Superhydrophilic SiO 2 coatings offer unparalleled advantages in terms of antifogging properties. However, they show suboptimal mechanical abrasion resistance and environmental durability, limiting their application. Accordingly, research has focused on the trade-off between hydrophilicity and mechanical abrasion resistance as well as between environmental durability and visible transmittance in superhydrophilic SiO 2 coatings. Herein, a composite-structure coating with a densely distributed particulate phase and enhanced crosslinking strength is developed without the use of organic compounds. The coating exhibits remarkable transparency and antifogging properties, with an average transmittance similar to that of bare glass and a water contact angle of approximately 0°. Moreover, the coating exhibits impressive hardness and adhesion of up to 4H and 5B, respectively. The coating retained its antifogging properties even after undergoing 500 cycles of wear induced using a 3000-mesh sandpaper, impact of sand (40 g) dropped from a height of 40 cm, 10 weeks of exposure to the outdoor environment, and 25 h of immersion in water. The test results demonstrate that the coating exhibits satisfactory mechanical abrasion resistance and environmental durability, which are essential for its practical applications. The composite structure formed using linear SiO 2 molecules as crosslinking agents with spherical SiO 2 nanoparticles considerably enhances the adhesion and abrasion resistance of the coatings. Overall, the developed composite-structure coatings will facilitate their commercial viability and expand the application of superhydrophilic materials in various research fields.

Carbon fibers (CFs) are widely used in various cutting-edge fields, such as aerospace, military, automobiles, and sports, owing to their unique combination of excellent mechanical properties, good thermal stability, and lightweight. However, their inherent super-black appearance makes it difficult to satisfy the aesthetic/fashion requirements of the colorful world, and the flammability of CFs severely limits their practical utilization in high-temperature and other extreme environments. Herein, we fabricated full-color tunable colored CFs on a large-scale via atomic layer deposition, based on the monolayer film interference strategy. CFs exhibited brilliant colors and excellent environmental durability in extreme environments, such as intense ultraviolet (UV) irradiation, accelerated laundering, friction, high-temperature, and low-temperature treatments. Colored CFs also exhibited excellent fire-retardant performance that could withstand alcohol-lamp flame burning for 60 min. Our work provides insights into an innovative material/structural design that can help achieve rapid development of the CF industry and global carbon neutrality/sustainability. Graphical Abstract

Obtaining mechanical stability and environmental durability is a key but challenging issue in the development of superhydrophobic coatings. Here, a superhydrophobic coating with high mechanical stability and environmental durability was fabricated through layer-by-layer spraying the silicone/epoxy resin composite and micro-nanoparticles. By layer-by-layer spraying, the resins and the micro-nanoparticle could be modulated separately. The use of the silicone/epoxy resin composite not only adjusts the hardness of the coating, but also allows the fabrication of special composite structures consisting of resin framework and particle clusters by adjusting the solubility between the resin material and the solvent of the micro-nano particles’ solution. Based on the high hardness and special composite microstructure, the superhydrophobic coatings exhibit high mechanical stability (abrasion 45 m under a load of 200 g) and environmental robustness (boiling water immersion for 24 h). The particle clusters can continuously replenish the micro-nano-particles lost during the surface abrasion, thus prolonging the coating’s service life. In addition, the coatings possessed an ultra-high corrosion inhibition efficiency of 99.99% and drag reduction effect (2~21% at the velocity of 2~5.75 m/s). The presented work provides valuable insights into the design and fabrication of highly stable superhydrophobic coatings.

Integrating environmental robustness, energy-efficient recoatability and multi-scenario applicability into a single durable coating that can resist the accumulation of liquid, solid, and mold contaminants is critical for the sustainable development of the coatings industry, yet remains a significant challenge. Here, this issue is addressed by developing a novel hydrophilic-hydrophobic conversion strategy to engineer an environmentally robust organic/inorganic hybrid superhydrophobic coating with remarkable anti-soiling properties and pH-induced recoatability. This conversion, achieved through surface chemistry regulation incorporating hydrophobic hydrocarbon chains and aminopropyl functional groups, yields a coating with a high water contact angle (WCA) of 155.4° and a low sliding angle (SA) of 1.3°. Notably, the WCA can reversibly transition to 0° within 15 s under pH adjustment. The wide range of the surface energy variations enables effective recoatability and restores surface wettability in damaged coatings, with an adhesion strength up to 5.34 MPa, allowing for the in-situ reuse of old coatings. The uniform distribution of modified silica nanoparticles within semi-cured epoxy matrix imparts satisfactory environmental durability, allowing the composite coating to retain its superhydrophobicity after enduring various harsh conditions, including 100 cycles of sandpaper abrasion, 70 cycles of tape-peeling, 120 h of water immersion, and 168 h of heat and humidity exposure. Additionally, the coating demonstrates enhanced anti-mold performance, achieving a grade 1 rating. This work introduces a novel design and fabrication method for multifunctional pH-triggered recoatable superhydrophobic coatings with enhanced environmental robustness that significantly extends their lifespan and adaptability.

Removing microplastics (MPs) from water has been a huge challenge due to their inherent features including small size and high stability. In this research, inspired by the active adsorption and passive adhesion mechanisms of corals to MPs, a new strategy to fabricate polydopamine enhanced magnetic chitosan (PDA-MCS) aerogels was developed with a target to match the surface properties of MPs, achieving high MPs removal efficiency. PDA-MCS aerogels were highly efficient in adsorbing polyethylene terephthalate (PET) microplastics in water at pH values of 6–9, with a removal efficiency of up to 91.6%. Even after three recycles, PDA-MCS aerogels still displayed comparatively high removal efficiency (83.4%). Kinetic and isothermal experiments showed that the adsorption process was the result of electrostatic interactions and physical adhesion between aerogels and microplastics. Moreover, PDA-MCS aerogels maintained high removal efficiency under simulated environmental conditions, and the removal efficiency of PET, polyethylene (PE) and polystyrene (PS) microplastics in waters reached 97.3%, 94.6%, and 92.3%, respectively. Therefore, high-efficiency environmentally durable aerogels adsorbent materials have the potential for the removal of MPs from the aquatic environment.

A scalable strategy is proposed for preparing ultra-flexible transparent heaters (THs) with ZnO-Ag core–shell nanowires (ZnO@Ag NWs) embedded in polyvinylidene fluoride composite films. The obtained THs exhibit a high average transmittance of 85.8% in the visible spectral range and excellent heating performance. The maximum saturation temperature can reach 153 °C within 10 s at an input voltage of 4.0 V. Furthermore, the saturation temperature of THs has not changed significantly after 1000 bending cycles with a curvature radius of 0.5 mm, demonstrating excellent mechanical flexibility. In particular, the THs possess environmental endurance, and no significant deterioration in performance can be found after exposure to high humidity (relative humidity: 85%) and ultraviolet ozone (254 and 185 nm) irradiation for 10 h, which is attributed to the protective role provided by the covering of ZnO shells on the Ag NWs. These outstanding parameters make the fabricated THs to be promising for application in wearable systems, medical thermotherapy pads and industrial defrosters.

This study hypothesized that engineering ceramic-polymer composites with hierarchical porosity and stress-adaptive silica reservoirs can reconcile the trade-off between icephobicity and mechanical resilience in superhydrophobic coatings, enabling robust anti-icing solutions for aerospace, energy infrastructure, and cryogenic systems. The hierarchical porosity for water confinement and ceramic microspheres for load dissipation is predicted to enable spontaneous ice shedding while resisting abrasive degradation. Methyltrimethoxysilane (MTMS)-tetraethoxysilane (TEOS) co-condensation was leveraged to synthesize mesoporous ceramic microspheres with encapsulated hydrophobic silica reservoirs. Through alternating layer-by-layer spraying, these microspheres were integrated with acrylic resin (AR) to create a gradient modulus coating. The optimized coating achieved ultralow ice adhesion (20.9 ± 0.43 kPa) through nanopore-induced Cassie-state stabilization (contact angle: 161.3 ± 0.31°, hysteresis: 2.3 ± 0.19°). Surface nanopores promoted spontaneous droplet jumping via Laplace pressure differentials and robustly precluded the pinning of supercooled water, thereby triggered ice-droplets self-dislodging via freezing-induced hydrostatic pressure. Mechanical tests demonstrated exceptional durability with <7 % contact angle reduction after sandpaper abrasion, repeated de-icing cycles, tape peeling, acid-base immersion, infrared irradiation, and protracted weathering, attributed to stress-adaptive silica release from fractured ceramic shells. This architecture establishes a materials design paradigm for extreme-environment anti-icing applications.

Hydrogels have found broad applications such as sensing and electrolytes; however, the insufficient sensing sensitivity, inherent environmental stability limitations, and poor mechanical properties hinder their further development in these areas. In this work, a multifunctional eutectogel with a rich hydrogen bond network and microphase-separated structure is prepared through one-step photopolymerization by mixing a binary deep eutectic solvent (DES) [zinc chloride (ZnCl2) and ethylene glycol (EG)] with a polymerizable deep eutectic solvent (HCAG) [acrylic acid (AA), hydroxyethyl acrylate (HEA) and choline chloride (ChCl)]. This HCAG/DES gel exhibits a fracture stress of 2.25 MPa, toughness of 8.4 MJ/m3, self-healing efficiency of 86.4%, transmittance over 82%, and adhesive strength reaching 342 kPa. The eutectogel also exhibits notable thermoelectric conversion capability, generating a thermoelectric voltage of 78.3 mV under a temperature difference of 40 K. In addition, the eutectogel exhibits effective antibacterial activity against S. aureus and E. coli. The eutectogel-based strain sensors exhibit high sensitivity (GF up to 6.063) and a broad sensing detection range (0–600%) as well as fast response time (0.6 s). These combined features enable the eutectogel-based sensor to monitor movement and transmit encrypted signals at −20 °C, demonstrating potential for applications in flexible wearable electronics within low-temperature environments.

Conventional preparation of Janus membranes with asymmetric wettability focuses on the preparation of extreme hydrophilic side and hydrophobic side, but suffers from pore clogging, low liquid transfer and collection efficiency and short service life. In this study, Janus wood (JW) with a continuous wettability gradient was created throughunidirectional vacuum impregnation of a hydrophobic solvent after the delignification of wood. Digital image correlation (DIC) and layer-by-layer contact angle assessment were utilized to examine the thickness-dependent wettability gradient of the JW membrane. The JW membrane completed the modification of the cell walls without blocking the cell lumens. The presence of wettability gradient in the JW membrane effectively reduced the capillary force of liquid penetration, resulting in decreased adhesion and stagnation of liquid on the membrane surface, and increased flow rate and transport efficiency. Based on the continuous wettability change of the JW membrane, the JW membrane was endowed with the ability to act as a “unidirectional valve” to enable continuous and rapid directional transport of liquids. The mechanical properties of the JW membrane prepared by the unidirectional introduction method were significantly improved, rendering them highly stable and environmentally durable. The fog collection efficiency of the JW membrane was maintained at 97.7% over 10 repeated use cycles. For light oil/water and heavy oil/water mixtures, JW membrane maintained an efficiency of 99.6% or higher. Unlike conventional surface modification methods, the unidirectional introduction method proved practical and effective for modifying the JW membrane in the thickness direction. Furthermore, the prepared JW membrane was sustainable, inexpensive, durable, and environmentally friendly. This study provides a wide range of potential applications in fields such as droplet manipulation, multi-liquid separation, industrial wastewater purification, and microfluidics.

Effective control of airborne particulate matter and gaseous radioactive iodine is a critical challenge for nuclear facility safety and radioactive waste remediation. Although conventional systems for particle filtration and iodine adsorption are widely implemented, their inherent radioactive contamination leads to prohibitively high post-treatment disposal costs. Herein, we report a novel dual-functional composite material, NSiO-ESF@ACF, fabricated via a metal-wire-based needleless electrospinning technique that integrates electrospun nanofibers with activated carbon fibers (ACFs) in a synergistic architecture. The engineered composite membrane demonstrates unprecedented multifunctionality: outstanding particle filtration efficiency (99.98 % removal of PM₀.₃ at 205.9 Pa), a record-high iodine adsorption capacity (764.56 mg/g with outlet iodine concentration < 5 %), and scalable manufacturability. The nanofibers, with diameters comparable to the mean free path of air molecules, facilitate slip-flow-dominated transport, thereby achieving low pressure drop (≤ 205.9 Pa). The incorporation of hydrophobic silica nanoparticles modulates fiber diameter and enhances environmental durability, maintaining >99.95 % filtration efficiency after three wet-dry cycles. Notably, a synergistic interaction between the particulate interception layer and the iodine adsorption layer is observed, yielding a combined performance greater than the sum of the individual components (1 + 1 > 2). This technological advancement simultaneously addresses three core challenges in nuclear air purification systems: high-efficiency particulate retention, superior iodine capture, and cost-effective scalable fabrication. The NSiO-ESF@ACF composite sets a pioneering example for multifunctional integration and environmental resilience in radioactive contaminant management.

The rapid development of touchscreen interfaces and portable electronics has increased the demand for anti-fingerprint and antireflective coatings, which enhance screen visibility and improve the user's visual experience. However, existing oleophilic or oil-repellent coatings often fail to deliver both high transparency and durable anti-fingerprint performance under real-use conditions. In this study, an antireflective coating was fabricated based on chitin nanofibers (ChNFs) to provide both amphiphobic and anti-fingerprint protection for touchscreen displays. The ChNF-based coatings with abundant large-sized nanopores were fabricated via freeze casting and subsequent modification with PFDTES deposition. The PFDTES-modified chitin nanofiber (P-ChNF) coatings combined the anti-fingerprint performance of both water and oleic acid contact angles of 153° and 118°, and increased glass transmittance at 550 nm by ~5 %. The P-ChNF coatings possessed good environmental durability and mechanical robustness, maintaining their anti-fingerprint and antireflective properties under harsh conditions. Notably, the smartphone screen coated with P-ChNF exhibited a substantial reduction in fingerprint residue, confirming improved anti-fingerprint performance. This work not only demonstrates that ChNFs are a promising candidate for meeting the growing demand for protective coatings in touchscreen displays, but also offers a feasible and efficient strategy to do so, thereby promoting the green and sustainable development of the anti-fingerprint coating industry.

Superwetting cotton fabrics with surface wettability from underwater superoleophobic to superhydrophobic were designed and prepared by modification with polymerized plant polyphenol for on-demand oil/water separation. Hydrophilic poly(tannic acid) (PTA) particles were in-situ deposited onto the surface of polyethyleneimine (PEI)-coated cotton fabric. The resulting underwater superoleophobic cotton fabric (UWSOCF) was a water-removing material to separate water/light oil mixtures with a separation efficiency higher than 99.8%. After modifying UWSOCF with hydrophobic octadecylamine (ODA), superhydrophobic cotton fabric (SHCF) was obtained. SHCF was an oil-removing material suitable for separating water/heavy oil mixtures with a separation efficiency higher than 96%. Both UWSOCF and SHCF exhibited excellent mechanical robustness and environmental durability and could resist mechanical abrasion, tape peeling, high temperatures, organic solvents, and acidic/alkali erosion.
