Using the Langmuir-Blodgett (LB) technique, stearic acid (SA) monolaye
rs were deposited onto the surface of an iron (Fe) electrode to study
the inhibition effect and the mechanism of SA in a neutral medium. Mol
ecular orientation and the number of deposited monolayers of SA were s
hown to have marked effects on inhibition of Fe corrosion. The inhibit
ion mechanism depended mainly on blocking.
