Abstract :
Highly transparent,durable,and flexible liquid-repellent coatings are urgently needed in the realm of transparent materials,such as car windows,optical lenses,solar panels,and flexible screen materials.However,it has been difficult to strike a balance between the robustness and flexibility of coatings con-structed by a single cross-linked network design.To overcome the conundrum,this innovative approach effectively combines two distinct cross-linked networks with unique functions,thus overcoming the chal-lenge.Through a tightly interwoven structure comprised of added crosslinking sites,the coating achieves improved liquid repellency(WCA>100°,OSA<10°),increased durability(withstands 2,000 cycles of cot-ton wear),enhanced flexibility(endures 5,000 cycles of bending with a bending radius of 1 mm),and maintains high transparency(over 98%in the range of 410 nm to 760 nm).Additionally,the coating with remarkable adhesion can be applied to multiple substrates,enabling large-scale preparation and easy cycling coating,thus expanding its potential applications.The architecture of this fluoride-free dual cross-linked network not only advances liquid-repellent surfaces but also provides valuable insights for the development of eco-friendly materials in the future.

Abstract :
Nowadays, the development of all-biomass aerogel fibers that integrate robust mechanical properties with superior thermal insulation remains a significant challenge. In this study, all-biomass core-shell structural aerogel fiber with the cellulose acetate shell and the silk fibroin core was developed to address these issues. The resulting cellulose acetate-silk fibroin aerogel fiber demonstrated impressive mechanical properties, with the stress and strain at break of 28.18 MPa and 104%, respectively. These properties are attributed to lithium chloride-induced slow molding and heat treatment-derived crystallization enhancement. Furthermore, the cellulose acetate-silk fibroin aerogel fiber possessed excellent water resistance and easy dyeability. Notably, based on the multilevel porous structure, low thermal conductivity, and core-shell structure of aerogel fiber, the knitted fabric exhibited outstanding thermal insulation performance, such as a |Delta T| of 60.6 at hot stage temperature of 120 degrees C, outperforming previous studies. Consistent with the experimental findings, the numerical simulation results revealed that the exceptional performance could be attributed to the macro-/nano-sized pores in the cellulose acetate shell capturing stationary air for suppressing thermal conduction/convection, and walls in the silk fibroin core enhancing infrared reflectance for preventing thermal radiation. This innovative approach paves the way for designing sustainable aerogel fiber and multifunctional textiles, with promising applications in personal thermal management.

Abstract :
Alkaline water electrolysis is one of the most prospective technologies for large-scale production of green hydrogen. Nevertheless, current porous membranes face the problem of weak ion transport or poor gas barrier performance. Here, we demonstrate a facile yet massive two-step casting and phase separation strategy to design a thin, asymmetric pore-structure modulated composite membrane for efficient, safe, and industrial-grade alkaline water electrolysis. The prepared composite membrane shows better electrolytic performance (1.71 V at 1 A cm-2) and stability (working for 6352 h). In addition, an industrial-grade electrolyzer equipped with composite membranes exhibits higher hydrogen production efficiency (1.03 Nm3h-1), H2 purity (99.9%), and faster dynamic response (less than 20 min) compared to mainstream commercial membranes. Ultimately, we propose a semi-empirical model based on the operational characteristics of an electrolyzer equipped with composite membranes and predicting its matching behavior with dynamic renewable energy sources. This work explores the viability of manufacturing high-performance alkaline water electrolysis membranes for green hydrogen production under industrial conditions.

Abstract :
Phytate (PhA) holds considerable promise for constructing molecular sieve membranes due to its high density of long-range electrostatic attractions, customizable charge density, and excellent polymer affinity. Herein, PhA-Fe3+ complexes constructed by controllable coordination assembly are presented, based on metal-organophosphorus biphasic interfacial coordination reactions, and use the PhA-Fe3+ complexes to regulate the interfacial polymerization (IP) process to generate polyamide (PA) nanofiltration membranes. The PhA-Fe3+ complexes impart a high density of long-range electrostatic and short-range hydrogen bonding forces to the amine monomers and provide tunable charge densities through flexible metal-organophosphate coordination. Hydrogen bonding and strong electrostatic interactions spatially enrich the amine monomers and temporally slow down their diffusion into the hexane phase, as demonstrated by molecular simulations, resulting in a PA/PhA-Fe3+ membrane with increased surface area, enhanced microporosity, lower thickness, higher water density near pores, and nanoscale spotted structures. Those structures are recognized as the key factor in achieving a water permeance of 19.2 L m(-2) h(-1) bar(-1), alongside a MgCl2 rejection of 96.7% and a Li+/Mg2+ selectivity of 24.1 (Mg2+/Li+ mass ratio = 20), surpassing those of reported nanofiltration membranes. This PhA-Fe(3+ )complexes-modulated IP strategy offers fresh perspectives for constructing a highly permeable membrane for lithium extraction from salt lake brines.

Abstract :
Although conductive hydrogels have emerged as promising materials for developing highly flexible sensors in recent years, traditional hydrogels are prone to swelling, which significantly compromises sensor performance. To address this issue, a non-swelling hydrogel is prepared through a one-step radical polymerization of acrylic acid (AA), hydroxyethyl methacrylate (HEMA), tannic acid (TA), and quaternized chitosan (QCS) in aqueous water. The resultant poly(AA-HEMA)-QCS-TA (PAHCT) hydrogel features a highly crosslinked network, attributed to the formation of multiple hydrogen bonds among the abundant hydroxyl and carboxyl groups in AA, TA, and QCS, the electrostatic interactions between poly(AA-HEMA) and QCS, as well as polymer chain entanglements. This innovative architecture significantly enhances the anti-swelling ability of the PAHCT conductive hydrogel, achieving an equilibrium swelling ratio of 5.5% in water, along with remarkable tensile properties, reaching an elongation of 990%. Furthermore, the introduction of TA further improves the hydrogel's adhesion, ensuring its durability for long-term service. Consequently, strain sensors based on the non-swelling PAHCT hydrogel are capable of effectively monitoring human activities across various strain range and enabling reliable underwater communication. These findings open new avenues for the development of wearable sensors in amphibious environments, broadening the application scope of wearable electronics.

Abstract :
Highly permeable polyamide (PA) membranes with precise ion selection can be used for many energy-efficient chemical separations but are limited by membrane inefficiencies. Herein, polyphenol-mediated ZIF-8 nano- particles with hydroxyl-rich hollow structure were synthesized by tannic acid tailored regulation. PA-based membranes with fast penetration, high retention, and precise Cl-/SO42- selection were then synthesized through spatially and temporally controlling interfacial polymerization with modified ZIF-8 nanoparticles (tZIF8) as aqueous phase additives or as interlayers. The effects of the embedding position of tZIF-8 on the structure, morphology, physicochemical properties, and performance of PA-based membranes were explored through a sequence of characterization techniques. The results revealed that the PA-based membrane with tZIF-8 embedded in the PA layer could achieve a high water permeance of 24.8 L m- 2 h- 1 bar- 1 with a high retention of 99.4 % Na2SO4 and a Cl-/SO42- selectivity of 141, which was superior to most state-of-the-art PA-based membranes. Comparatively, the Cl-/SO42- selection of the PA-based membrane with tZIF-8 embedded between the PA layer and the substrate was 136, while the water permeance was slightly enhanced to 28.2 L m- 2 h- 1 bar- 1 . Excitingly, the resulting membranes all exhibit superior antifouling properties and stability. Our facile strategy for tuning membrane microstructures provides new ideals into the development of highly permeable and excellently selective PA-based membranes for precise ion sieving.

Abstract :
With the increasing demand in fields such as wearable sensors, soft robotics, tissue engineering, and wound dressings, the development of hydrogels with strong adhesion in wet environments has become a critical focus of research. However, most existing adhesive materials lack the ability to transition rapidly and reversibly between the adhesive and nonadhesive states, and their adhesion is often limited to a single wet environment. In this study, a smart interfacial adhesive hydrogel with tunable adhesion properties across diverse liquid environments is presented. By tailoring interchain interactions and leveraging electrostatically induced traction between hydrophilic and hydrophobic chain segments, the hydrogel achieves reversible adhesion modulation in response to temperature changes while maintaining strong wet adhesion. Notably, its adhesive strength at elevated temperatures (45 degrees C) is approximately three times greater than at lower temperatures (5 degrees C). The adhesive hydrogel exhibits an adhesive strength of 227 kPa in aqueous environments and 213 kPa in oil-containing environments. This innovative design strategy enables the hydrogel to exhibit broad switchable, and dynamic wet adhesion capabilities, unlocking significant potential for a wide range of applications.

Abstract :
In recent years, the demand for transparent substrates (e.g. windows, mirrors and photovoltaic glass) with anti- fogging performances has increased, while conventional anti-fogging coatings, like single-component organic coatings (PVA, PAA, PAAm), show poor stability and cannot maintain their performance stably under harsh environments. In this work, KH570@TiO2 plays the role of a bottom layer (KT coating) to increase roughness and binding, where the hydrolysis of KH570 anchors the substrate and provides active sites for the binding of the top coating, and the addition of the TiO2 enhances UV shielding properties. A composite PVA-AAm-POSS-NH2 gel (PAP coating) served as the top layer, which contains a large number of hydrophilic groups and thus endow the composite coating with satisfactory anti-fogging performance. The strong bonding force provided by the KT coating and the tight physical entanglement of the PAP coating endow the double-layer coating (PAPKT coating) stable anti-fogging performance (60 times of tape peeling test, 100 times of sandpaper friction test, and sand- punching test), and 48 s icing delay performance. The multi-performances make this work great potential in automotive glass as well as building facades to cope with complex situations.

Abstract :
The low light absorption capacity, fast recombination of photogenerated carriers and slow H+ reduction kinetics of carbon nitride severely limit its application in photocatalytic research. What's more, the challenge remains to efficiently utilise photogenerated electrons. In this work, sulfur (S) self-doped carbon nitride (SCN) was formed by thermal polymerisation, and the introduction of S stimulated the electron delocalisation of the active site and optimised the absorption of visible light by the carbon nitride. The introduction of defects and cyano (-C N) groups optimises the surface atomic and electronic structure of SCN, enhances photogenerated electron trapping and greatly suppresses charge recombination. The n-pi* electron jump of the lone pair of electrons at the defect site gives rise to a new absorption band that broadens the response to visible light. The H-2 evolution rate of SCNV under visible light reached 3437 mu mol g(-1) h(-1), which was about 3.0 times higher than that of SCN (1148 mu mol g(-1) h(-1)). Density Functional Theory (DFT) calculations further show that the introduction of defects and -C N lowers the energy barrier of *H, enhances carrier separation, and forms an electron-rich structure, which effectively promotes the utilisation of photogenerated electrons and photocatalytic H2 evolution efficiency.
