Supramolecular concepts and approaches in corrosion and biofouling prevention

Abstract

Supramolecular chemistry is one of the exciting branches of chemistry where non-covalent interactions between molecules and the ensuing supramolecular structures have been studied for various applications. The present review provides a comprehensive outlook on the applications and potentials of supramolecular chemistry in corrosion and biofouling prevention. Reported works associating supramolecular chemistry with corrosion are systematically discussed under two sections: (i) surface coatings and (ii) corrosion inhibitors that include supramolecular polymers, host-guest inclusion compounds, organic-inorganic hybrid materials, and supramolecular structures of graphene, crown ethers, self-assembled monolayers, etc. Different strategies for making antifouling surfaces based on block copolymers/gel systems, host-guest systems, and metal-organic structures are briefed. Cyclodextrin and mesoporous silica-based host-guest systems are extensively discussed, as they are the most prominent materials of current research interest. Future potentials for developments are presented. The review is expected to be beneficial to enhance supramolecular chemistry-related research and development in corrosion and biofouling prevention.

Synergistic effect of potassium iodide and sodium dodecyl sulfonate on the corrosion inhibition of carbon steel in HCl medium: a combined experimental and theoretical investigation

“…The results showed that in all cases the inhibitors can restrain both the anodic dissolution of carbon steel as well as the hydrogen evolution reaction, which may be attributed to the adsorption of inhibitor molecules on the active sites of steel substrate. 23 It is obvious that the combinations of SDS and KI, produce pronounced effects on the corrosion current density compared to those displayed by individual KI or SDS. This behavior suggests that SDS and KI have a synergistic effect in inhibiting the corrosion of carbon steel in HCl solution.…”

Environmentally Friendly Tannic Acid Multilayer Coating for Reducing Corrosion of Carbon Steel

“…31 Furthermore, this study demonstrated a new usage for corrosion inhibitors, which have been predominantly utilized as additives in corrosive media. 32,33 Although corrosion inhibitors based on jojoba oil were reported to have 100% anticorrosion efficiency (i.e., no corrosion) in a 60 min corrosion test 34 and corrosion inhibitors based on Henna leave extracts were known to improve corrosion resistance of acrylic resin, 35 to the best of our knowledge, no corrosion inhibitor can keep 100% anticorrosion efficiency for at least 1 month. The long-term corrosion resistance of TA/PEI LbL assembly likely originated from its ionic-bonding-based water stability and coordination-bonding-based surface adhesion.…”

Corrosion Barrier Coatings: Progress and Perspectives of the Chemical Route

“…The development of supramolecular chemistry has widened the scope for manufacturing smart containers by installing supramolecular nano valves into their pores [176]. The exterior of the Fe 3 O 4 @mSiO 2 nanocontainer incorporated supramolecular assemblies of hypiridynium c water soluble pillar (5)arenes, thus creating corrosion potential stimulus-responsive gates.…”
