The high aspect ratio and unique thermal and electrical characteristics of carbon nanofiber (CNF) made it an ideal physical barrier against the penetration of corrosive ions. However, the poor compatibility of the CNF with the polymer matrix and the lack of active corrosion inhibitors are the key limitations of this nanomaterial, resulting in short-term anti-corrosion resistance. An intelligent self-healing epoxy (EP) coating, including CNF modified with a polydopamine (PDA)−La 3+ complex, was successfully fabricated to overcome these issues. Electrochemical impedance spectroscopy (EIS) evaluation implied that mild steel (MS) submerged in a 3.5 wt % NaCl solution containing the CNF− PDA−La extract had a total corrosion resistance (R T ) of 3107 Ω cm 2 after 24 h, which is much greater than the MS immersed in the blank solution (1378 Ω cm 2 ). Furthermore, the potentiodynamic polarization analysis indicated a 50% reduction in the corrosion rate (CR) of the MS soaked in the solution containing released PDA and La 3+ inhibitors compared to the blank solution. EIS and salt spray analysis were used to assess the self-healing capabilities of epoxy coatings incorporating modified CNFs. EIS assessment of scratched coatings revealed a 117% improvement in R T of the CNF−PDA−La/EP coating compared to the Blank/EP after 10 h of immersion in the saline solution. This enhancement is due to the intelligent release of PDA and La 3+ inhibitors at the scratch sites, which can mitigate MS corrosion by forming a PDA−Fe complex and the deposition of La(OH) 3 on the MS surface. The salt spray test results also exhibited the CNF−PDA−La/EP coating's superior anti-corrosion capabilities after 20 days. Hence, this research presents a logical approach for developing anti-corrosion coatings with improved nanofiller compatibility and self-healing characteristics.

“…Attempts have been made to enhance the corrosion protection properties of MXenes, and one methodology involves the formation of MXene hybrids or heterostructures. MXenes have been combined with several other materials, including carbon dots (CD) [169], graphene oxide (GO) [170], graphene [171], LDHs [172], h-BN [173], MoS 2 [174] and conducting polymers [175] to form composites or heterostructures. The addition of this second material can enhance the corrosion-protective performance of MXenes.…”

“…The chemical stability of MXenes in water has been improved by using carbon dots (CD) to functionalize Ti 3 C 2 T x MXene and form a CD-Ti 3 C 2 T x hybrid [169]. Likewise, an OH-group-modified h-BN was utilized to reduce the formation of a conducting MXene network [173]. With the addition of LDHs, Ti 3 C 2 T x MXene/Mg-Al-LDH heterostructures can be formed [172], as shown in Figure 9.…”

Emerging Layered Materials and Their Applications in the Corrosion Protection of Metals and Alloys

Metals and alloys are essential in modern society, and are used in our daily activities. However, they are prone to corrosion, with the conversion of the metal/alloy to its more thermodynamically-favored oxide/hydroxide phase. These undesirable corrosion reactions can lead to the failure of metallic components. Consequently, corrosion-protective technologies are now more important than ever, as it is essential to reduce the waste of valuable resources. In this review, we consider the role of emerging 2D materials and layered materials in the development of a corrosion protection strategy. In particular, we focus on the materials beyond graphene, and consider the role of transition metal dichalcogenides, such as MoS2, MXenes, layered double hydroxides, hexagonal boron nitride and graphitic carbon nitride in the formulation of effective and protective films and coatings. Following a short introduction to the synthesis and exfoliation of the layered materials, their role in corrosion protection is described and discussed. Finally, we discuss the future applications of these 2D materials in corrosion protection.
