Experimental and theoretical investigation of novel ammonium-derived dihydroxyl ionic liquid as corrosion inhibitor for mild steel in 1 M HCl: Effects of dihydroxyl and head groups

Imidazolium-Based Polymeric Ionic Liquids with Short Alkyl Chains as Green Corrosion Inhibitors for Mild Steel in 1 M HCl: Experimental and Theoretical Investigations

“…Figure illustrates the equivalent circuits to fit the EIS data, which include the film resistance ( R f ), charge-transfer resistance ( R ct ), and solution resistance ( R s ). The introduced constant phase element (CPE ct /CPE f ) enables the fitting to be more accurate, which can be verified by the small χ 2 .…”

Amphiphilic Janus Graphene Oxide Acts as a Corrosion Inhibitor to Mitigate the Corrosion Caused by a 1 M HCl Solution on Mild Steel

“…The literature has demonstrated that it is hard for unmodified GO to exhibit excellent protective performance. , The most commonly employed strategy for enhancing the corrosion inhibition performance of GO involves the incorporation of heteroatoms such as O, N, S, and P. Heteroatoms typically possess lone electron pairs, which can readily form chemical bonds with Fe atoms possessing vacant d orbitals, thereby significantly augmenting the ability of GO to absorb to metal surface . Saleh et al grafted two diaminoalkanes (diaminodecane and diaminododecane) onto GO by an epoxy ring-opening reaction to synthesize two modified graphene oxides, DAD-GO and DADD-GO.…”
