“…Mefp-1 adsorbed on carbon steel forms small aggregates as reported in our previous paper, however, the aggregates in the Mefp-1 and ceria composite film are larger than those in the adsorbed Mefp-1 film, despite a higher concentration of Mefp-1 in the solution in the previous study. 3 A densely packed Mefp-1 and ceria composite film fully covering the surface should give a certain corrosion protection for carbon steel, and some Fe dissolution during initial exposure may lead to enhanced complex formation in the surface layer and consequently increased corrosion protection, which indeed is verified by the electrochemical measurements (next section).…”

Thin composite films of the mussel adhesive proteins (Mefp-1) and ceria nanoparticles were deposited on substrate surfaces by alternating immersions. The film formation was studied by quartz crystal microbalance with dissipation (QCM-D) monitoring. Both the changes in frequency and dissipation recorded by QCM-D demonstrate buildup of a composite film of Mefp-1 and nanoceria. Micro-and nanostructure and composition of the film on carbon steel were characterized by optical and atomic force microscopy (AFM), electron probe micro analyzer (EPMA) and confocal Raman microspectroscopy (CRM). Optical and EPMA observations of the film show micron-sized aggregates and AFM imaging of the compact and smooth areas reveal the nanostructure. EPMA elemental mapping indicates that the micron-sized aggregates are rich in ceria and Mefp-1, whereas CRM analysis shows the presence of Mefp-1-Fe complexes in the film. Corrosion protection of the composite film on carbon steel was investigated by electrochemical impedance spectroscopy and potentiodynamic polarization measurements in NaCl solution, and compared with Mefp-1 added in the solution as an inhibitor. The measurements show that the composite film provides a higher corrosion resistance compared with Mefp-1 added as inhibitor. The corrosion resistance increases with exposure time and approaches a high level. Corrosion inhibitors are widely used to control corrosion of metallic materials that causes huge economic cost to our society, and even catastrophes due to unexpected failure of metallic constructions and devices. In the past decade, extensive efforts have been devoted to developing new "green" corrosion inhibitors to replace traditional ones that are harmful to human health and ecological systems.1 Filmforming inhibitors based on organic substances that are more "green" for human and environment have attracted considerable attention in recent years. For example, a mussel adhesive protein (MAP), derived from marine mussel Mytilus edulis, has shown a certain inhibition effect on stainless steel.2 In our previous study, Mefp-1, the type of MAP that has been most studied, was shown to exhibit interesting inhibiting properties on carbon steel in NaCl solutions. However, the inhibition efficiency of Mefp-1 is limited since the adsorbed film is not sufficiently compact, and this is particularly a problem for the initial period during which Mefp-1 does not give a significant inhibition effect. 3The adhesive and cohesive properties of MAP are generally attributed to the high content of di-hydroxyphenylalanine (DOPA), 4 which has been reported to form complexes with metal ions 5,6 and metal oxides. Waite et al. have concluded that the DOPA moiety in the proteins serves two important roles in MAP adhesion to many surfacesthe formation of interfacial complexes promoting chemisorption and cross-links. 8,9 In another study of adsorption and corrosion protection of polydopamine based surface films on aluminum alloys, it was concluded that these self-assembled surface films can provide a c...

Several proteins found in the adhesive system of the common blue mussel Mytilus edulis have chemical properties which may enable them to inhibit the flash rusting of steels. In this work, Mytilus edulis foot proteins (MAPs) 1, 3, and 5 were isolated and applied to a high strength low alloy steel in a number of buffer systems containing varying amounts of borate, acetate, and phosphate at pH 5.5-7.0. Treated steel samples were then monitored in an exposure chamber at 40 • C and 100% relative humidity for 7 days. The MAP treatments were also evaluated using electrochemical impedance spectroscopy (EIS). The effect of enzymatic crosslinking of the applied proteins using mushroom tyrosinase was also investigated. Steel samples treated with MAP-1 did not inhibit corrosion when the protein was dissolved in deionized water, and the effect of MAP-1 dissolved in buffers containing acetate was not significantly different from control samples. However, when dissolved in 0.05 M phosphate buffer solution at pH 5.5, MAP-3 and MAP-5 were capable of significantly increasing the time to corrosion and significantly reducing the mass loss of the steel coupons in the exposure chamber compared with controls when treated with enzyme. The performance of the crosslinked MAP-5 was similar to a commercial flash rust inhibitor applied at the same mass concentration as the protein, suggesting that MAP-5 and similar proteins or polymers may be capable of inhibiting corrosion. In the past two decades, mussel adhesive proteins (MAPs) from the common blue mussel Mytilus edulis (L) have been the subject of a few investigations into their potential use as corrosion inhibitors, with the hope being that the properties of these biomolecules could be replicated in new formulations of environmentally-friendly corrosion inhibitors. [1][2][3][4] MAPs have a number of unique properties, most of which rely to some extent on the presence of the catecholic amino acid L-3, 4 dihydroxyphenylalanine (DOPA). Like other catechols, DOPA can form strong complexes with many metals, particularly Fe(III).5 These metal-catechol complexes can form either in solution, or on a metal oxide surface.6 It has been shown that in some cases the formation of stable organometallic complexes on a metal surface can inhibit corrosion by preventing the dissolution of the oxide layer to which it is adsorbed.7 Previous investigations have indicated that DOPA-containing proteins are capable of inhibiting corrosion to various degrees on some metals. 1,[8][9][10][11][12][13] In addition to this, DOPA can participate in crosslinking reactions as a result of chemical or enzymatic oxidation. When oxidized, DOPA forms a quinone-intermediate, which can in turn react further with catechol groups or nucleophiles present elsewhere in the protein to form a crosslinked protein.14,15 Previous findings by Hansen et al. 16 demonstrated that enzymatic cross-linking of adsorbed MAP-1 protein resulted in thickening of the protein film, whereas others have reported a compression of the adsorbed prot...

Green polymers as corrosion inhibitors are gradually used to protect metal in solution environment. A polyaspartic acid threonine derivative (PASP-Thr) was synthesized and its structure was characterized by Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance. The corrosion inhibition effect of polyaspartic acid (PASP) and PASP-Thr on carbon steel in simulated cooling water was investigated by weight loss tests and electrochemical measurements. Experimental results show PASP-Thr as a mixedtype inhibitor exhibits higher corrosion inhibition efficiency than PASP, and the inhibition efficiency of PASP-Thr reached 93.06% at the dosage was 200 mg L −1 . The carbon steel surface in different situations was analyzed using atomic force microscope, scanning electronic microscope/energy dispersive X-ray, and FTIR, demonstrates the formation of a protective film on carbon steel surface. The inhibition effect of PASP-Thr was primarily attributed to the protective film formed on steel surface by physical and chemical adsorption. Moreover, quantum chemical calculation elaborated the relationship between the inhibition efficiency and the PASP-Thr molecular structure.
