Significant research efforts have been dedicated to fiber component modulation and microstructure design toward enhancing the effective absorption bandwidth and the dissipation of EMWs. This review summarizes the recent developments in EMW-absorbing fibers, including their absorption mechanisms, preparation methods, performance optimization and structural design. For inorganic EMW-absorbing fibers, their inherent dielectric properties allow the matrix to absorb EMWs, while doping with additional components further enhances impedance matching. In contrast, organic fibers, which generally lack intrinsic EMW-absorbing capabilities, require hybridization with various organic or inorganic functional materials and structural modifications to optimize EMW-absorbing performance. Finally, emerging trends and ongoing challenges in the development of EMW-absorbing fibers are discussed, with the goal of promoting their practical applications.

In this regard, developing an effective method to facilitate rapid hemostasis and treat infected wounds is of significant importance and value. In this study, we developed a novel strategy for the one-step manufacturing and crosslinking of gelatin (Gel)/<i>Polygonum sibiricum</i> polysaccharide (PSP) bioactive nanofibrous sponge through electrospinning with a homemade liquid vortex collector. Attributed to the addition of a specific ratio of tannic acid (TA) in the electrospinning solution, the resulting gelatin-tannic acid-<i>Polygonum sibiricum</i> polysaccharide (GelTa-PSP) nanofibrous sponges can be in-situ crosslinked during the electrospinning process and easily collected in the expected shape and size, without the need for any toxic crosslinking agent for post-treatment. We demonstrate that GelTa-PSP nanofibrous sponges possess excellent water absorption and hemostatic properties, adequate antimicrobial activity, and favorable biocompatibility. Specifically, the GelTa-PSP nanofibrous sponges encourage blood cell adhesion and exhibit strong hemostatic capabilities. In comparison to medical gauze, the GelTa-PSP nanofibrous sponges provide effective procoagulant function and hemostatic impact in rat tail-breaking and liver injury models. Moreover, due to the bioactivity of Chinese herbal medicine flavonoid polysaccharides, the GelTa-PSP nanofibrous sponges demonstrated enhanced performance in wound healing of infected rats.

Optimizing electroactivity at the interface between dental implants and tissue is essential for enhancing integration and preventing bacterial invasion. Here, a bioinspired piezoelectric-conductive integrated peri-implant gingiva (PiG) with simultaneously enhanced antibacterial efficacy and soft-tissue integration, which is based on a flexible piezoelectric film and conductive polymer network, is presented. The piezoelectricity of PiG is achieved through the electrospinning of polyvinylidene fluoride/BaTiO₃/MXene on a polydopamine-modified plasma-activated Ti surface, whereas the conductive property of PiG is achieved by the in situ polymerization of 3,4-ethylenedioxythiophene monomers. Under ultrasonic irradiation, PiG can promote the formation of neutrophil extracellular traps and reactive oxygen species, thus achieving synergistic and efficient piezodynamic killing of <i>Staphylococcus aureus</i> (<i>S. aureus</i>) and <i>Escherichia coli (E. coli)</i>. Additionally, piezoelectricity-enabled electrical stimulation endows PiG with enhanced fibroblasts adhesion, proliferation, and collagen secretion. As a demonstration, ultrasound irradiation of PiG-grafted Ti implanted in a subcutaneous implantation rat model efficiently eliminates the <i>S. aureus</i> infection and rescues the implant with increased soft-tissue integration. The concept of an artificial PiG is anticipated to open new avenues for the development of high-performance implant materials, potentially extending their lifespans.</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 4","pages":"1128 - 1147"},"PeriodicalIF":21.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169103","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, optimized membranes (C-NFO@GDY) are synthesized with a uniform honeycomb nanostructure of graphdiyne (GDY) on flexible coal-based preoxidized fibers (C-NFO) through the Glaser‒Hay coupling reaction. The honeycomb nanostructure of GDY effectively disperses external stress on the C-NFO fibers, increasing the tensile strength from 2.8 to 3.2 MPa. In addition, the nanostructure enhances hydration layer formation kinetics, achieving superhydrophilicity (0°) and underwater superoleophobicity (&gt; 150°) of the membrane. When tested against three surfactant-stabilized emulsions (cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS), and polyoxyethylene sorbitan monooleate (Tween 80)), the membranes demonstrated separation fluxes of 2936 L/(m² h), 2149 L/(m² h), and 1855 L/(m² h), and the corresponding separation efficiencies were 99.6%, 96.6%, and 93.1%. For CTAB-stabilized emulsions, the C-NFO@GDY membrane (zeta potential: − 65.2 mV) exhibits strong electrostatic attraction with cationic surfactants, achieving a high flux of 2936 L/(m² h) and a separation efficiency of 99.6%, surpassing those of recently reported MXene and PANI composites under identical conditions. Overall, the synergy between honeycomb nanostructure and electronegativity of GDY overcomes the flux–efficiency trade-off, offering new ideas for the preparation of oil–water separation membranes.</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 4","pages":"1195 - 1207"},"PeriodicalIF":21.3,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167832","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}

However, achieving structural robustness and multifunctionality in thermal regulation remains a persistent challenge for TENG-based skin electronics. This deficiency compromises the charge transfer efficiency and diminishes user comfort during prolonged wear. This study introduces a novel thermally regulating triboelectric nanogenerator (TR-TENG) in the form of a bilayer electronic textile (e-textile) fabricated through a semi-bonding assembly approach. The e-textile comprises two distinct layers: nonwoven styrene-ethylene-butylene-styrene (SEBS) textiles loaded with highly reflective and electronegative polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) nanoparticles (NPs) and polyvinyl alcohol (PVA) fibers embedded with emissive and electropositive SiO₂ NPs. These layers are merged via hot-press needle punching, creating a flexible, permeable yet robust interface capable of dual functionalities—enhanced solar reflection and efficient infrared emission—while maintaining stable triboelectric performance. When utilized as a skin-attachable self-powered motion sensor, this e-textile provides a remarkable passive radiative cooling effect and high-fidelity recognition of both high-frequency and subtle motions (swallowing, running, breathing, etc.).
