Abstract ：
Conductive hydrogels have great potential in flexible electronics due to their flexibility, excellent biocompatibility and diverse functionalities. However, most rapid-gelation hydrogels tend to manifest weak and fragile due to vigorous reaction process and poor adaptability in cryogenic environment, which severely impede their practical applications. Herein, a facile and mild strategy for rapid gelation is proposed that accelerates polymerization by generating reactive oxygen radicals via electron transfer based on the excitation of ferric phytate ligands under UV irradiation, which takes only 17 s to initiate. Interestingly, the introduced phytic acid imparts the hydrogel excellent electrical conductivity (12 ms/cm), frost resistance (- 31celcius) and improves tensile properties (elongation at break 1299 %). The hydrogel that combines the above merits inspires the construction of strain sensor for monitoring physiological activity of low-temperature environments. This study provides a simple and universal approach for the rapid preparation of antifreeze hydrogels and reinforces the focus on sustainable and high-value utilization of phytic acid in advanced applications.

Abstract ：
Plastics, accumulating globally as microplastics in living organisms, significantly contribute to environmental issues. Current materials like polylactic acid and commercial paper face limitations due to inadequate heat and water resistance, resulting in various practical inconveniences. This study reports a high-strength, water-resistant, recyclable, and naturally degradable pure cellulose food packaging material, which is crafted from bacterial cellulose (BC) and ethyl cellulose (EC) by a straightforward filtration and scratch coating process. The use of the EC ethanol solution eliminates the need for additional binders. Remarkably, the EC-BC pure cellulose material exhibits excellent mechanical properties (tensile strength of 195.3 ± 23.2 MPa), a stability in liquid environments (136.9 ± 24.2 MPa mechanical strength after 30 minutes of immersion in water), recyclability, natural degradability, cost-effectiveness, and non-toxicity. These attributes position binder-free hybrid designs, based on cellulose structures, as a promising solution to address environmental challenges arising from the extensive use of single-use plastics. © 2024 The Author(s)

Abstract ：
Airborne pollution, derived from tiny particulate matter (PM) and the pandemic virus, strongly stimulates the demand for personal protective materials but also causes serious environmental issues due to the mass discarding of disposable nondegradable face masks. Despite a few reports of bio-based filters, however, it remains a challenge to develop biodegradable respirators with efficient, wet-stable PM0.3 filtration and low pressure drop. Herein, the degradable multi-scale fibrous filter composed of polylactic acid (PLA) micro-/submicron-fibers and bacterial cellulose (BC) nanofibers was rationally designed to balance the filtration efficiency and resistance. The 2D BC nano-mesh with the small pores was self-assembled by the electro-spraying technique and the PLA submicron-fibrous networks with medium pores were prepared by the electrospinning technology. The multilayer micro-/submicron-/nano-fiber construction endowed the membrane with a low pore size of 1.27 mu m and also extended the particle flow path, which contributed to the efficient and durable PM0.3 interception. As a result, the prepared filter showed over 99.89% PM0.3 filtration efficiency but a low pressure drop of 104 Pa. More significantly, it still presented over 99.68% PM0.3 removal after long-term filtration under 90% RH. This work may provide meaningful guidance for the development of biodegradable high-protective air filters.

Abstract ：
Organic solvent nanofiltration (OSN) is a green, energy-saving, and highly efficient emerging membrane separation technology, and there is an urgent need for robust, easy-to-process OSN membranes with high permeance and small solute selectivity for industrial applications. Herein, we propose a new strategy for accurately designing novel OSN membranes. Specifically, a polyamide (PA) interlayer was synthesized in-situ on the surface of homogeneous reinforced poly(p-phenylene terephthamide) (PPTA) hollow fiber membrane by interfacial polymerization (IP) using both ultra-low concentrations piperazine (PIP, 0.05 wt%) and trimesoyl chloride (TMC, 0.005 wt%), and then a defect-free and dense PPy layer was deposited on top of the hydrophilic PA interlayer by chemical vapor deposition (CVD) process to prepare PA/PPy composite membranes with spherical cluster or strip cluster "Turing-like" structure. The resulting PA/PPy composite membranes presented an excellent high selective permeability, the dimethylacetamide (DMAc) permeability was 21.1 Lm(-2)h(-1)MPa-1, and the molecular weight cut-off (MWCO) was as low as 185 Da. A 30-hour OSN test at elevated temperatures (80 degrees C) and in organic solvent (DMAc), as well as a one-month immersion test in ethanol and DMAc at room temperature, demonstrated superior separation performance and structural stability of the membranes, indicating their application potential in harsh solvent systems. Our novel method for developing nanoscale ordered structured PA/PPy composite membranes offers great potential for the development of multilevel structural designs in the preparation of high-performance OSN membranes with potential industrial applications.

Abstract ：
Polyphenylene sulfide (PPS), commonly used as a core material for high -temperature flue gas treatment, exhibits elevated viscosity when processed even at temperature exceeding 280 degrees C. In this study, a novel high-flowability PPS -based composite was fabricated through the incorporation of graphitic carbon nitride (g-C3N4) via a wellestablished melt extrusion procedure. The enhancement of flowability in PPS was verified, and the material's texture structures and fundamental properties of composites with varying contents were determined. The composites exhibit well -dispersed g-C3N4, a significant reduction in shear viscosity (>10 %), a notable increase in melt index (>30 %), improved crystallinity, and comparable or superior performance compared to pure PPS. When the g-C(3)N(4 )was introduced into the PPS matrix, a phase -separated composite structure was formed. This structure reduces the entanglement degree between the PPS molecular chains and provides more space for freemovement of the PPS chains, and thus the improvement in flowability for the composites can be clearly demonstrated. Therefore, g-C(3)N(4 )can be used as a novel flow modifier to enhance the flowability and stability of PPS resin without compromising its fundamental properties, which offers significant prospects for improving productivity, optimizing energy usage, and managing costs for PPS -based products.

Abstract ：
Durable superhydrophobic anti-erosion/anticorrosion coatings are highly demanded across various applications. However, achieving coatings with exceptional superhydrophobicity, mechanical strength, and corrosion resistance remains a grand challenge. Herein, a robust microstructure coating, inspired by the cylindrical structures situated on the surface of conch shell, for mitigating erosion and corrosion damages in gas transportation pipelines is reported. Specifically, citric acid monohydrate as a pore-forming agent is leveraged to create a porous structure between layers, effectively buffering the impact on the surface. As a result, the coating demonstrates remarkable wear resistance and water repellency. Importantly, even after abrasion by sandpaper and an erosion loop test, the resulting superhydrophobic surfaces retain the water repellency. The design strategy offers a promising route to manufacturing multifunctional materials with desired features and structural complexities, thereby enabling effective self-cleaning and antifouling abilities in harsh operating environments for an array of applications, including self-cleaning windows, antifouling coatings for medical devices, and anti-erosion/anticorrosion protection, among other areas.

Abstract ：
Real-time monitoring of respiration plays a very important role in human health assessment, especially in monitoring and analyzing respiration during exercise and sleep. However, traditional humidity sensors still have problems in flexibility, sensitivity, and durability, so there is an urgent need to develop humidity sensors with high sensitivity, stretchability, and environmental resistance as respiratory monitoring applications. Here, based on the double network hydrogel structure of polyvinyl alcohol and polyacrylamide, a highly sensitive, highly stretchable, and environmentally stable organic hydrogel humidity sensor has been manufactured by using the synergistic effect of lithium chloride and MXene. The hydrogel humidity sensor shows rapid response in the humidity range of 40-85% RH, and has a high sensitivity of -103.4%/% RH. In addition, it exhibits more than 3000% mechanical strain and excellent environmental resistance, which is attributed to the chemical cross-linking in the hydrogel network and the synergistic effect of multiple hydroxyl groups in glycerol forming rich hydrogen bonds with water and polymer chains. The hydrogel humidity sensor is used for real-time monitoring of breathing and sleep processes. This work provides a new strategy for preparing high-performance, extensibility, and environmental stability hydrogel-based sensors for respiratory monitoring. Based on the double network hydrogel structure of polyvinyl alcohol and polyacrylamide, an organic hydrogel humidity sensor with high sensitivity, high tensile property, and environmental stability is prepared by the synergistic action of lithium chloride and MXene. The potential application of hydrogel sensor in the field of respiratory monitoring is presented. image

Abstract ：
Hard carbon with abundant resources, low-cost, and high specific capacity, is a promising anode material for large-scale sodium-ion batteries. However, the poor rate performance of hard carbon suffers from serious challenges due to sluggish ion transport dynamic behavior, especially at low potential, in high power density of sodium-ion batteries. To address this issue, we introduce an ionic-conductive sodium-titanate into hard carbon to boost its sodium-ion transport kinetics via constructing a dual ionic-electronic conducting network in hard carbon anode. Benefiting from our design, the optimized hard carbon-sodium titanate electrode achieves high specific capacity of 137 mAh g(-1) at a high current density of 10 A g(-1), compared to that of hard carbon of 25 mAh g(-1) at 10 A g(-1). Remarkably, it also exhibits an excellent capacity retention of 71.4% at the current density of 2.0 A g(-1) after 800 cycles. This work presents a practical strategy for high-rate hard carbon design and provides valuable insights into the construction of high-rate anode for advanced sodium-ion batteries.

Abstract ：
The membrane fouling derived from the accumulated dust pollutants and highly viscous oily particles causes irreversible damage to the filtration performance of air filters and results in a significant reduction in their service life. However, it is still challenging to construct high-efficiency and antifouling air filtration membranes with recyclable regeneration. Herein, the fluorine-free amphiphobic micro/nanofiber composite membrane was controllably constructed by integrating click chemistry reaction and electrospinning technique. Low-surface-energy fibers were constructed by a thiol-ene click chemical reaction between mercaptosilane and vinyl groups of polystyrene-butadiene-styrene (SBS), combined with hydroxyl-terminated poly(dimethylsiloxane) during the electrospinning process. The functional air filter is then prepared by the two-layer composite strategy. Because of the advantages of liquid-like fibrous surface and micro/nanofibrous porous structure, SBS/PAN composite membrane simultaneously shows superior antifouling performances of pollutants and filtration efficiency of over 97% PM0.3 removal. More importantly, the antifouling fibrous membrane still presents a stable and efficient filtration efficiency after multiple washes. Its service life in dust filtration environments is approximately 1.7 times longer than that of the substrate membrane. This work may provide a significant reference for the design of antifouling fiber membranes and high-efficiency air filters with long life spans and reusability. © 2024 American Chemical Society.

Abstract ：
Herein, Co-MoSx/CN photocatalysts were prepared by photodeposition using urea and ammonium tetrathiomolybdate as starting materials. The doping of the cocatalyst MoSx changed the electronic band structure of CN, shortened the band gap width, and exhibited excellent visible light response. Furthermore, the introduction of the transition metal Co not only forms a Co-Mo-S bond but also makes better use of the excess S2- generated by the decomposition of ammonium tetrathiomolybdate, resulting in more active sites and improving the utilization of raw materials.
