Membrane distillation (MD) is a promising method to produce fresh water by desalination of seawater and saline industrial wastewater. Hydrophobic membranes for MD tend to scaling and fouling during operation. Herein, liquid-infused membrane (LIM) with slippery surface and gating properties is proposed for anti-scaling/fouling MD. The LIM, denoted by PTFE-2-FL, was fabricated by coating a ∼ 2 μm-pore-sized polytetrafluoroethylene (PTFE-2) with dopamine and polyethyleneimine, silica nanoparticles, and fluoride (abbreviated as F), followed by lubricant filling (abbreviated as L). The lubricant capillary-locked in micropores forms a gate that can be reversibly opened for vapor under proper pressure, but prevents water from passing through, thus achieving vapor/water separation with a maximum salt rejection of 99.99 %. Compared with the non-lubricated membrane, PTFE-2-FL exhibits more stable separation performance, indicating the excellent anti-scaling/fouling properties owing to the non-adhesive lubricant surface avoiding contact between contaminants and membrane substrate, especially when treating high-salinity feed (NaCl of 250 g·L −1 ), simulated gypsum solution (NaCl of 35 g·L −1 , Na 2 SO 4 of 20 mM and CaCl 2 of 20 mM), organic compound-contaminated solutions (humic acid or sodium alginate of 500 mg·L −1 ), and inorganic–organic mixed solutions. PTFE-2-FL also has good reusability compared to the irreversible fouling of the hydrophobic membrane in cyclic MD process.

In this work, we designed and fabricated an anti-scaling and anti-corrosion superhydrophobic 1H,1H,2H,2H-perfluorodecyl triethoxysilane (PFDS)/ethylenediamine tetraacetic acid (EDTA)/anodized copper oxide (ACO) coating at the surface of a copper alloy. The water contact angle of PFDS/EDTA/ACO coating reaches 164.53°, showing superhydrophobicity, which will reduce the contact between scale crystals, corrosive medium and substrates, and help to inhibit scaling deposition and corrosion. Results show during the CaCO 3 deposition test, EDTA molecules, EDTA-Zn 2+ and EDTA-Cu 2+ chelates stored in the micro-structure of superhydrophobic PFDS/EDTA/ACO coating are released to the interface and help to improve scaling prevention. After soaking for 48 h, the CaCO 3 scaling mass of PFDS/EDTA/ACO coating was only 27.0 % that of ACO coating, and the corrosive protection efficiency of the superhydrophobic PFDS/EDTA/ACO coating was improved by 3.4 times that of ACO coating. Studies indicated that the anti-scaling and anti-corrosion of the superhydrophobic PFDS/EDTA/ACO coating contributes to the cooperation of superhydrophobic air film and the potential storage and dynamic release of EDTA, as well as the passivation layer formed on the substrate.

Superhydrophobic surface has attracted great attention because of its potential applications. In this work, a facile method for fabrication of a superhydrophobic coating on pipeline steel surface is reported. A hierarchical structured coating with nanoflakes was fabricated via electrodeposition and solution-immersion, and then the coating achieved superhydrophobic with water contact angle about 157° and sliding angle around 3° after fluorination modification. The surface morphology and wettability changed with different experimental parameters were also investigated. The prepared superhydrophobic coating exhibited efficient self-cleaning and anticorrosion properties. Furthermore, the anti-scaling property of this superhydrophobic coating was confirmed since the CaCO 3 crystals on the superhydrophobic coating were mainly needlelike compared to the rhombohedral CaCO 3 crystals on the surface of steel substrate. This superhydrophobic coating maintained good long-term stability in air, and mechanical and thermal stability under certain environment. This superhydrophobic coating provided potential multifunctional applications, such as self-cleaning, corrosion resistance and anti-scaling properties, of deposition metal or alloy coating.

While flow-electrode capacitive deionization (FCDI) is recognized as an attractive desalination technology, its practical implementation has been hindered by the ease of scaling and energy-intensive nature of the single-cell FCDI system, particularly when treating brackish water with elevated levels of naturally coexisting SO42– and Ca2+. To overcome these obstacles, we propose and design an innovative ion-selective metathesis FCDI (ISM-FCDI) system, consisting of a two-stage tailored cell design. Results indicate that the specific energy consumption per unit volume of water for the ISM-FCDI is lower (by up to ∼50%) than that of a conventional single-stage FCDI due to the parallel circuit structure of the ISM-FCDI. Additionally, the ISM-FCDI benefits from a conspicuous disparity in the selective removal of ions at each stage. The separate storage of Ca2+ and SO42– by the metathesis process in the ISM-FCDI (46.25% Ca2+, 14.25% SO42– in electrode 1 and 4.75% Ca2+, 35.25% SO42– in electrode 2) can effectively prevent scaling. Furthermore, configuration-performance analysis on the ion-selective migration suggests that the properties of the ion exchange membrane, rather than the carbon species, govern the selectivity of ion removal. This work introduces system-level enhancements aimed at enhancing energy conservation and scaling prevention, providing critical optimization of the FCDI for brackish water softening.

Scale deposition and metal corrosion, especially in the petroleum industry , have always been serious issues that seriously affect economic efficiency and safety. However, conventional anti-scaling strategies including mechanical descaling and chemical detergents are energy-consuming and environmentally damaging, which can't achieve efficient and long-term protection. Based on mechanical descaling and chemical detergents, and anti-corrosion strategies based on filler are inadequate to realize efficient protection. Herein, this work reports a novel UV-curable polymer coating with long-term anti-scaling and anti-corrosion properties. The excellent anti-scaling capability was achieved by inhibiting interfacial nucleation and reducing interfacial adhesion work of scaling products. Significantly, the anti-scaling capability of the designed coating mainly originates from two aspects: inhibiting interfacial nucleation and reducing interfacial adhesion work of scaling. Compared with pure polyurethane acrylic coating (0 % FGSS), the 20 % FGSS coating shows significantly improved scaling repellence even after a 240 h dynamic scaling test while maintaining a fairly low theoretical adhesion work (≈0.1 mN/m). This outstanding anti-corrosion capability of the FGSS coating mainly originates from two aspects: the physical barrier effect of the air layer and low surface energy resistance barriers with dynamic FGSS brushes. The physical barrier effect of the air layer and the low surface energy resistance barriers also lead to outstanding anti-corrosion property (with the |Z| 0.01 Hz value maintained at 10 8 Ω·cm 2 ). This study presents a simple and effective design and fabricated strategy, paving a new pathway for developing UV-cured coatings with unique anti-corrosion and anti-scaling properties. This facile and effective UV-curable polymer coating shows great potential in metal protection and paves a new pathway for the development of long-term functional protection coatings.

Pressure-driven distillation (PD), as an emerging technology, holds tremendous potential for producing freshwater from nontraditional water sources. In this process, a sufficient hydraulic pressure is applied to drive water evaporation and vapor transport across a vapor-gap membrane. The development of the PD process critically depends on the availability of robust and large-area superhydrophobic membranes. Here, we propose an ultraselective superhydrophobic thin-film composite (TFC) vapor-gap membrane with confined transport channels toward the PD process, which can be manufactured scale-up through a facile swelling–assisted deposition strategy. The TFC-PD membrane demonstrates separation capabilities, achieving near-complete rejections of nonvolatile solutes, including salts, boron, and urea. Featured by a vapor-gap superhydrophobic layer, the TFC-PD membrane exhibits superior chlorine and scaling resistance and maintains stable performance over time without being oxidized or scaling. This work offers notable advancements in the microstructural design of PD membranes and the development of scalable robust TFC membranes for the PD process.

Scale deposition severely degrades the heat-transfer efficiency of industrial equipment, leading to substantial energy wastage. While several advanced scalephobic surfaces have been developed to mitigate scaling, their poor stability under harsh operating conditions hinders practical implementation. Herein, we report a dynamic hydration layer-synergistic ion-releasing (DHLIR) coating that exhibits exceptional energy-saving potential, enabled by ultrahigh scale resistance under boiling conditions. The DHLIR coating was facilely fabricated via a combined spraying and heat-treatment process, utilizing aluminum phosphate (AP) as the inorganic binder, titanium dioxide (TiO₂) nanoparticles as the structural reinforcement phase, and hexagonal boron nitride ( h BN) nanosheets as the thermally conductive filler. Notably, the superior scalephobic performance of the DHLIR coating stems from two key mechanisms: the surface hydration layer minimizes mineral ion adsorption, while the released scale inhibitors reduce scale adhesion. Furthermore, the DHLIR coating demonstrates robust durability under extreme environments, including high temperatures, abrasion, and corrosive liquids. In a simulated industrial boiler setup, the DHLIR coating conserved approximately 15.3 % of energy compared to stainless steel. This work thus presents a promising strategy for anti-scaling and energy conservation in boiling environments.

SiO 2 -EDTA composite particles are prepared by using nano-silicon dioxide (SiO 2 ) as the loading particle and ethylenediaminetetraacetic acid (EDTA) as the scaling inhibitor. Then, SiO 2 -EDTA particle and polytetrafluoroethylene (PTFE) micro powder are added in water-based silanized maleic anhydride-g-poly(1,2-butadiene) (SiMLPB) to fabricate composite coatings with good anti-scaling and anti-corrosion properties. The water contact angles (WCA) of SiMLPB increase to a maximum of 103° with the addition of PTFE at 3 wt% and then decrease slowly; based on this formulae, the WCA improves to 109 o when SiO 2 -EDTA is added up to 2 wt%. SiMLPB/PTFE coatings exhibit good corrosion resistance with the addition of PTFE; the SiMLPB/3%PTFE/2%SiO 2 -EDTA composite coating possesses impedance (| Z | 0.01Hz ) value at 2 orders higher than that of the SiMLPB/PTFE0 coating at low frequency, suggesting the much greater improvement in corrosion resistance due to the synergistic effects of adding nanoparticle as a surface modifier and EDTA as a corrosion inhibitor. The deposition of CaCO 3 on this SiMLPB/PTFE/SiO 2 -EDTA composite coating reaches 0.0132 g/cm 2 after 120 h scaling test, which is about 79% lower than that on the pure SiMLPB coating, resulting from the chelation of EDTA that promotes the formation of more unstable scales. The improvements in both anti-corrosion and anti-scaling performances are attributed to the hydrophobic function of PTFE and nanoparticle as well as the dual functions of EDTA at an appropriate addition of SiO 2- EDTA.

In this study, a novel diethylene triamine penta(methylene phosphonic acid) (DTPMPA)- and graphene oxide (GO)-modified superhydrophobic anodized aluminum (DGSAA) coating was fabricated. The obtained coatings were characterized by scan electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and Raman analysis. After immersion in the supersaturated CaCO 3 solution for 240 h, the scaling mass of the DGSAA coating is only 50% of that of the SAA coating. The excellent anti-scaling performance of the DGSAA coating comes from three barriers of the air layer, the DTPMPA:Ca 2+ chelate, and the lamellar GO, as well as the further active anti-scaling of DTPMPA:Ca 2+ at the coating-solution interface. DTPMPA and GO at the surface of the DGSAA coating exhibit an insertion structure. In the electrochemical impedance spectroscopy measurement, the impedance modulus of the DGSAA coating is three orders-of-magnitude higher than that of the anodized aluminum. The synergistic effect of DTPMPA stored in the porous structure of anodized aluminum and the barrier protection of superhydrophobicity and GO contributes to the excellent comprehensive performance of the DGSAA coating. This research provides a new perspective for designing anti-scaling and anti-corrosion superhydrophobic bi-functional coatings.

This study presents the fabrication of pinecone-structured ZnO microparticles using a solvothermal method, which were subsequently applied to steel surfaces in combination with epoxy resin and perfluorosilane to create a superhydrophobic coating, termed FluoroZnO-Fe. The low surface energy and micro-nano hierarchical structure of the prepared coating significantly enhance its water repellency and reduces its adhesion, resulting in water contact angle as high as 161° and sliding angle as low as 2°. The FluoroZnO-Fe surface demonstrated exceptional stability. Its water contact angle remains above 150° and water sliding angle remains below 5° even after treated with mechanical abrasion, high temperatures, and exposure to acidic and alkaline environments. Importantly, when subjected to heated circulating brine, the FluoroZnO-Fe coating exhibited remarkable anti-scaling properties, achieving a 93.4% reduction in scale deposition compared to untreated bare steel. This research highlights the potential of FluoroZnO-Fe coatings for industrial applications where corrosion resistance and self-cleaning properties are critical.

Scaling severely impairs the efficiency, safety, and service life of industrial pipelines. While anti-scaling coatings offer an efficient and environmental-friendly solution, their long-term durability remains challenging. Herein, a robust gradient liquid-like coating (gLLC) is fabricated via plasma-enhanced chemical vapor deposition for long-term anti-scaling applications. By integrating a rigid inorganic bulk that gradually transitions to surface enriched in mobile polysiloxane chains, the gLLC combines exceptional mechanical strength (modulus = 14.39 ± 0.17 GPa; hardness = 1.57 ± 0.03 GPa) with dynamic liquid repellency (hexadecane sliding angle = 3°; water sliding angle = 11°). The fluorine-free coating demonstrates potent anti-scaling efficacy against CaCO 3 and CaSO 4 under both static and dynamic conditions, achieving over 75% reduction in scaling mass on stainless steel substrates. Remarkably, the gLLC maintains superior performance over a 90-day dynamic recirculation test, with scale accumulation limited to 1.5 mg cm −2 , representing one of the best long-term performance of anti-scaling coatings reported to date. Furthermore, the gLLC reduces scale deposition by 89% under oil-water emulsion. The outstanding scale resistance is attributed to the low-energy, smooth, and dynamically mobile surface combined with the mechanically durable gradient structure. This work establishes a scalable and environmentally benign strategy for durable anti-scaling surfaces, offering broad potential for deployment in petroleum, chemical, and water treatment industries.

Tailoring nanofiltration (NF) membrane with low scaling potential and high energy efficiency is of critical importance to its practical implementation for groundwater remediation . In this study, interfacial polymerization was performed on the surface of an intermediate layer of TA-Fe/CNTs coated polyether sulfone (PES) substrate to obtain a loose NF membrane (TFNi-x) with negative surface charges and optimized water transport path for selective permeation of scaling ions and higher water permeance . The obtained TFNi-10 intermediated with a moderate amount of CNTs (10 μg/cm 2 ) exhibited 80.5 % higher selectivity of Ca 2+ over SO 4 2− and 156 % higher water permeance compared to the control TFC while maintaining a high PFOA rejection (∼97.3 %). For the gypsum scaling measurements, TFNi-10 showed better anti-scaling behavior and 40 % less pressure energy consumption for the same recovered water volume (2.2 L), resulting in the higher water recovery and lower energy cost of specific volume of the permeate. It was contributed by the synergistic effects of the strong affinity of TA-Fe to piperazine monomer and the gutter effect of TA-Fe/CNTs interlayer . Our results paved a new way of fabricating novel NF membrane with tailored intermediate layer for optimized interfacial polymerization to realizing groundwater remediation in a cost-effective manner.
