Electrochemical study and morphology of polypyrrole film show that polymers obtained from poentiostatic technique have very well electroactivity and hemogenity than galvanostatic technique. cyclic voltammograms of polypyrrole on the Pt electrod, demonsterated a lower background current and the better symmetrical peaks comparing with Au and GC electrodes. Nitrate electrolyte had the best efficiency for electropolymerization. The results show that the rate of electropolymerization increases in presence of SDS and then yields the electroactive, adhesive and unic polymer films. Also, we find that the optimized concenteration of monomer decreases in presence of SDS. Anodic peak and activation energy polymerization, approach to low quatities in presence of SDS. Scaning electron microscopy images show that PPy films take a small size and extended surface particles with better diffusity wich affected by stabilizers. Models of polymer grouth is flowers-like in absence of SDS and it is string-like in SDS media.
