Ionic Liquids as Corrosion Inhibitors

Poly(ionic liquid)s having coumarate counter-anions as corrosion inhibitors in acrylic UV coatings

“…8 In this regard, ionic liquids (ILs) are considered an emerging class of corrosion inhibitors which, combined with their good efficiency as CIs, demonstrate several advantages, such as their non-toxic nature, versatility of application and introduction into different coating technologies. 9 In particular, the use of polymeric versions of ILs ( poly (ionic liquids)) as CIs has attracted attention due to the fact that the polymeric version (vs. the individual IL molecule) can provide better adsorption on the surface due to the presence of multiple bonding sites that can interact with mild steel surface. 10 Additionally, the polymeric IL version can displace water molecules from the metallic surface, increasing the efficiency of the CI performance and reducing the likelihood of leaching which is a common problem associated with traditional CIs in coatings.…”

Novel ZrO2-glycine nanocomposite as eco-friendly high temperature corrosion inhibitor for mild steel in hydrochloric acid solution

“…Literature study reveals that several reports are available describing the anticorrosion effect of amino acids 5 , 6 , biopolymers 7 , 8 , plant extracts 9 , 10 , rare earth metals 11 , organic compounds such as drugs 12 , 13 , surfactants 14 , and ionic liquids 15 on metals and alloys. The main disadvantage of using plant materials as corrosion inhibitors is their instability; and readily biodegradability.…”
