However, currently reported radiative cooling materials primarily focus on hydrophobic polymer films, inevitably leading to sweat accumulation and limited cooling efficiency in hot-humid environments. Herein, an advanced Janus membrane with excellent temperature–moisture management capabilities is developed, which combines radiative cooling and evaporative heat dissipation. Modification with Calcium sulfite (CaSO₃) nanoparticles not only enhances the optical properties (state-of-the-art solar reflectance of 96.6%, infrared emittance of 96.1%) but also improves the wettability of the polylactic acid fiber membrane. Especially 15% emittance improvement is achieved due to the strong infrared radiation ability of CaSO₃. The membranes with opposite wettability realize the directional sweat transport (high one-way transport index of 945%). Excellent radiative cooling capability is demonstrated with sub-ambient cooling of 5.8 °C in the dry state. The Janus membranes covering sweaty skin exhibit a 46% shorter drying time and a 2 °C lower average evaporation temperature compared to cotton fabric, indicating highly efficient thermal and moisture management. This work provides an efficient route to achieving smart textiles that enable the human body to adapt to complex environmental conditions.</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":"6 6","pages":"1765 - 1776"},"PeriodicalIF":17.2,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141640255","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}

The key lies in precise diameter control and industrial manufacturing with a straightforward, energy-saving, and efficient strategy. Herein, we introduce a hydrodynamic drafting spinning platform inspired by water vortices. It employs the rotation of a nonsolvent to generate vortices and further facilitate the efficient drafting of hydrogel fibers. Through supporting equipment, we have achieved impressive results, including scalable production capabilities (1 h, single channel output of 2 × 10³ m of fibers) and extensive adaptability. Subsequently, by simply regulating the velocity difference between fiber extrusion and fluid vortex, hydrogel fibers can be drafted to any diameter from about 1 mm to 5 × 10^–2 mm (for chitosan system). Notably, this platform endows hydrogel fibers to carry functional hydrophilic or hydrophobic drugs. Equally significant, these delicate hydrogel fibers seamlessly integrate with subsequent manufacturing technologies. This allows the production of various end products, such as fiber bundles, yarns, fabrics, and nonwovens. Furthermore, the immense potential in biomedical applications has been demonstrated after obtaining hydrogel fiber-based nonwoven as wound dressings.

However, the weak interface between the conductive materials and elastic substrates restricts fibers flexibility under strain, leading to challenges in achieving both linearity and sensitivity of the as-prepared fibrous strain sensor. Herein, cryo-spun drying strategy is proposed to fabricate the thermoplastic polyurethane (TPU) fiber with anisotropic conductive networks (ACN@TPU fiber). Benefiting from the excellent mechanical properties of TPU, and the excellent interface among TPU, silver nanoparticles (AgNPs) and polyvinyl alcohol (PVA), the prepared ACN@TPU fiber exhibits an outstanding mechanical performance. The anisotropic conductive networks enable the ACN@TPU fiber to achieve high sensitivity (gauge factor, <span>(GF)</span> = 4.68) and excellent linearity within a wide working range (100% strain). Furthermore, mathematical model based on AgNPs is established and the resistance calculation equation is derived, with a highly matched fitting and experimental results (<span>(R^{2})</span> = 0.998). As a conceptual demonstration, the ACN@TPU fiber sensor is worn on a mannequin to accurately and instantly detect movements. Therefore, the successful construction of ACN@TPU fiber with anisotropic conductive networks through the cryo-spun drying strategy provides a feasible approach for the design and preparation of fibrous strain sensing materials with high linearity and high sensitivity.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 6","pages":"1898 - 1909"},"PeriodicalIF":17.2,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568920","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}

Herein, we constructed multidimensionally nano-topologized electrospun polycaprolactone (PCL) fibrous membranes with shish-kebab nanoarrays on each fiber through self-induced crystallization, on which the CuO₂–MgO₂ bimetallic peroxide nanodots (BPNs) were anchored by polydopamine (PDA) as the bridging layer. When activated by the acidic microenvironment (typically infected diabetic wound), BPNs on fibers reacted immediately to release Cu²⁺ and Mg²⁺ ions together with hydrogen peroxide (H₂O₂) molecules, which were then transferred into ·OH radicals through Fenton-type reactions catalyzed by Cu²⁺ for instant bacteria elimination. At the same time, the released Cu²⁺ and Mg²⁺ ions were retained to improve the angiogenesis and suppress the inflammation infiltration, thus remodeling the wound microenvironment. Meanwhile, the one-dimensional (1D)-constructed nano shish-kebabs and PDA coating on fibers provided additional topological activation for cell adhesion and directed migration along the aligned fiber orientation. Through the meticulous design, the resultant membranes markedly accelerated the infected wound healing in the diabetic rat model.

However, current fabrication methods for these structures primarily rely on chemical deposition, often resulting in undesirable material structures and necessitating the use of additives, which can degrade the electrochemical performance of such structures. Herein, physically deposited TMO nanoribbon yarns generated via delamination engineering of nanopatterned TMO/metal/TMO trilayer arrays are proposed as potential high-performance FSs. To prepare these arrays, the target materials were initially deposited using a nanoline mold, and subsequently, the nanoribbon was suspended through selective plasma etching to obtain the desired twisted yarn structures. Because of the direct formation of TMOs on Ni electrodes, a high energy/power density and excellent electrochemical stability were achieved in asymmetric FS devices incorporating CoNixOy nanoribbon yarns and graphene fibers. Furthermore, a triboelectric nanogenerator, pressure sensor, and flexible light-emitting diode were synergistically combined with the FS.

Hence, the synergy of the physical modification methods is achieved by incorporating BaTiO₃ (BTO) nanoparticles (NPs) into the PVDF. By functionalizing BTO NPs with polydopamine, the TENG performance is further improved owing to the enhanced dispersion of NPs and improved crystallinity of the PVDF chains.
