Stabilization of Stearic Acid LB Monolayer Film by Addition of n-Alkylthiol

Abstract
Stability of stearic acid LB monolayer in an aqueous solution is remarkably improved by the addition of n-alkylthiol. n-Alkylthiol adsorbs strongly on gold surface and acts as anchor of the stearic acid monolayer so as not to diffuse away from the substrate.
