Fiber electronics discretely integrated into daily life is taking center stage for its enormous potentials for healthcare, physiological monitoring, and human-machine interfaces. However, the state-of-the-art fiber electronics are remarkably distinguished from generic fibers in diameter, stiffness, smoothness, and productivity. Here, we developed a universal scalable manufacturing process and generic fiber-like fine and soft self-powered interactive electronics with a diameter of only dozens of μm and a continuous length of hundreds of kilometers. These fiber electronics are prepared with a large-scale manufacturing speed (>20 m/min), and adapt to modern textile technology including weaving, knitting, sewing and embroidering. Moreover, Kawabata evaluation system for fabrics was systematically employed to analyze the fiber electronics enabled e-textile’s sensorial comfort, suggesting that adding the fiber electronics to fabric benefits its tactile sensations (e.g., softness, fluffy and fullness). Based on tribotronics, the interactive fiber electronics-based smart clothing demonstrates versatile applications including biomechanical energy harvesting , vital signal detecting, human motion recognizing and tactile sensing.

Waterproof and breathable membranes that provide a high level of protection and comfort are promising core materials for meeting the pressing demand for future upscale protective clothing. However, creating such materials that exhibit environmental protection, high performance, and ease of fabrication has proven to be a great challenge. Herein, we report a novel strategy for synthesizing fluorinated polyurethane (C6FPU) containing short perfluorohexyl (-C6F13) chains and introduced it as hydrophobic agent into a polyurethane (PU) solution for one-step electrospinning. A plausible mechanism about the dynamic behavior of fluorinated chains with an increasing C6FPU concentration was proposed. Benefiting from the utilization of magnesium chloride (MgCl2), the fibrous membranes had dramatically decreased maximum pore sizes. Consequently, the prepared PU/C6FPU/MgCl2 fibrous membranes exhibited an excellent hydrostatic pressure of 104 kPa, a modest water vapor transmission rate of 11.5 kg m–2 d–1, and a desirable tensile strength of 12.4 MPa. The facile fabrication of PU/C6FPU/MgCl2 waterproof and breathable membranes not only matches well with the tendency to be environmentally protective but also fully meets the requirements for high performance in extremely harsh environments.

The fabrication of PTFE micron filaments with superior mechanical properties remains both a key research focus and a considerable challenge in the field of engineering technology. In this study, the PTFE micron filaments were successfully prepared via wet spinning and molding process by optimizing the concentration of the carrier polyethylene oxide (PEO) aqueous solution, molecular weight of the coagulation bath poly-(ethylene glycol) PEG, mass ratio of PTFE to PEO, and sintering temperature. Due to its higher hygroscopicity and surface tension compared to the spinning solution, PEG provided favorable conditions for the solidification of the PTFE/PEO primary filaments. Elemental analysis results confirmed the complete removal of PEO and PEG from the PTFE fibers after sintering. When the mass fraction of PEO is 4%, the mass ratio of PTFE to PEO is 4:1, PEG molecular weight is 200 Da, and the sintering temperature is 370 ℃, the resulting PTFE fibers display a smooth and compact Surface, with a diameter of 27.50 ± 0.66 μm. Furthermore, tensile testing reveals that the PTFE filaments achieved a tensile strength of 133.02 ± 5.39 MPa and an elongation at break of 567.77 ± 93.67%. These findings demonstrate a feasible and efficient approach for the fabrication of high-performance PTFE micron filaments.

Since the main solvent of waterborne polyurethane (WPU) is water, its water resistance is poor. Additionally, the low oxygen index of WPU adhesive films limits their flame-retardant efficacy as coatings, thereby restricting their application scope. To address these limitations, this study independently modified the hydrophobicity and flame retardancy of WPU. First, a cyclophosphonitrile derivative (HCCP-6) was synthesized as a flame retardant. Flame-retardant WPU (NPWPU) was then prepared by reacting the –NH 2 group of HCCP-6 with the –NCO group of a polyurethane prepolymer, incorporating the flame-retardant properties into the WPU polymer chain via free-radical grafting. Next, hydrophobic F-SiO 2 suspensions were prepared and combined with NPWPU emulsions of varying concentrations. The mixtures were sprayed onto cotton fabrics using an airbrush to produce waterproof, flame-retardant polyurethane-coated textiles. Results demonstrated that NPWPU/F-SiO 2 -coated cotton fabrics exhibited water contact angles exceeding 150°, indicating excellent hydrophobicity. These fabrics also showed increased char residue, reduced total heat release, and suppressed smoke production. This performance stems from the synergistic flame-retardant effect of nitrogen (N) and phosphorus (P), coupled with the high-temperature resistance of SiO 2 , which promotes char formation, shields the material’s inner layers from thermal degradation, and enhances overall flame retardancy.

To realize the effective electromagnetic (EM) protection, the demand of large-scale production and desirable flexibility for metamaterial absorber (MA) has been a hotspot. In this work, a flexible MA with the characteristics of textile textured meta -surface, dielectric lossy layer and temperature-strengthened reflective layer is prepared by means of chemical plating and laser-induced graphene (LIG) techniques. Co-Ni metallized CNTs and PEDOT:PSS are combined to form magneto-dielectric synergy for attenuation in medium layer, and the superiorities of fabric as substrate to enhance EM absorption in top layer is validated. The structural parameters of MA are optimized via CST stimulation, and the as-prepared MA exhibits a minimum reflection loss (RL) of −26.4 dB and an effective absorption band (EAB) of 8.0 GHz, with the radar cross section (RCS) bandwidth of 7.4 GHz in the X band (2–18 GHz), delivering a promising potential for radar stealth.

2-Nonenal, a primary component of the characteristic “aging odor,” poses minimal toxicity but significantly affects quality of life and psychological well-being, necessitating its effective removal. However, the existing removal methods mainly rely on adsorption of activated carbon or odor masking after diffusion, which suffers from low efficiency and environmental concerns. This study presents an approach for eliminating 2-nonenal through a multilayered composite textile system that integrates the synergistic effects of amine-based adsorption and triboelectric-driven mechanisms, transforming waste static electricity into valuable resources. Manganese oxide particles were loaded onto the surface of PET by hydrothermal method (250.5 g/m2), and then modified by amination, and then combined with other different common fabrics to form double-layer composite fabric. Under 2 Hz friction frequency, interfacial contact electrification generates substantial surface charges up to 40 nC/cycle, with electrostatic effects enhancing catalytic performance through three synergistic mechanisms: (1) Continuous tribo-induced charge injection drives valence state oscillations in manganese oxides, concurrently generating dual reactive oxygen species (•O2– and •OH); (2) Locally intensified electric fields from accumulated interfacial charges significantly reduce activation energy for aldehyde group oxidation; (3) Amino-manganese oxide charge transfer complexes accelerate regeneration of high-valent manganese through electron-bridging effects, achieving 9% improvement in catalytic cycle efficiency. This electrocatalytic coupling mechanism achieves sustained 87.77% removal efficiency for 2-nonenal, providing an innovative self-powered and energy-efficient strategy for aldehyde pollutant remediation.
