The rapid rise in demand for environmentally friendly technologies, and the shift toward a sustainable, fluorine/silane-free approach is critical for driving groundbreaking advancements in environmental remediation solutions. This study reports the synthesis and comprehensive characterization of a multifunctional foam featuring exceptional superhydrophobic and superoleophilic properties, tailored for advanced anti-corrosion, self-cleaning, and oil-water separation applications. Utilizing chicken eggshell waste, we developed a sustainable, fluorine/silane-free coating by first synthesizing functionalized calcium carbonate (FCC) with a cactus-like micro/nanostructure. This FCC exhibited a core-shell structure with a crystalline core and an amorphous calcium carbonate shell. We then fabricated the r-AC-FCC-coated foams using dip-coating and reduction techniques. The r-AC-FCC coating demonstrated outstanding anti-corrosion performance, particularly in saline conditions, with an inhibition efficiency surpassing 80 % and significant corrosion rate reductions in acidic and alkaline environments. The foam achieved a remarkable oil-water separation efficiency of 97 %, showcasing an impressive oil adsorption capacity of 12-65 g/g. Enhanced mechanical properties of r-AC-FCC coated foam were noted, with compressive strength and modulus of elasticity improved by 69 % and 119 %, respectively. The foam also exhibited superior self-cleaning performance and maintained high efficacy over multiple reuse cycles. Biocompatibility tests indicated effective oily wastewater treatment, significantly improving mung bean germination rates. This innovative foam leverages the optimal synergy between surface roughness and energy, underpinned by FCC's hierarchical nanostructures and robust r-AC anchoring, offering a powerful, sustainable solution for environmental remediation and material protection.

Coated electromagnetic interference (EMI) shielding textiles with conductive coatings could efficiently reflect and absorb electromagnetic waves (EMWs), and are widely used in various applications, including consumer electronics, medical technology, and the automotive industry. However, the accumulation of heat during operation may pose a fire risk, potentially damaging the coating and compromising its ability to provide effective electromagnetic protection under fire conditions. To address this issue, we designed a multi-layer nano coating incorporating flame retardants and conductive nanofillers, specifically AgNWs, MXene, and graphene. This coating could achieve sustainable EMI shielding capabilities under fire conditions. Especially, the A1-M1.5-G0.5 exhibited excellent flame retardancy, reducing the total heat release (THR) value from 3.9 ± 0.2 MJ·m⁻² to 1.9 ± 0.1 MJ·m⁻², and the peak heat release rate (pHRR) value was 89 % lower than that of cotton fabric. Its initial EMI SE_T reached 77.5 ± 2.4 dB, and even after 10 min of continuous flame exposure, the woven structure and conductive network remained intact, still providing 99.9 % shielding of EMWs. This flame-retardant coated EMI shielding fabric prevents the shielding performance failure of existing textiles due to combustion and maintains protection even in fire conditions, which carries significant practical value.

The effects of abrasive water-jet treatment (AWT) on the deformation of carbon steel surfaces and the adhesion of epoxy adhesives were analyzed. Different abrasive sizes and standoff distances were considered to evaluate the changes in surface properties of carbon steel produced during the AWT process in terms of surface roughness, surface topography, and residual abrasive distribution. Compared to conventional abrasive blasting, the AWT processing provided higher surface roughness and surface deformation ratio (DR), and significantly lower residual abrasives amount. Notably, the study found a tendency for adhesion to decrease with increasing surface roughness. This is in contrast to the conventional literature, which suggests that adhesion to paints and adhesives improves with increasing surface roughness up to a certain threshold level. On the other hand, DR showed a strong positive correlation with adhesion, but above a certain value, adhesion tended to be lower than that of the blast treatment. The findings indicate that it is preferable to consider both conventional surface roughness and DR concurrently when assessing adhesion. This study will contribute to a deeper understanding of the influence of surface properties during AWT on the adhesion performance of epoxy adhesives and suggest optimal surface treatment conditions for practical engineering applications.

A significant constraint concerning the utilisation of reduced graphene oxide (rGO) as pigment in water-based resins resides in its pronounced tendency to agglomerate. The present study proposes the employment of sodium cholate (NaCh) not solely as a dispersant but also as a green reducing agent of graphene oxide. The stability of the suspension was validated through zeta potential measurements, and functionalised rGO nanosheets with an approximative size of 500 nm were confirmed.

The barrier properties of the doped films were evaluated by electrochemical impedance spectroscopy, both on the free films and on those applied on carbon steel. The results obtained from both experiments demonstrated a consistent pattern. Very high impedance values were obtained for undoped resin and when doped with 0.05 wt%, 0.1 wt% and 0.2 wt% rGO, confirming the uniform dispersion of the particles within the resin. A model was developed to analyse the electrolyte uptake in the free films, which accounted for the heterogeneity of the films, with two clearly differentiated kinetics. When these films were applied on carbon steel, they also exhibited good barrier properties in 0.6 M NaCl during long immersion periods. In a more aggressive medium, a 5 M HNO₃ solution, the best performance was observed for the resin doped with 0.1 wt% and 0.2 wt% rGO, presumably due to the chemical resistance of the rGO.

The highest concentration, 0.5 wt% rGO, exhibited a rapid decrease in impedance values from the initial immersion time. This behaviour was attributed to the disruption of the polymeric network formation by the high amount of particles, resulting in a defective film. To facilitate the interpretation of the impedance spectra recorded for 0.5 wt% rGO, the Distribution of Relaxation Times (DRT) approach was employed, resulting in the proposal of a novel electrical equivalent circuit.

Considering the increasing efforts toward marine environment protection, the replacement of the conventional self-polishing antifouling coatings with their ecofriendly alternatives is urgently required. The key aspect of this transformation is the augmentation of the antifouling capabilities of matrix resins, which enables a substantial reduction in the use of antifouling agents. Consequently, research on high-performance self-polishing antifouling matrix resins is of utmost importance. Herein, to prepare a multifunctional zinc acrylate polymer for marine antifouling, an acrylate siloxane monomer (ASM) that undergoes free-radical polymerization with acrylate monomers was synthesized by grafting a hydroxyl-containing organosilicon intermediate (RSN-6018) with hydroxyethyl methacrylate. The prepared coating demonstrates excellent transparency in the short term after the addition of the ASM, addressing the issue of the poor compatibility of the organosilicon-modified zinc acrylate polymer. After immersion in seawater for 35 d, the organosilicon-modified zinc acrylate polymer exhibits a stable hydrolysis performance, facilitating the self-polishing of the coating. Because of the presence of the siloxane structure, the coating maintains stable hydrophobicity even after soaking in seawater for 35 d, demonstrating a contact angle of 115.0° ± 1°. The organosilicon-modified zinc acrylate polymer coating has an inhibition rate of up to 99 % against Staphylococcus aureus and exhibits antifouling effects lasting for more than two months in the actual marine environment. Overall, the proposed method offers a high level of innovation and provides an effective and novel approach for preparing modified self-polishing antifouling resins.

Polyurea, a versatile polymer, demonstrates significant potential in coating materials and other applications. Consequently, understanding polyurea systems, elucidating key mechanisms, and exploring research directions are critical. This paper presents the first comprehensive review of polyurea, focusing on mechanism analysis. It systematically examines the development history of polyurea, introduces its synthesis and preparation processes, expounds on its main performance characteristics and underlying causes, provides detailed analyses of modification methods and mechanisms, and explores its future applications and research directions. The study indicates that polyurea is a promising material developed relatively early, with diverse synthesis methods. Its performance advantages stem from block connections, microphase separation, and hydrogen bonding, with enhancement and functionalization achieved through modification. Polyurea exhibits excellent performance, including corrosion resistance, wear resistance, high elasticity, impact resistance, and self-healing, showing broad application prospects such as anti-corrosion and moisture-proofing, shock absorption and cushioning, anti-impact and explosion-proofing, sealing and bonding, lightweighting, and multifunctionality.

Complex self–healing methods and limited UV resistance restrict the application of reactive organic protective coatings for intelligent corrosion–protection in harsh marine environments. To address this, ultra–high aspect ratio boron nitride nanosheets (BNNS) were developed for uniform growth of polydopamine (PDA), loaded with benzotriazole (BTA). These BNNS/PDA/BTA (BPB) nanocontainers achieved high BTA loading (168.4 μg/mg) with efficient pH–sensitive release and excellent corrosion resistance (1.41 × 10¹⁰ Ω·cm²). After 30 days of immersion, the corrosion–rate of modified epoxy coatings was only 1.25 × 10⁻⁵ mm/year, and UV absorption of BPB maintained coating stability under prolonged exposure. This work informs heavy–duty anti–corrosion applications.

Insertion of a peritoneal dialysis (PD) catheter is one of the most common invasive procedures applied in treating chronic kidney disease. However, the PD catheter used in clinical practice is prone to bacterial adhesion and biofilm formation during peritoneal dialysis treatment. Therefore, endowing PD catheters with antibacterial properties and biocompatibility is urgently needed. Polypeptide-based antimicrobial agents have attracted increasing attention because they can combat multidrug-resistant microbes. In this work, we design two kinds of hyperbranched poly-l-lysine (HBPL) based coatings for catheters with arbitrary shapes. We demonstrated that the HBPL/isooctyl phosphate (IP) coating had strong antibacterial properties against S. aureus, while the HBPL/decanoic acid (DA) coating without C-N⁺ showed no bactericidal properties. We showed that the HBPL/IP coated catheters can effectively inhibit the growth of bacteria under static or dynamic flow conditions. Moreover, hemolysis experiments revealed that all the coatings had low hemolytic activities (<0.5 %). For the in vivo experiment, the HBPL/IP coating showed excellent biocompatibility. Overall, the HBPL/IP coating shows great promise as a facial, stable, and effective antibacterial coating to treat catheter-associated infections.

The use of solid aluminium as non-combustible cladding panels and the outer layer of aluminium composite panels (ACP) has raised concerns about fire safety in high-rise buildings. Solid aluminium begins to melt at temperatures above approximately 660 °C, which can exacerbate fire hazards by transferring significant heat from the exposed side to the unexposed side. This research investigates the fire performance of solid aluminium by incorporating two different commercially available water-based intumescent coatings (Coating-A and Coating-B) under fire conditions with high temperatures around 1000 °C. The study evaluates 0.5 mm thick solid aluminium panels with and without coatings to determine their effectiveness in mitigating fire risks. Comprehensive analyses, including SEM, XRD, TGA and fire tests, were conducted to assess the microstructure, elemental composition, thermal degradation and fire behaviour. The findings reveal that while solid aluminium without intumescent coating presents significant fire risks when exposed to high temperatures, intumescent coatings can substantially improve the fire resistance of solid aluminium. When Coating-A is applied to both sides of the solid aluminium, it reduces melting with a resistance factor of 0.70. But it still allows some flame spread. In contrast, Coating-B provides exceptional fire protection with a resistance factor of 0.86, preventing melting and flame spread when applied to one side. Between Coating-A and Coating-B, Coating B provides better fire protection, allowing only 14 % heat transfer. However, the key issue is the potential hazard of airborne char particles generated from Coating-B. These results underscore the importance of selecting effective intumescent coatings to enhance fire safety in solid aluminium cladding systems.
