Designing a dual-functional Epoxy anti-corrosion Coating using DopamineLoaded Zeolitic imidazolate framework-۶۷ Decorated Layered TransitionMetal Carbides/nitrides

Corrosion of rebar in concrete structures presents a significant challenge in construction. Oneeffective method to prevent rebar corrosion involves using organic polymer coatings. Polymericsystems like epoxy resin are commonly used for their corrosion resistance, but they have certainlimitations. These can be mitigated by incorporating ۲D nanomaterials. MXene, a recent addition tothe ۲D materials family, has shown exceptional performance in various applications. However,combining MXene with polymers like epoxy resin often leads to agglomeration within the polymermatrix. A promising solution to this problem is the surface functionalization of MXene using APTEScoupling agents. Additionally, the specific surface area of MXene may not be sufficient to addressthis issue effectively. To enhance compatibility with polymer systems, MXene can be combined withporous metal-organic frameworks (MOFs). ZIF-۶۷, in particular, is notable for its high thermal andchemical stability, as well as its high porosity. For added benefits, incorporating inhibitor compoundssuch as dopamine into the MXene/ZIF-۶۷ (Z۶۷-MX) composite provides active protection againstcorrosive environments.
