Abstract
In this study, chitosan-montmorillonite nanocomposites were prepared by dispersing inorganic nanolayers of clay in an organic polymer matrix via direct melt intercalation. Characterizations were performed using different methods, i.e., FTIR, NMR, SEM and AFM. This nanocomposite was used as a corrosion inhibitor. The anti-corrosion behavior of the nanocomposite on mild steel was investigated by electrochemical measurements such as electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) in hydrochloric solution acid. The results indicated that nanocomposite inhibits mild steel corrosion in 1.0 M HCl. The PDP results showed that chitosan-montmorillonite nanocomposites act as mixed-type inhibitors.
