Coatings with only passive protection cannot offer long-term anticorrosion on metals. Eco-friendly sustainable and responsive coating for active/passive corrosion protection is desirable to extend the service life of metals. Here, benzotriazole (BTA)-metal organic frameworks (Cu-MOFs, UiO-66) were embedded in silica (SiO 2 ) coating by one-step electrodeposition on copper. Combined with passive capability of MOFs and active protection of BTA inhibitor, the composite coating (BTA-MOF/ SiO 2 ) exhibited high and stable corrosion resistance, confirmed by microstructure characterizations and electrochemical tests. As a result, the as-prepared composite coating exhibited superhydrophobicity with a water contact angle of 154.2°. With loading of BTA-MOF in SiO 2 coating, the impedance modulus at 0.01 Hz increased by ∼10-fold and the corrosion current density decreased to 3.472 × 10 −9 A•cm −2 . Immersion and salt spray tests confirmed the long-term protection of the composite coating. The responsive release of BTA inhibitor endows the coating with a responsively anticorrosive behavior. The active-passive ability makes the coating a good candidate for protection on metals used in highly salty environments.

“…The remarkable compatibility harnesses the protective attributes of Ti 3 C 2 T x MXene and PANI-ES in the coating matrix. Moreover, when Ti 3 C 2 T x MXene nanosheets are integrated into coatings, they leverage their unique capability to establish stable layers, which function as a tangible barricade, proficiently impeding the diffusion of corrodents like moisture, oxygen, and chloride ions 68. The impermeable shield by Ti 3 C 2 T x MXenes bars corrodents reaching the underlying substrate, effectively stalling the onset of corrosion.…”

Corrosion, a gradual deterioration of metallic bodies, poses significant risks, along with massive monetary and material losses. Surface coatings enriched with corrosion inhibitors and nanostructural fillers play vital roles in protecting the metal substrate against the corrodents. In the present work, Ti3C2T x MXene, synthesized by selective chemical etching of an aluminum layer from the Ti3AlC2 MAX phase, is used as a platform material to interfacially grow the polyaniline (emeraldine salt form; PANI-ES) via oxidative polymerization of aniline for preparing the Ti3C2T x -PANI-ES nanocomposites. The reinforcement of the epoxy matrix via multiple interactions with ample nitrogen and oxygen functionalities of Ti3C2T x -PANI-ES nanocomposites enhanced the structural compactness, elastic modulus, and hardness of the resultant epoxy coatings. The Ti3C2T x -PANI-ES nanocomposites as a protective filler to the epoxy coating improved the corrosion inhibition properties in the accelerated corrosive environment (3.5% saline solution). The Ti3C2T x -PANI-ES increased the total electrochemical impedance of epoxy coating by 11 orders of magnitude, which is further corroborated by the protection of the underlying steel substrate under continuous exposure to salty fog. The Ti3C2T x MXene as a structural barrier impedes the diffusion of corrodents, and the electroactive PANI-ES minimizes the galvanic events by trapping the electrons released during the anodic oxidation of iron and forms a passive layer to protect the underlying mild steel. Therefore, Ti3C2T x -PANI-ES nanocomposites can be promising materials for corrosion inhibition applications.

The development of nanomaterials is crucial to upgrading of modern industry. MXene nanosheets have attracted significant attention due to their superb resistance to permeation, diverse surface chemical properties, impressive mechanical properties, and metal‐like electrical and thermal conductivity, etc., providing unique advantages in various technical fields. When MXene nanosheets are combined with polymers to form functional coatings, their applications span multiple fields, including anticorrosion, wear resistance, flame‐retardancy, electromagnetic interference (EMI) shielding, and de‐icing. This review, in conjunction with MXene's barrier property, lubricity, thermal stability, conductivity, and photothermal conversion property, discusses in detail the various applications of MXene‐based polymer coatings. Additionally, it examines the dispersion and interaction of MXene within polymer coatings and the role of functionalized MXene in polymers. Finally, based on the current research status and emerging needs, the development challenges and future research opportunities of MXene‐based polymer coatings in a targeted manner are discussed. This review aims to summarize the existing research results and put forward an objective and fair point of view, providing a constructive reference for upgrading modern nanofunctional polymer coatings.
