Perfluorinated polysiloxane hybridized with graphene oxide for corrosion inhibition of AZ31 magnesium alloy

Experimental and computational studies of graphene oxide covalently functionalized by octylamine: electrochemical stability, hydrogen evolution, and corrosion inhibition of the AZ13 Mg alloy in 3.5% NaCl

“…19 Also, the corrosion inhibition of the peruorinated polysiloxane-functionalized graphene oxide coated Mg alloy was studied by Pyo et al Their results showed excellent inhibition efficiency as compared with conventional epoxy-coated Mg alloys. 20 The corrosion inhibition of the silane-incorporated graphene oxide-coated Mg alloy was studied in 3.5% NaCl medium by Zhang et al 21 The corrosion inhibition studies of the polyvinyl alcohol functionalized graphene oxide coated with 2024 aluminum alloy in 0.2 M NaCl medium were performed by Lutkenhaus. 22 The results showed that with the increased percentage composition, the inhibition efficiency increased as well.…”

Pyridine-based functionalized graphene oxides as a new class of corrosion inhibitors for mild steel: an experimental and DFT approach

“…[11][12][13] Recently graphene derivatives have been reported as anticorrosive coating materials for marine and other corrosive environments because of their various unique properties such as high surface area, chemical resistance, thermal and electrical conductivity, enhanced mechanical strength, high level of impermeability and hydrophobicity. [14][15][16][17][18][19][20][21] It is documented in the literature that the graphene is insoluble in an aqueous medium because of the lack of functional groups and therefore they are used as anti-coating materials only. 15,16 However, graphene oxide (GO) and functionalized GOs could act as good corrosion inhibitors in the solution phase because of the presence of various oxygen (O)-containing functional groups such as hydroxyls, epoxides, carboxyl and carbonyl on their surfaces.…”

Experimental Studies of Hardness Value and Corrosion Behavior of Coated Steel Bar

“…Undeniably, with the purpose of achieving the successful application of GO (Graphene oxide) in the epoxy coating, the main issue to be settled urgently is improving dispersion of GO. One of the approaches to increase GO's dispersion into epoxy coatings is the chemical modification of GO with polymeric solubilizing groups [13,14] The use of advanced epoxy-based materials with superior properties has undergone serious developments in recent years and it is estimated to take a particular place in between versatile thermosetting systems such as nanocomposite coatings [15][16][17].Our nanocomposite will be a good coating material for corrosion resistivity either against chloride or carbonation.…”
