Ions in seawater hinder direct sewage electrolysis due to the extreme corrosion of Cl − to the anode and reaction of Mg 2+ and Ca 2+ on the cathode producing solid substances, which reduce the electrolytic efficiency. However, traditional desalination consuming fossil fuel with massive CO 2 emissions threatens human survival. Therefore, zero-carbon emission, ultra-durable, large-scale production of freshwater from seawater for water electrolysis is urgently needed. Herein, a multifunctional system for seawater is demonstrated electrolysis based on ultra-durable solar desalination outdoors. The solar evaporators reach an evaporation flux of 1.88 kg m −2 h −1 with a photothermal conversion efficiency of solar energy as high as 91.3% with excellent ultra-durable salt resistance even for saturated saltwater due to the Marangoni effects. Moreover, the condensation of pure water from solar desalination based on the evaporation system reaches 0.54 L m −2 h −1 outdoors, which is suitable for a 20 cm × 20 cm engineered electrode equipped with a Janus membrane powered by a solar panel to produce H 2 outdoors. The ultrafast unidirectional transport of H 2 bubbles enabled by Janus membranes can greatly improve the H 2 production efficiency at a rate approaching 85 mL h −1 for continuous 24 h outdoors.

Developing highly durable coatings, endowing comprehensive protection capabilities of antifouling, drag reduction, and corrosion resistance in underwater settings, holds paramount significance for modern maritime undertakings. However, the inferior multifunctional compatibility and weak structural strength have proven to pose an extremely formidable challenge. Herein, this study reports an internally self-sliding coating that imparts liquid-repellence and ion permeation resistance without the necessity of a complex fabrication process. The key lies in combining integrated structure-function strategy with particle close-packing method of fluorine-grafted layered silicate particles. These particles demonstrate and exhibit a unique self-sliding property due to the weak van der Waals forces between the lamellae from the typical layered crystal structure. The durability and underwater protection of these coatings are clearly demonstrated by their outstanding mechanical wear resistance, a drag reduction efficiency of up to 25%, and the capacity to remain corrosion-free in saltwater for over 1000 h. Owing to the slippery frictional action and the closely packed surface microstructure, the coating demonstrates outstanding long-term stability and anti-permeability properties. This strategy offers a universal design framework for engineering ultra-durable coatings applicable to a diverse range of underwater comprehensive protection applications.

Incorporating zero-energy-input cooling-power generation technology into personal thermal management (PTM) systems is a promising solution for thermal energy utilization but remains a huge challenge due to lacking of effective assembly technology. In this work, a sustainable, cost-effective, superdurable, and nanostructured cellulosic metafabric (CWF) is reported that exhibits well radiative cooling function to achieve high-performance power generation. Through tailoring the viscoelasticity and optical performance in the electrospinning process, this metafabric demonstrates a unique micro/nano structure and anchored MOF assembly, 95.7 % solar reflectivity, 0.94 infrared emissivity, high mechanical strength, washability, surface hydrophobicity, and UV resistance can be achieved. This metafabric exhibited high cooling efficiency of 5.7 °C during direct sunlight in summer and anti-washing and UV stability. Furtherly, we coupled the CWF (as the cold sink) with a commercial thermoelectric device to assemble a power generation device. The device can output average voltage of 200 mV with an average temperature gradient of ≈20.1 °C under stimulated sunlight and shows superdurable power generation performance even after washing or folding (7000 cycles) use. An outdoor test demonstrated it can deliver a high output voltage of 519 mV in Nanjing, China. The cooling metafabirc shows great promise for practical applications in wearable power generation devices.

Carbon fiber (CF) has been widely used in aerospace, military, infrastructure, sports, and leisure fields owing to its excellent mechanical properties, superior corrosion and friction resistances, excellent thermal stability, and lightweight. However, the ultrablack appearance derived from the extremely strong absorption of light throughout the entire visible region makes it difficult to satisfy the aesthetic and pleasurable demands of the colorful world and limits their applications in a broader field. Herein, inspired by the Japanese jewel beetle, a double-layer ultrathin Al2O3/TiO2 composite structure was fabricated on CFs by the atomic layer deposition method. CFs exhibited desired color diversity by controlling the thickness of Al2O3 and TiO2 films without changing the total thickness of the composite film’s structure. Meanwhile, colored CFs have no color change/destruction after a series of environmental durability measurements and exhibited remarkable superdurability and excellent flame retardancy. Our work provides insights for innovative, high-performance, and multifunctional CF that can help achieve high quality and sustainable development of the CF industry.

Developing versatile, scalable, and durable coatings that resist the accretion of matters (liquid, vapor, and solid phases) in various operating environments is important to industrial applications, yet has proven challenging. Here, we report a cellular coating that imparts liquid-repellence, vapor-imperviousness, and solid-shedding capabilities without the need for complicated structures and fabrication processes. The key lies in designing basic cells consisting of rigid microshells and releasable nanoseeds, which together serve as a rigid shield and a bridge that chemically bonds with matrix and substrate. The durability and strong resistance to accretion of different matters of our cellular coating are evidenced by strong anti-abrasion, enhanced anti-corrosion against saltwater over 1000 h, and maintaining dry in complicated phase change conditions. The cells can be impregnated into diverse matrixes for facile mass production through scalable spraying. Our strategy provides a generic design blueprint for engineering ultra-durable coatings for a wide range of applications.

Superhydrophobic materials are attractive for industrial development but plagued by poor mechanical stability. Herein, a superdurable full-life superhydrophobic composite block is designed and fabricated by embedding near-zero contractive superhydrophobic silica aerogel into a rigid iron-nickel foam structured similarly to a regular dodecahedron. The synergistic protection afforded by these materials ensures superrobust mechanical stability for the composite block, which features a high compressive strength of up to ≈7.4 MPa, and ultralow Taber abrasion of down to ≈0.567 mm after withstanding 50 000 cycles, and highly efficient water harvesting capability of up to ≈3114.3 mg min −1 cm −2 at a supercooling degree of 40 K. This robust material system provides a novel strategy to design superhydrophobic materials capable of withstanding extreme conditions, including high temperature, humidity, pressure, and abrasion.

Omniphobic liquid-like surface (LLS) offers excellent dynamic liquid repellency owing to the highly mobile polymer chains mediating at the solid–liquid interface. These polymer chains, often achieved by surface grafting, are not durable against abrasion or oxidation, which seriously hinders their practical application. Here we report a new vapor-based approach to create transparent nanogradient coating for LLSs with unprecedented mechanical strength and durability. The nanogradient coating is composed of a sandwich structure with an ultrathin primer, a rigid bulk, and a nanocomposite surface with abundant polydimethylsiloxane-like chains, all of which achieved via sequential plasma polymerization of a linear and a cyclic siloxane. The plasma-polymerized cyclic siloxane enables coating good mechanical strength while the plasma-polymerized linear siloxane confers coating sub-nanometer roughness and excellent dynamic liquid repellency. The resultant coating exhibits contact angle hysteresis < 5° towards many low-surface-energy liquids, as well as good mechanical strength with the hardness exceeding 1 GPa and superior durability enduring 100,000 cycles of abrasion. The coating also survived industrial standard thermal and accelerated UV-aging tests without losing its liquid repellency and transparency. The reported method is facile, scalable, and substrate-independent, offering exciting new opportunities towards industrial fabrication and real-world application of LLS.
