Surface modification of mild steel by a self-assembled cetyl-trimethyl ammonium bromide (CTAB) monolayer: Evaluation of its corrosion protection property

- We modified the hydrophilic steel substrate into hydrophobic by using CTAB SAM.
- Proposed CTAB inhibition efficiency in different pH solution.
- SAM reduced corrosion rate by 4 times in 1 M HCl compared to bare steel.
- In 3.5% NaCl corrosion rate reduced by 1.5 times compared to bare steel.
