Two synthesized polymers were studied as potential corrosion inhibitors for N80 Steel in a sweet corrosive environment. Poly-2-(methacryloyloxy)ethyltrimethyl ammonium chloride (PDMC), or P1, and poly-2-(methacryloyloxy)ethyltrimethyl ammonium chloride- co - N -vinyl-2-pyrrolidone P(DMC- co -NVP), or P2, were investigated using electrochemical impedance spectroscopy, polarization technique, scanning electrochemical microscopy (SECM), scanning Kelvin probe (SKP), and scanning vibrating electrode technique (SVET). The surface was examined using contact angle, scanning electron microscopy, and atomic force microscopy methods. Analyses of electrochemical and polarization techniques revealed a PDMC polymer with a better inhibition efficiency. The SECM, SKP, and SVET methods showed the insulating ability of the polymers that formed a protective coating on the metal surface.
