This search investigates the corrosion inhibition properties of polyacrylic acid. The corrosion inhibition performance of carbon steel (CS) in a 1M HCl solution treated with the polyacrylic acid inhibitor was evaluated using potentiodynamic polarization measurement, Field Emission-Scanning Electron Microscopy (FE-SEM) and Energy Dispersive X-ray Spectroscopy (EDS). The findings of this study demonstrate that polyacrylic acid exhibits significant effectiveness as corrosion inhibitor for CS in Acid solution. The inhibitor acts as a mixed-type inhibitor, and its corrosion inhibition efficiency increases with higher concentrations of polyacrylic Acid concentration up to 89.9% obtained at 298 K for a 400 ppm concentration, while decreasing with increasing acid concentration.
