dc.description.abstractConductive polymers have an important potential against the corrosion applications because they arehighly resistant to chemicals besides they have homogeneous coating properties and transport metals tomore noble regions. However, the major disadvantage of conductive polymers such as polypyrrole (PPy)is their low mechanical strength. In this study, the doping effect of MoS2into the PPy coatings by theelectropolymerization of polypyrrole (PPy) and exfoliated MoS2on the corrosion of brass was investi-gated. The corrosion protection of these coatings were determined by measuring the corrosion rates withTafel polarization method in 0.1 M H2SO4media. PPy and MoS2doped PPy (MoS2@PPy) coatings weresuccessfully obtained by the use of chronoamperometry technique in 0.2 M H2C2O4solutions with 0.2 Mpyrrole and various concentrations of MoS2. It was observed that MoS2@PPy coatings were homoge-neously coated without and with all MoS2concentrations on the metal surface and well adhered to thebrass surface, but MoS2@PPy coating with 25 ppm MoS2showed the best corrosion protection. Thesurface and chemical characterizations of the coatings were performed by SEM-EDS
