Self-assembled monolayers corrosion inhibitors

In this work, several molecular coverages are considered, and a dense, self-assembled monolayer (SAM) of inhibitor is modeled. The other studies are also interesling for some aspects In Ref. [45], both the metal and oxidized surfaces are considered when studying the mole-cule/surface interaction. This is interesting because for metals protected by a passive film corrosion (e.g., localized corrosion) may occur also in electrochemical conditions where the passive oxide film is present on the metal surface. We also note that in Ref. [46], the solvent was included in the study of the interaction. 

Nanoparticle-based corrosion inhibitors and self-assembled monolayers... 

Key words corrosion inhibitors, functionalized nanoparticles, self-assembled monolayers, surface-modified nanoparticles, nanofilms, release-on-demand inhibitors. 

Nanostractured materials are good carriers for organic corrosion inhibitors, which can be smartly released on demand, thereby improving the longevity of the corrosion-protected stmctures. Self-assembled monolayers formed on a metal oxide/metal have potential apphcation in corrosion inhibition as they react spontaneously on the metal surface and form compact and stable films, which are noted for their hydrophobicity. 

The STM imaging of self-assembly of inorganic anions was reported by Ge et aL They have reported an STM image of a monolayer a-SiWi204o on Ag(lll) surface. Such observation are veiy important because of polyoxomctalatcs function as superacids, corrosion inhibitors, electron transfer reagents, catalysts and photochemical oxidants. 

Laibinis and Whitesides reported that alkanethiols adsorbed on a copper surface form densely packed SAMs, which were found to be effective inhibitors of copper corrosion in air. ° Feng et al. reported the corrosion protection of self-assembled alkanethiol monolayer on copper in a 0.5M NaCl solution." Aramaki and co-workers reported that the maximum efficiency of the SAM of octadecanethiol for protection of corrosion of copper in 0.5 M Na2S04 solution was 80.3%." Quan et al. studied the protection ability of the SAMs of Schifif bases on copper surfaces." " ...
