Abstract

Hydrophobic and corrosion-resistant coatings on metals are of great importance for preventing molecular adsorption and ion diffusion for many applications. In this study, we provide comprehensive atomic-level picture of stearic acid (SA) adsorption on oxide-coated Al surface and its behavior when exposed to aqueous solutions at 298 K. We combined molecular dynamics simulations with experimental measurements to study anti-corrosion performance and hydrophobicity of SA layers. Three SA layers were considered ranging from disordered (0.36 ML), also obtained experimentally using drop casting method, to tightly packed self-assembled monolayers (SAM, 0.5-1.0 ML) deposited on ordered oxide-coated Al surface. Coherent picture of adsorption mode and corrosion behavior in 3.5 wt% NaCl aqueous solution was obtained by combining MD simulations and electrochemical measurements (EIS) for disordered SA layer, probing the extent of improvement in anti-corrosion performance compared to pristine Al. Tightly packed SAM (1.0 ML) successfully inhibits ion and water infiltration and exhibits the best anti-corrosion performance and hydrophobic properties. Disordered (0.36 ML) and loosely packed SAM (0.5 ML) act as diffusion barrier against ion and water at early stage of corrosion and wettability test. The present studies underlined the importance of obtaining a hierarchically structured SA layer to provide protection from corrosion.
