Magnesium is considered a promising orthopedic implant material due to its excellent biocompatibility and biodegradability. However, its rapid degradation and the associated corrosive byproducts can trigger inflammatory responses, limiting clinical application. To address this issue, a self-healing Mg-based composite coating was developed, consisting of an inner layer of dicalcium phosphate dihydrate (DCPD), a middle layer of polylactic acid (PLA) containing the corrosion inhibitor phytic acid (PA), and an outer PLA layer. The dissolution of the DCPD layer releases Ca²⁺ and PO₄³⁻ ions, which react with Mg²⁺ to form a stable calcium-phosphate (Ca-P) precipitate. Simultaneously, PA molecules released from halloysite nanotubes (HNT) in the middle layer chelate with Mg²⁺ to form magnesium phytate, enhancing corrosion resistance through a synergistic mechanism. Scratch tests demonstrated that the coating effectively inhibited corrosion propagation after 8 h of immersion in 0.9 wt% NaCl solution. During immersion, the current density initially increased from 1.460 × 10 - ⁸ A·cm −2 to 8.374 × 10 −7 A·cm −2 , followed by a slight decrease to 6.338 × 10 −7 A·cm −2 , indicating a self-healing response. In vitro experiments with MC3T3-E1 cells confirmed good biocompatibility of the coated Mg. Furthermore, in a rat femoral implantation model, the coated Mg exhibited improved in vivo corrosion resistance and enhanced new bone formation, with elevated expression of osteocalcin (OCN) and osteopontin (OPN) around the implant.

Anticorrosive coatings for corrosion protection on aluminum alloy remain challenges in high protection efficiency and stability with facile design. Here, a stable superhydrophobic film is successfully prepared on 5052 aluminum alloy (AA5052) by electrodeposition to enhance its corrosion resistance in 3.5 wt% NaCl solution. The contact angle reaches 157° at the electrodeposition voltage of 10 V. Electrochemical tests confirm that it can serve as a highly effective and stable coating for corrosion protection with an inhibition efficiency ( η ) of 99.1%. The charge transfer resistance of the coated Al alloy increases remarkably from 8.955 kΩ cm 2 to 366.1 kΩ cm 2 . Besides, the superhydrophobic surface shows good stability when it is exposed to air and NaCl solution for a long time. After immersion for 12 days in 3.5 wt% NaCl solution, the superhydrophobic coating still exhibits a low corrosion current density of 3.309 × 10 -7 A/cm 2 . The synergy effects of the superhydrophobicity and the Ce 3+ endow the coating with remarkably enhancing corrosion resistance. This facile strategy can provide new ideas for designing highly effective and stable anti-corrosion coatings on aluminum alloy.

The continuous development of the global marine industry has posed significant challenges to sustainable development due to corrosion in marine engineering structures. While rust converters are regarded as cost-effective solutions for corrosion mitigation, existing technological advancements fail to meet the heightened demands of contemporary marine engineering practices. To address these limitations, an MXene–phytic acid–gallic acid (M–P–G) hybrid composite was synthesized by integrating two-dimensional nanomaterial Ti3C2Tx with organic acids (gallic acid and phytic acid). This composite achieved synergistic enhancement in both rust-conversion capability and corrosion inhibition performance. Experimental results demonstrated that the M–P–G composite with a mass fraction of 1.0 wt % formed a dense rust-conversion layer on substrates, significantly improving protective performance. The M–P–G/epoxy (EP) coating exhibited an impedance modulus of 1.51 × 109 Ω cm2, surpassing conventional coatings by 2 orders of magnitude. Furthermore, through density functional theory calculations combined with scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Fourier transform infrared analyses, a corrosion protection mechanism was proposed. This mechanism elucidated the differential conversion capacities of the organic acids toward diverse corrosion products, providing critical insights for the rational design and evaluation of next-generation rust-conversion and anticorrosion materials.

Liquid phase exfoliation (LPE) method has great potential for the large-scale production of graphene due to its simplicity, scalability, and low cost. In this work, fulvic acid (FA) was chosen to assist the exfoliation of graphite into graphene for the first time via sonication in aqueous medium. The concentration of obtained graphene dispersion can reach 0.63 ± 0.04 mg mL −1 . The graphene flakes mostly consisted of 1–5 layers with sizes range in submicron to micron and few defects in the basal-plane. The π–π interaction between graphene and FA, along with the electrostatic repulsion between negatively charged FA, played a major role in stabilization of the graphene dispersion. By adjusting the pH of graphene dispersion to 14, the nanosheets of graphene came to flocculation . The formed graphene slurry is favorable for storage and transportation due to the greatly decreased volume. The annealed coating of FA-graphene on aluminum sheets was used as corrosion inhibitor for aluminum in 0.5 M H 2 SO 4 and 0.6 M NaCl solutions, with inhibition efficiencies of up to 85.5% and 99.4%, respectively. This shows that as-prepared graphene has great potential applications in the anti-corrosion of aluminum.

Copper has extensive industrial applications. However, the susceptibility to corrosion makes it vulnerable in harsh environments. Bioinspired coating presents a novel approach to address copper corrosion. Bioinspired from lotus leaves and pitcher plants, this research endeavors to create superhydrophobic and ferrofluid-infused surfaces (FIS) on copper substrate. Firstly, a one-step electrodeposition method is employed to fabricate superhydrophobic surface on copper. Secondly, Fe 3 O 4 nanoparticles are sequentially modified with dopamine hydrochloride and dodecanethiol to endow surface hydrophobicity. Then, the modified Fe 3 O 4 is dispersed in oil to create a magnetic fluid, which is finally infused onto the superhydrophobic matrix, forming the FIS coating. Electrochemical testing confirms the high protective effect of the bio-inspired superhydrophobic and magnetic fluid composite coating against corrosion. The FIS coating exhibits a prominent low-frequency impedance modulus (7.73 × 10 6 Ω·cm²) even after immersion in NaCl solution for 60 d. Furthermore, the coating demonstrates an outstanding magnetic-driven self-healing capability, as evidenced by the minimal decrease in the |Z| 0.01 Hz value (remaining as high as 10 9 Ω·cm²) even after undergoing six cycles of scratching and self-healing process. This corrosion resistance can be attributed to the combined effects of the accommodating effect of superhydrophobic matrix and the self-healing property of the magnetic fluid under the magnetic field. This dually bio-inspired coating technology offers significant advantages for copper applications in harsh environments.

The conventional slippery liquid-infused porous surfaces (SLIPSs) provide relatively limited corrosion protection and self-healing performance for AZ31 Mg alloys. To this end, 8-hydroxyquinoline (8-HQ) was incorporated into a zirconium-based metal–organic framework UiO-66 through coordination (8-HQ@UiO-66), which was then dispersed into silicone oil to fabricate nanoparticle-enhanced-SLIPSs (8-HQ@UiO-66-SLIPSs). Especially, the influences of 8-HQ@UiO-66 concentration on the surface morphology, surface hydrophobicity, and corrosion resistance were studied. It was found that the surface hydrophobicity first increased and then decreased with increasing concentration, showing the highest water contact angle of 121.2° at a concentration of 1 mg mL–1 (8-HQ@UiO-66-SLIPS-1). This was attributed to the development of well-constructed hierarchical micro/nanostructures. Moreover, it also exhibited the best anticorrosion property, with the lowest corrosion current density of 1.24 × 10–10 A cm–2 and the highest impedance modulus of 9.88 × 108 Ω cm2 at 0.01 Hz, primarily associated with the synergistic interaction of 8-HQ and UiO-66. Further, the self-healing performance was evaluated using the scanning vibration electrode technique (SVET), verifying the superior self-healing performance of 8-HQ@UiO-66-SLIPS-1. Hence, the nanoparticle-enhanced-SLIPSs exhibit considerable potential in the corrosion protection of Mg alloys, thereby accelerating their extensive applications in industry.

A superhydrophobic composite coating was facilely constructed based on MOF (ZIF-8) nanoparticles and organic resin. Hydrophilic ZIF-8 nanoparticles with hydroxyl group were firstly prepared in aqueous media at room temperature, and then modified with low surface energy perfluorooctyltriethoxysilane (POTS) through hydrolytic condensation to give a superhydrophobic paint. Additionally, epoxy resin (EP) was innovatively introduced as adhesive layer to improve the robustness and adhesive force of the superhydrophobic coating. The as-prepared ZIF-8/POTS/EP composite coating showed high water-repellency (water contact angle = 168.2°), mechanical and chemical robustness, and durability that it could maintain the superhydrophobicity after weathering in air for 300 days or immersing in 3.5 wt% NaCl aqueous solution for 60 days. The superhydrophobic composite coating also possessed excellent performance in self-cleaning, corrosion resistance, anti-icing and loading-increasing. Noteworthily, for the corrosion resistance, the ZIF-8/POTS/EP coating could increase the impedance modulus (at 0.01 Hz) of Q235 steel by about 7 orders of magnitude after immersion in 3.5 wt% NaCl aqueous solution for 7 days. We believe that this work can not only promote the effortless and large-scale preparation of superhydrophobic surface and their practical applications in future, but also provide a novel way for applying MOF materials into more fields.

A giant molecule containing hydrophobic polyhedral oligomeric silsesquioxane (POSS) and protonic acid-doped tetraaniline (ATA) was designed and synthesized via isocyanate–amine reactions. This flower-like filler exhibits redox activity and high specific capacitance (280 F g −1 ), making it feasible for corrosion protective applications. Electrochemical impedance spectroscopy, local electrochemical impedance spectroscopy, and salt spray tests were performed to evaluate the effect of POSS–ATA on the corrosion inhibition performance of the coating. This giant molecule expands the scope of conducting polymers for the active corrosion inhibition of metallic substrates and provides a platform for studying the multi-responsive self-assembly behaviour of conducting polymers.

Herein, a superhydrophobic surface was designed and fabricated based on the “lotus effect” construction mechanism. The zeolitic imidazolate framework (ZIF-90) micro-nanoparticles were initially synthesized via a one-pot method, combined with long-chain stearic acid (STA), and subsequently embedded in polyvinyl butyral (PVB) to form a superhydrophobic surface at room temperature. The superhydrophobic surface demonstrated mechanical stability and retained its superhydrophobicity with a water contact angle (CA) greater than 150°, even at a wear distance of 400 cm. The composite coating formed by applying this superhydrophobic surface to magnesium (Mg) alloy exhibited a high corrosion potential (Ecorr = −0.86 V) and a low corrosion current density (icorr = 3.66 × 10–12 A·cm–2) compared to the uncoated Mg substrate (Ecorr = −1.53 V, icorr = 1.14 × 10–4 A·cm–2), indicating that the coating effectively enhances the corrosion resistance of the substrate. Notably, the superhydrophobic composite coating demonstrated corrosion resistance durability with a high charge transfer resistance (Rct = 5.12 × 109 Ω·cm2) after 5 days of immersion in 3.5 wt % NaCl aqueous solution. In addition, the as-prepared superhydrophobic surface also displayed excellent performance in self-cleaning and anti-icing. We believe that this work can facilitate the application of ZIFs on superhydrophobic surfaces and provide a new approach for metal corrosion protection.

Magnesium (Mg) alloys are susceptible to being attacked by corrosive ions in practical application environments, which limits their widespread application as the most promising engineering material. Herein, the superhydrophobic composite coating PVB/STA/ZIF-8@SiO 2 (PSZS) has been designed on the surface of Mg alloy by using a drop coating method to improve its corrosion resistance. In this study, we provide an approachable decoration strategy for hydrophobic and hierarchical modification of zeolite imidazolate frameworks (ZIF-8) with stearic acid (STA) and SiO 2 , and combined with polyvinyl butyral (PVB) to form a composite coating with excellent performance on the substrate surface. Notably, the PSZS composite coating exhibited superhydrophobic and the contact angle is greater than 150° after 300 cm of mechanical friction. The electrochemical testing of the PSZS composite coating indicated that it greatly protected the Mg alloys from corrosion. Moreover, the PSZS coating displayed highly effective corrosion resistance even after being immersed in 3.5 wt% NaCl aqueous solution for 7 days. Overall, the PSZS composite coating with the advantages of corrosion resistance, corrosion durability, superhydrophobic, abrasion resistance and simple preparation process broadens the horizons of Mg alloy corrosion resistance research.

Marine biological fouling has a serious impact on artificial facilities, and traditional antifouling coatings are not beneficial to green development, which lead to the urgent to develop green strategies that can effectively prevent fouling. In this study, an innovative confluence of physical and biological approaches was employed to mitigate the harm caused by biofouling on a material substrate. Firstly, a hierarchical microstructured morphology was prepared on an aluminum surface by reactive ion etching and characterised. The antibacterial peptide, A-2S, was surface modified with dopamine as a coupling agent to produce a physico-biological synergistic antifouling surface. X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, and electrochemical experiments were then used to analyse the binding effect and corrosion resistance performance. A-2S was successfully modified on the sample surface and exhibited good corrosion resistance with a corrosion inhibition efficiency of 86.57 %. Compared to a bare aluminum plate, the microstructure surface has a certain inhibitory effect on fouling organisms, and the antifouling performance decreases over time. In contrast, the antimicrobial peptide synergistic surfaces demonstrated superior durable antifouling performance. Compared with the 50 % of the antifouling performance on the microstructure surface, the synergistic surface has a unique contact point effect of the microstructure and excellent antibacterial and bactericidal properties of antimicrobial peptides, resulting in a surface antifouling performance of over 80 %. The synergistic modification method enhanced the corrosion resistance of the material and reduced the adhesion of fouling organisms, mitigating the harm caused by biofouling on the marine equipment substrate.

Magnesium is a promising anode material . However, the magnesium anode will quickly react with the electrolyte to form an ion-insulated passivation film, resulting in voltage hysteresis. Because the magnesium anode is easily corroded, it leads to a decrease in its electrochemical performance. In this paper, the anode of the magnesium battery was modified by ZIF-8 coating. The ZIF-8 coating can largely prevent contact between water in the solution and the surface of the magnesium anode, which can inhibit the passivation of the magnesium anode. The voltage hysteresis time is significantly reduced from 4 s before modification to 0.3 s, which also effectively reduces the resistance of the battery. Compared with the unmodified magnesium battery, the modified magnesium battery has a larger initial voltage and a longer discharge platform. The anode utilization rate is doubled compared with that before modification, and the specific energy density is also greatly improved. The ZIF-8 coating with porous network structure and hydrophobicity can slow down the infiltration of corrosive substances to some degree, prolong its transmission path, and provide better protection for the magnesium anode.
