Synthesis and characterization of polyaniline/graphene nanocomposite coating on copper condenser tubes of Ramin Power Plant, Ahvaz

One of the common methods used in the field of protection is the application of nano-protective coatings made of paints, organic resins, plastics or noble metal films on equipment. In this research, the polyaniline-graphene nanocomposite coating was electrochemically coated on a copper electrode by cyclic voltammetry, and the corrosion resistance of copper substrates covered with polyaniline-graphene nanocomposite was measured using potentiodynamic polarization and electrochemical impedance spectroscopy methods in ۵۰۰۰ ppm of NaCl aqueous solution at room temperature. The results showed that the corrosion potentials in the presence of polyaniline-graphene nanocomposite were transferred to the anodic regions and electrochemical measurements of this coating protected copper against corrosion and protected up to ۹۸% of copper in the condenser tubes of Ramin Power Plant.
