Alternating current electroluminescent (ACEL) devices have become an important direction for the development of visualized smart wearable e-textiles due to their advantages of light weight, flexibility, easy integration, and convenient processing. The electrode layer is a crucial component of ACEL devices, providing the necessary electric field for the dielectric and luminescent layers, and facilitating the stable transport and recombination of electrons and holes in the luminescent layer. Herein, the structural design principles and luminescence mechanisms of ACEL are reviewed, and the newest research and remarkable results of metal-, carbon-, and ion-gel-based electrodes are introduced. This review emphasizes that optimizing the conductive pathways of electrodes, enhancing the interfacial roles of functional layers, and adjusting the thickness and microstructure of layers are crucial for developing high-brightness and stable ACEL devices. Also, increasing the electric field strength and selecting high dielectric constants are identified as key factors. On this basis, the recent progress of ACEL fibers, films, and fabrics in textiles is highlighted. Finally, the challenges and growth encountered in the development of ACEL devices are prospected, considering aspects such as voltage, luminous brightness, color, sensitivity, comfort, and large-scale processing. © 2025 The Royal Society of Chemistry.

This paper reports the effects of fiber breakage defects and waviness defects on the compressive fatigue behavior and the progressive damage evolution process of 3D Multiaxial Braided Composites (3DMBCs). Combined with finite element compression simulation and ultra-depth microscope, the internal defect content of composites with different braiding angles was determined. The results demonstrate that the weakening effect of waviness and fiber breakage defects is greater than the strengthening effect of the braiding angle. This causes the fatigue resistance of 3DMBCs with the 31° braiding angle being better in both directions of 0° and 90°. The increase of 4° waviness and 10% fiber breakage defect results in the average fatigue life of composites being shortened by 48% and the energy consumption rate increased by 10% at 85% stress level in 90° compression direction. The alteration in loading direction modifies the included angle corresponding to the stress component. The stress component parallel to the fiber direction under compressive fatigue load leads to interfacial debonding in the composites, whereas the stress component perpendicular to the fiber direction results in pronounced shear failure.

引用

International Journal of Biological Macromolecules 2025年 310卷 142920页

作者： Hao, Kexin Xue, Ying Li, Bo Liu, Huijing Shen, Guodong Wu, Hailiang Yao, Yijun School of Textile Science and Engineering Xi'an Polytechnic University Shaanxi Xi'an710048 China Key Laboratory of Functional Textile Material and Product Xi'an Polytechnic University Ministry of Education Shaanxi Xi'an710048 China

In this work, we provided a new method for preparing cellulose-keratin (CK) polymer by "thiol-ene" click reaction. Firstly, the allyl cellulose (AC) was prepared in alkali/urea system, and then C[dbnd]C double bond of AC was reacted with -SH of keratin (Ker) to produce CK polymer under UV irradiation. FTIR, XRD, XPS, and NMR provided the evidences for producing AC and CK, and the integrity of the keratin polypeptide chain could be preserved. CK polymer showed ease-to-process performance, and the composite film formed by casting showed the characteristics of high transmittance, dense cross-section morphology, and easy to twist, bend, and fold. The breaking strength and elongation at break of CK film could reach 44.93 MPa and 22 %, respectively, which exceeded that of the cellulose-protein polymer films obtained by cross-linking with epichlorohydrin in our previous work. The breaking strength and elongation at break of CK fiber formed by wet-spinning could reach 28.8 MPa and 15 %, respectively, which exceeded that of cellulose/keratin composite fiber formed by the co-solvent ionic liquid. Interestingly, the CK fiber exhibited excellent moisture absorption and could be equipped with other functions such as fluorescence, thermochromic, and flame retardancy, which is conducive to improving the wearing comfort of functional fibers. © 2025 Elsevier B.V.

Based on the principle of low-carbon economy, the fabrication and design of flexible sensors with self-power and low manufacturing cost remain challenges in smart wearable electronic systems. In this study, we fabricated a self-powered piezoelectric sensor based on sustainable textiles that can be rapidly manufactured by a functional spray solution made of fluorinated polyimide (FPI) with high solubility in acetone. The as-prepared piezoelectric sensor shows excellent flexibility and enhanced intelligent sensor monitoring capabilities through incorporating barium titanate nanoparticles (BTO), while also achieving the recycling of discarded textiles. The piezoelectric sensor derived from piezoelectric spray with 20 wt% BTO concentration exhibits high piezoelectricity with output voltages reaching up to 80 V for human body detection. Furthermore, the integration of the sensor with an IoT chip-based wireless signal transmission system enables remote monitoring and emergency assistance via mobile devices, facilitating its application in smart electronic systems with great potential for application. © 2025 Elsevier Ltd

Three-dimensional braided composites (3DBC) are widely used in aerospace due to their excellent impact resistance and structural integrity. The excellent mechanical performance of 3DBC can be achieved by ensuring precise dimensions, stable structure and low-damage fabrication technology for the 3D braided preform. In this research work, we developed meso-scale and micro-scale finite element models to numerically analyze the damage and deformation behavior of braided structures during the fabrication process of 3D braided preform. The deformation and damage mechanism of fibers at different scales during 3D braiding process are first analyzed. The results show that stress always concentrates at the interlaced regions and is affected by the beating-up process. The outer yarns are more easily damaged during the braiding process. In the beating-up process, when the beater reaches the highest point, the first broken fiber is generated, and the broken fiber is located in the interlaced area. The damage caused by the beating-up motion is greater than that caused by fiber movement. The damage to the elements is mainly caused by shear stress. The greater the friction coefficient between fibers and the higher of the beating-up height, the more severe fiber deformation in the interlaced area. These results can provide valuable guidance for the fabrication of high-quality 3D braided preforms. © 2025 Elsevier Ltd

Mechanistic insights into simultaneous adsorption of contaminants in dyeing wastewater using polyurethane-based hierarchical porous adsorbents

Carbon Letters 2025年 1-17页

The adsorption of a single pollutant can no longer meet the increasingly strict requirements of environmental governance. The easy loss and secondary pollution of powdered adsorbents further hinder the industrialization of adsorption technology. Through in-situ oxidative polymerization and hydrothermal deposition, polyaniline (PANI) and magnetic Fe3O4 nanoparticles were loaded onto a polyurethane (PU) matrix to prepare polyurethane-polyaniline /Fe3O4 (PU-P/F) porous composite loading materials, aiming to simultaneously remove multiple pollutants in wastewater and solve the problem of effective solid–liquid separation at the same time. The synthesized composite material exhibited a high specific surface area (30.08 m2/g) and a hierarchical pore structure. Within a wide pH range (5–7), it showed a synchronous adsorption and removal effect on typical pollutants (ARG, Cr (VI), NO3−-N, TP, MB, NH4+-N) in printing and dyeing wastewater. Equilibrium can be reached within 0.5–2 h, following pseudo-second-order kinetics and Langmuir isotherm model, indicating mainly monolayer chemical adsorption. The continuous column adsorption regeneration test showed that for the simulated mixed wastewater, the continuous adsorption reached saturation after 660 min (53 chromatographic columns), while for the actual wastewater, the continuous column adsorption reached saturation after 535 min (43 chromatographic columns), and the efficiency remains after 8 regenerations. FT-IR and XPS confirmed the REDOX reaction between the –NH—group in polyaniline and Fe in Fe3O4, facilitating the adsorption and transformation of pollutants, while DFT calculations confirmed the strong interaction between polyaniline and anionic pollutants. This research provides ideas for solving the engineering bottleneck of adsorption technology. © The Author(s), under exclusive licence to Korean Carbon Society 2025.
