In this study, corrosion protection composite films composed of polypyrrole (formed from the electropolymerization of pyrrol monomer) and Vulcan XC-72, labeled as PPy-C, were deposited on SS-304 substrates by EPD using an asymmetric AC signal (AAC) in acetone and acetone:methanol solutions. Prior to deposition, Vulcan powders were functionalized in order to create functional groups that develop a negative surface charge. Under the applied electric field, both pyrrole monomer and carbon colloidal particles migrated simultaneously toward the SS anode surface to create the corrosion protection PPy-C coatings. The effect of applied voltages (50, 70, 90 and 120 V) and deposition time (2, 6, 10 and 15 min) on the film characteristics was evaluated. The coatings were analyzed by SEM and the results showed improved characteristics of the films deposited by AAC, in terms of homogeneity and porosity …
