Gallium-based liquid metals (GLMs) exist as atypical liquid-phase metals at and near room temperature while being electrically and thermally conductive, enabling copious applications in soft electronics and thermal management systems. Yet, solid metals are affected by interfacing with GLMs, resulting in liquid metal embrittlement and device failure. To avert this issue, mechanically durable and electrically tunable diffusion barriers for long-term reliable liquid metal–solid metal interfacing based on the deposition of various diamond coatings are designed and synthesized, as they feature high chemical inertness and extraordinary mechanical resistance. The diamond coatings show superlyophobicity (GLM contact angle ≥ 155°) and are nonstick toward GLMs, thereby achieving high mobility of GLM droplets (sliding angle 8–12°). The excellent barrier and anti-adhesion performance of the diamond coatings are proven in long-term experiments (3 weeks) of coated titanium alloy (Ti) samples in contact with GLMs. The electrical performance of the conductive diamond coating deposited on Ti is reliable and stable over a period of 50 h. As proof-of-concept applications a switch and a thermal management device based on liquid metals are demonstrated, signifying that coating diamond films on metals is a potent means to achieve stable integration of solid metals with GLMs.

Further exploration of MXene’s potential in self-healing materials is promising, given its exceptional surface properties and adaptability to various modifications. In this study, the surface of MXene was functionalized with 2,5-diaminobenzenesulfonic acid (2,5-DBSFA) and 1-{3-[(N-n-butyl) aminoformamido] propyl}-3-cetyl imidazolium bromide (M16) successively, resulting in the successful preparation of functionalized MXene (f-MXene). It was added as an anticorrosion and wear-resistant filler to the self-healing epoxy resin coating with dynamic disulfide bonds, and the corrosion and friction behaviors of the coating were explored. Under heating at 170 °C for 10 min, the self-healing performance of the EP coating was significantly improved, with |Z|0.01Hz increasing from 6.77 × 106 to 1.54 × 108 Ω·cm2. This significant increase indicates that functionalized MXene can act as an effective repair agent in the EP matrix, working together with dynamic disulfide bonds to promote self-healing of microcracks or damage. Moreover, the tribological test results indicate that the addition of f-MXene not only enhances the self-healing ability but also improves the coating’s tribological properties. The introduction of f-MXene into the EP coating results in improved resistance to wear and friction, in which the average coefficient of friction decreased from 0.53 to 0.33 and wear rate has decreased 53.3%. This is attributed to the excellent mechanical and chemical properties of MXene, which can improve the stress distribution of the coating and form a self-lubricating film during friction.

Acids are traditionally used in the production of environmentally-friendly cationic waterborne polyurethane dispersions. However, the effect of their conjugate bases on the final properties of waterborne polyurethanes has been rarely explored. In this study, the effect of different acids in tailoring the performance of bio-based cationic waterborne polyurethanes has been reported. Polyurethane films ranging from flexible elastomers to tough plastics can be obtained, and their properties can be simply controlled by the selection of the acids. The tunability of the hydrogen bonding strength confers the resulting polyurethane films enhanced multi-function, such as UV absorption, anticorrosion properties, and long-term antibacterial performance. These results represent a significant advancement over traditional techniques, providing a simple strategy to tailor the performance of cationic waterborne polyurethanes, and offering environmentally-friendly amino acid substitutes for commonly used acids, such as acetic acid, HCl, or glycolic acid. The methodology described here eliminates long-standing issues of PUs, such as irritating odor, corrosiveness, and air pollution.

Dispersion of graphene in solvents is of crucial importance toward its practical applications. In this study, using a water-soluble carboxylated aniline trimer derivative (CAT–) as a stabilizer, the commercial graphene can be stably dispersed in water at high concentration (>1 mg/mL) via strong π–π interaction that was proved by Raman and UV–vis spectra. Moreover, the CAT–-functionalized graphene sheets (G-CAT– hybrid) exhibited high conductivity (∼1.5 S/cm), good electroactivity and improved electrochemical stability. The addition of well-dispersed graphene into waterborne epoxy system (G-CAT–/epoxy) remarkably improved corrosion protection compared with pure waterborne epoxy coating, based on a series of electrochemical measurements performed under 3.5% NaCl solution. This significantly enhanced anticorrosion performance is mainly due to the improved water barrier properties derived from highly dispersed graphene nanosheets in the epoxy coating.

Developing a coated metal mold to avoid scuff, corrosion, and fouling in rubber vulcanization condition remains challenging. Here, a composite coating is described which combines resistance to fouling, wear, and corrosion by incorporating low surface energy tungsten disulfide (WS 2 ) into a robust cobalt (Co) matrix for wear and corrosion resistance together with antifouling. The dispersity of WS 2 in the electroplating solution is improved by combining chemical modification with mechanical milling. The addition of 2 g/L WS 2 to the electroplating bath produced a Co-WS 2 composite coating with effective tribological and anticorrosion performance in 3.5 wt.% standing NaCl solution at 25 ℃ as well as superior antifouling behavior in rubber vulcanization conducted at 160 ℃ and 9.8 Mpa.

Both superhydrophobic bulk modification and coating have inherent limitations in providing waterproofing and anti-corrosion properties for concrete. This study developed a slurry with exceptional penetration at room temperature, seamlessly integrating superhydrophobic properties with concrete’s inherent strength. After two applications of spraying, the slurry penetrates concrete blocks to a depth exceeding 10 mm. After 2 min of spraying the slurry at room temperature, the concrete exhibits hydrophobic properties, achieving superhydrophobicity after 7–9 h, with a water contact angle of 156 ± 0.5° and a sliding angle of 3 ± 0.5°. Treated concrete blocks show at least a 70 % reduction in water absorption after immersion in various solutions for 30 days. They also demonstrate strong resistance to freeze–thaw cycles, temperature shocks, electrochemical corrosion, abrasion, and UV radiation. This innovative method offers a promising approach for designing superhydrophobic concrete, thereby enhancing its practical applications in engineering.

In this research, a simple and cheap method was presented to make steel superhydrophobic. A mixture of antiformin solution and hydrogen peroxide was utilized to grow a porous structure on steel foil; the antiformin solution is much cheaper and more environmentally friendly than the use of strong acids. More interestingly, lotus-leaf-like hierarchical micro-nanostructures were formed after ultrasonic treatment. The superhydrophobic surface can be further prepared by surface modification, which could withstand sandpaper abrasion for 2.24 m under a pressure of 24.50 kPa without losing superhydrophobicity. Moreover, the as-prepared superhydrophobic surface exhibits excellent self-cleaning and anti-corrosion properties.

Here, a fluorine-free robust superhydrophobic coating was fabricated on the Al alloy substrate by a simple and low-cost approach. Embed modified TiO 2 nanoparticles onto semi-cured epoxy resin adhesive layer prominently reduces the content of low-energy materials (stearic acid) on the superhydrophobic coating. This prepared coating with hierarchical structures, re-entrant structures and low surface energy shows superhydrophobic. The superhydrophobic coating shows excellent high impalement pressure even water droplets with the velocity of 3.43 m/s. This coating also exhibits stability after different tests and noticeable enhancement of adhesive strength compared with the coating without the epoxy resin. Moreover, this coating presents enhanced durability verified by a sandpaper abrasion and decreased friction coefficient by a wear test . It moreover enabled noticeable self-cleaning property. This superhydrophobic coating also shows promising anti-corrosion property in both the corrosion solution and the salt spray compared with the Al alloy substrate. Notably, the superhydrophobic property combined with photocatalytic function prominently improves the anti-biofouling property of the Al alloy substrate due to the superhydrophobicity reducing organic and bacterial adhesion and the photocatalysis providing organic degradation and preventing bacterial adhesion. The fluorine-free robust multifunctional coating with superhydrophobic and photocatalytic properties can be applied to functionalize various solid surfaces .

There remains a great challenge to develop a switchable and feasible membrane for integrate reversible separation of oil/water mixtures. Herein, a highly-quality CAU-10-H mesh membrane with switchable superwettability was fabricated via solvothermal synthesis for on-demand oil/water separation. The CAU-10-H membrane exhibited under-liquid dual superlyophobicity due to the hierarchical micro-/nanostructures constructed by interpenetrating CAU-10-H crystals grown on the mesh. Meanwhile, the secondary growth time affecting the wetting behavior of the membrane is studied. More importantly, the membrane can achieve both immiscible oil/water separation and emulsion separation with high separation flux and high efficiency (>99.9%). Moreover, the membrane shows an excellent anti-corrosive property in various harsh environment. The present development would provide novel insights into the rational fabrication of MOF-based membranes for on-demand oil/water separation.

In this work, a versatile strategy of manipulating defective metal organic frameworks (MOFs) with the assistance of the steric hindrance effect was proposed and applied in coatings. The steric hindrance effect was utilized to construct the defective MOFs with phosphate, gluconate and phytate as examples. The defective MOFs were synthesized in an aqueous solution at room temperature, having a promising future for industrial application. Tailoring specific defects in MOFs can make molecular chains of polymer penetrate into the internal skeleton and form an interlocking structure. The interlocking effect can enhance the mechanical performance of the coating, and the corrosion inhibition performance of anions can synergistically improve the corrosion resistance of the coating. The waterborne acrylic resin (WAR) embedded with phytate-modified MOF has the highest tensile strength of 23.9 MPa, four times higher than pure WAR. Anti-corrosion test results indicated that the corrosion inhibition efficiencies of composite coatings maintained around 97% after 2 months of immersion in seawater. The structure-property relations of defect-engineered MOFs and the anti-corrosion mechanisms were elaborated in detail by both experiments and molecular dynamics simulation. This strategy has excellent environmental friendliness, reduces the cost of MOF materials, and has broad application prospects.

Magnesium and its alloys are promising biodegradable materials because of their light weight and superior mechanical properties. However, the high corrosion susceptibility of magnesium is the main obstacle that hinders the application of Mg in biomedical applications . In this article, two approaches have been employed to fabricate hybrid films of hexamethylene diamine tetrakis (methylene phosphonic acid) (HMDTMPA) and hydroxyapatite (HA) on Mg. The direct dipping method involves an immersion in a single solution containing both calcium, phosphate, and the organic compound. However, it results in poor-quality loose films, due to unstable film of monocalcium phosphate monohydrate (MCPM). The other method involves immersion in two separated solutions: Ca-P solution and HMDTMPA solution. Our results showed that the corrosion resistance was enhanced about 12-times compared with HMDTMPA film due to the formation of a stable hybrid film of dicalcium phosphate dihydrate (DCPD). The mechanism of formation of anti-corrosion DCPD was discussed on the light of SEM, EDS , FTIR , XRD and XPS.

The damage caused by marine fouling organisms to ships and underwater artificial equipment is becoming increasingly serious issue, and the prevention and control of marine biofouling has always been a research hotspot in marine coatings. Aiming at the problems of poor adhesion, long curing time and high curing temperature of low-surface energy marine antifouling coatings of organosilicon, a hydrophobic low-surface energy nano-SiO 2 /silicon acrylic resin nanocomposite coating was synthesized. The anticorrosive property of the composite coatings was analyzed by simulated seawater periodic immersion experiments. The gel permeation chromatography analysis showed that polydimethyl-siloxanes (PDMS) is involved in cross-linking reactions. The dynamic thermomechanical analysis indicated that the glass transition temperature of resin is 58 °C. The contact angle (CA) test showed that the CA of nanocomposite coating is 109.99°. All the detection results can support the excellent antifouling and anticorrosion performance of the low surface energy nanocomposite coatings.
