A portable system was presented, which directly harvests water from atmospheric moisture and generates energy using cellulose aerogels–high-entropy perovskite La(Cr_0.2Mn_0.2Fe_0.2Co_0.2Ni_0.2)O₃–lithium chloride (CA–LB5O3–LiCl). The system captures water from moist air during the night and facilitates solar-driven water evaporation and electrocatalytic water splitting during the day. The CA integrated with LiCl achieves efficient moisture absorption even in arid conditions due to its combined hydrophilic structure and entrapped water. The high-entropy perovskite LB5O3 promotes the lattice oxygen mechanism by weakening the metal–oxygen bond, resulting in an overpotential of 290 mV at 10 mA·cm⁻². Furthermore, its excellent solar absorption and photothermal conversion enhance water uptake to 1.01 g·g⁻¹ at 60% relative humidity (RH) as well as increase water evaporation rates to 2.1 kg·h⁻¹·m^–2. This process simultaneously generates O₂ and H₂ from moist airflow, providing both clean water and green fuel. This flexible and sustainable system offers a new pathway for producing water and energy in resource-scarce environments with potential applications in arid and remote regions.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 2","pages":"563 - 573"},"PeriodicalIF":17.2,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional wound dressings lack adaptability to the skin, and provide insufficient anti-leakage properties, failing to offer effective physical protection. Films composed of nano- or micro-fibers, due to their suitable softness and excellent deformation capabilities, are apt for wound repair. While electrospinning is employed to produce fibrous wound dressings, its complex procedures and the use of high voltage electric fields can impair the activity of bioactive molecules. In this study, we employed solution blow spinning to produce in-situ hybrids of hydrogenated styrene–butadiene–styrene (SEBS) block copolymer with Ag or TiO₂ nanoparticles for wound dressings. The SEBS polymer forms a closely fitting fibrous membrane on the skin surface via rapid solvent evaporation driven by high-speed airflow. This fibrous membrane demonstrates optimal hydrophobicity, breathability, ductility, and flexibility, aligning well with human skin, to ensure effective physical protection. Upon incorporation of Ag nanoparticles, the fibrous membrane displays robust antibacterial effects against methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) and <i>Escherichia coli</i> (<i>E. coli</i>). Evaluations of wound healing in MRSA-infected wounds, when compared to commercial Tegaderm™ films, show that the SEBS-based fibrous membranes effectively reduce infection, expedite wound closure, enhance collagen deposition, suppress the expression of inflammation-related cytokines and elevate the expression of angiogenesis-related cytokines, thus significantly promoting infected wounds.</p><h3>Graphical Abstract</h3><p>A solution blow spinning fibrous membrane was developed for the fabrication of in-situ wound dressings with high flexibility, ease of peeling off, waterproof nature, and prevention of blood penetration.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 2","pages":"528 - 540"},"PeriodicalIF":17.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Undesired durability and limited scale-up production capacity are the main obstacles to hinder the industrialized application of flexible EMI wearables. Here, a scalable Fe₃O₄/polypyrrole (PPy) embedded cotton/polypropylene (FP@CP) fabric is introduced for EMI shielding and Joule heating, which is achieved by a unique particle flow spinning method. This method can continually manufacture functional yarns in large quantities, followed by weaving into fabrics. The core-sheath yarn structure can highly embed Fe₃O₄/PPy shielding layer by polypropylene (PP) strips, which protects internal functional components from leakage or damage by the environment. Consequently, the obtained fabrics present greater durability (50 washing and 465 abrasion cycles) in comparison with most reported EMI devices. The EMI shielding mechanism was investigated through both experimental and simulation methods. It suggests that the combination of EMI reflection and absorption modes synergistically contributes to enhancing the EMI shielding property of obtained fabrics, reaching a maximum total shielding effectiveness (SE_T) of 47 dB. Besides, the composite fabric achieves a high Joule heating temperature to 105 ℃ at 3 V within 10 s due to its efficient electric-thermal property. This work paves a cost-effective way to realize scale-up manufacturing of versatile EM protection textiles to be applied in daily, military and aerospace fields.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"7 2","pages":"513 - 527"},"PeriodicalIF":17.2,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graphene, which is known for its outstanding mechanical and electrical properties, has shown great application potential as a sensor material. However, its durability and performance consistency in practical applications still require enhancement. In this study, magnetic graphene fibers (MGFs) are prepared via wet spinning, using graphene oxide (GO), doped with Fe₃O₄ nanoparticles. The resulting MGFs exhibit a high tensile strength of 58.6 MPa, a strain of 5.3% and an electrical conductivity of 1.7 × 10⁴ S/m. These MGFs are utilised to construct a multilayer fabric for fabrication of flexible pressure sensors. The confinement within the spinning channel facilitates an ordered arrangement of GO sheets, resulting in MGFs with superior electrical and mechanical properties. The issuing MGFs pressure sensors demonstrate a wide detection range (0–120 kPa), high sensitivity (0.233 kPa⁻¹, 0–40 kPa) and rapid response/recovery times (121 ms/158 ms). In addition, it exhibits a remarkable durability, maintaining performance over 1300 cycles, during continuous operation, with negligible degradation.

The synthesis was based on electrospinning of supramolecular micelles, which were stretched under hydrodynamic forces and self-assembled as in oriented and ordered form. Ordered mesoporous carbon nanofibers (OMCNFs) were obtained after removing the micelle template. The aligned mesopores over electrode scale strongly accelerate diffusion kinetics. The OH⁻ ion diffusion coefficient of OMCNF is 26 times larger than that of the nanofiber with non-ordered pores (NMCNF) and 206 times larger than that of Pt/C. As a result, the electrocatalytic performance of OMCNF was maintained at increased catalyst loadings, while performance deterioration was observed in NMCNF and Pt/C.

Wet electrospinning replaces the traditional solid collector with a liquid coagulation bath, which can yield fibers with porous, bending, and twisting structures. In addition, the fiber surface can be modified and functionalized to prepare continuous nanofiber yarn, which considerably improves the performance of electrospun fibers in some applications. Wet electrospinning promotes the industrial production of electrospun fibers in the textile fields.

Smart heat-moisture management textiles can effectively regulate heat-moisture comfort between the environment and skin, greatly reducing energy consumption; these results are in line with sustainable development goals. In this work, a skin-inspired adaptive heat-regulating fabric based on heat-responsive shape-memory ethylene vinyl acetate copolymer fibres and traditional cotton fabric is used. Furthermore, single-sided hydrophobic finishing is introduced to provide the fabric with unidirectional moisture transport. Owing to the shape memory effect, the smart fabric has an environment-adaptive and responsive dynamic structure in the form of a heat-induced gap opening and cool-induced gap closing. As a result, the heat conductivity of the smart textile can be switched from 0.086 to 0.089 W/m·K. Moreover, the air permeability and moisture evaporation can be regulated between 443.5 mm/s, 1761.81 g/(d·m²) and 461.7 mm/s, 1963.8 g/(d·m²), reversibly and repeatedly; the unidirectional moisture transport capacity with a unidirectional moisture index of 193.2 can also be regulated to synergistically improve the heat-moisture comfort, and the entire process results in zero carbon emission. Moreover, we demonstrate the application of the smart adaptive fabric in heat-moisture management fields, attaining a cooling effect of 4.35 °C and a breathability difference of 89.6 mm/s; these values correspond to more than 30% building cooling and heating energy savings, and these results are in line with the sustainable and zero-carbon trends.
