Enhanced MXene performance via in-situ Ag intercalation and PST passivation • Multifunctional cotton fabric is prepared by an interfacial integration strategy. • The fabric exhibits flame retardancy, sensing, and thermal management capability. Ti 3 C 2 T x MXene-based textiles are gaining rapid attention for next-generation wearable technologies. However, drawbacks of MXene, such as susceptibility to oxidative degradation, poor adhesion to fabrics, and low flame-retardant efficiency, hinder its applications. Herein, we proposed a collaborative interfacial strategy to fabricate a durable, antioxidant Mxene-based cotton fabric (C-E-FR-cotton) that exhibited flame retardancy, sensing, and thermal management. MXene was surface-modified with Ag NPs and potassium sodium tartrate, and then firmly adhered to the fabric by covalent bonds. Flammability test results demonstrated that the C-E-FR-cotton fabric had excellent flame retardancy, with a limiting oxygen index value (LOI) of 36.8% and a reduction of 42.8% in total heat release. The fabric retained its electrical stability, exhibiting only 1.2 times its original resistance value even after 20 soaking cycles. Besides, the signal output of the fabric remained stable during 4000 s of compression-release cycles testing, demonstrating durable sensing capability. Furthermore, the C-E-FR-cotton achieved thermal regulation, including electrothermal heating (76 °C at 10 V), photothermal warming (53.5 °C under 1000 W·m −2 ), and radiative insulation equivalent to four cotton layers. This work presents a practical strategy to develop MXene-based textiles with enhanced antioxidant capacity, flame retardancy, and capabilities for sensing and personal thermal management.

The rapid development of infrared detection technology has spurred extensive interest in advanced functional materials with exceptional infrared stealth capabilities. This work fabricates a novel thermal-insulation and radiation-modulation integrated infrared stealth material, integrating polyimide (PI) aerogel fibers (endowed with thermal insulation) and MXene/tannic acid (TA) composite (featuring low emissivity and oxidation resistance), to achieve thermal camouflage for high-temperature targets. In this composite system, the abundant pores within PI aerogel fibers not only suppress gas convective heat transfer but also extend the heat conduction path along the pore walls, thus achieving efficient thermal insulation. Meanwhile, MXene's metallic-like conductivity and layered structure enable it to efficiently reflect infrared thermal radiation, minimizing radiant heat loss to the surroundings. Consequently, the composite PI/SA/TM exhibits a low thermal conductivity of 0.084 W·m −1 ·K −1 and a low emissivity of 0.17. At an ambient temperature of 200 °C, its radiant temperature is merely 40.7 °C, outperforming pure PI, TM film and commercial fabrics in terms of stealth performance. The incorporation of TA further enhances oxidation stability for PI/SA/TM, retaining excellent emissivity (0.24) even after 15 days of humid heat aging. This work provides new technical support for designing advanced functional integrated infrared stealth materials.

PSM/MXene hydrogels with reversible EMI shielding tunability of 17.95–36.30 dB over 8.2–18 GHz. • Excellent electromagnetic absorption capability and tunable EMI shielding–absorption performance. • Different temperatures detection through resistance changes induced by hydrogel network collapse and water/ion expulsion. Intelligent electromagnetic interference (EMI) shielding materials with reversible tunability hold great promise for flexible electronic and electromagnetic protection devices. In this study, heat-responsive PNIPAM/SA/HPMC/MXene hydrogels were prepared by simple in-situ polymerization and an ion crosslinking method, and their electromagnetic shielding properties can be continuously regulated. The PSM hydrogel exhibits pronounced thermoresponsive behavior near its lower critical solution temperature (LCST) and can undergo a reversible hydration-dehydration transition under external temperature stimuli. A 1.5 mm thick sample achieves a wide-range adjustable shielding performance of 17.95–36.30 dB over 8.2–18 GHz, reversibly switching between electromagnetic shielding and transmission modes. RCS simulation verifies its excellent microwave absorption performance and realizes the integration of temperature-controlled electromagnetic shielding and absorption functions. At the same time, the material has sensitive thermo-responsive resistance and stable strain-sensing characteristics, which can accurately identify ambient temperature and deformation changes. This work provides new ideas for the development of dynamically adjustable EMI shielding materials, highlighting the broad application prospects of composite hydrogels in the fields of intelligent electromagnetic protection and wearable electronics.

The MXene-based conductive hydrogels hold great promise for skin-interfaced bioelectronics but are often hindered by the restacking and oxidation of MXene nanosheets, as well as poor interfacial adhesion. To address these challenges, we propose a synergistic surface-and-interlayer engineering strategy that integrates a mussel-inspired polydopamine (PDA) coating with waterborne polyurethane (WPU) intercalation, which yields stable WPU/PDA@MXene hybrids that effectively resist oxidation and sedimentation for over 60 days. When incorporated into a polyacrylamide (PAM) network, the resulting composite hydrogel, denoted as PUDMP, exhibits remarkable mechanical properties, including high stretchability (1212%), toughness (433 kJ·m⁻ 3 ), and strong multi-substrate adhesion (188 kPa). The PUDMP hydrogel demonstrates multifunctional sensing capabilities with a negative temperature coefficient (−1.62%·°C⁻ 1 ), a wide-range strain sensitivity with gauge factors of 1.23 (0–200%) and 2.70 (200–600%), fast response/recovery (102/100 ms), and stable performance over 1000 cycles. As an epidermal electrode, PUDMP reliably captures electrophysiological signals such as ECG and electrodermal activity; as a strain sensor, it accurately tracks both subtle facial motions and large joint movements. Furthermore, when integrated as the flexible ionic/conductive electrode in a contact-separation triboelectric nanogenerator, the system achieves an open-circuit voltage of up to 112 V and a peak areal power density of 1.058 W·m⁻2, enabling energy harvesting and self-powered motion sensing. This work provides an integrated solution to the dispersion, stability, and adhesion challenges of MXene-based hydrogels, offering a practical platform for next-generation self-powered wearable bioelectronics.

An enhanced MXene-based SPR sensor combining theory and experiment is proposed. • Theory indicates that the sensitivity can be enhanced by up to 80.5% through spin-coating MXene. • Experiments show that the sensor’s sensitivity can be enhanced by up to 23.1% after spin-coating MXene. • The effects of different MXene concentrations and spin-coating cycles on the sensor are investigated. • This study lays a solid foundation for the practical development of biochemical sensors. We conduct numerical and experimental investigations on a prism-coupled surface plasmon resonance (SPR) sensor enhanced by MXene (Ti 3 C 2 T x ). The sensor is constructed in accordance with the Kretschmann configuration. The constituent layers of the proposed sensor are numerically optimized with the goal of achieving high sensitivity, detection accuracy (DA), and figure of merit (FOM). The maximum sensitivity is expected up to 3261.2 nm/RIU when Au film integrated with 9 layers of Ti 3 C 2 T x Mxene, which represents an 80.5% enhancement compared to that in the sole Au-film SPR sensor. Subsequent experimental validation is carried out, where Ti 3 C 2 T x MXene is deposited onto the surface of the Au film through a spin-coating technique. The sensor’s refractive index sensitivity, full width at half maximum (FWHM), and FOM are obtained via experimental measurements. The effects of spin-coating Ti 3 C 2 T x MXene with different concentrations and different layer numbers on the SPR sensor are investigated and discussed. The results show that the sensor achieves a sensitivity up to 2388.1 nm/RIU, indicating a maximum sensitivity enhancement of 23.1% compared to the Au-film SPR sensor. Both numerical simulations and experimental results verify that incorporating MXene into SPR sensors offers a viable strategy to improve the detection capability of SPR-based refractive index sensors.

Nano-hydroelectric generators that use abundant water resources to convert them into electricity are urgently needed to develop renewable energy supplies and alleviate the energy crisis. Inspired by the phenomenon that plants in nature rely on the bark to transport water from the roots to the branches and leaves, in this study we mimic the structure of Ginkgo bark by loading CNT-OH and Ti 3 C 2 T x MXene nanosheets onto cotton fabric using a simple in situ polymerization method to construct a nanogenerator with high capillary core wicking rate. A single CMTEPG (3 cm × 10 cm) achieves open-circuit voltage and short-circuit current of 0.36 V and 520 μA, respectively, in a simulated seawater (3.5 wt% NaCl) solution. By connecting different numbers of device units in series in a simulated seawater solution, it is possible to light small red LED bulbs and drive blue LED displays. In addition, the flexible generator shows excellent mechanical stability, and the optimized generator achieves an actual output power of 46.63 μW.

The synthesis of efficient and stable catalysts for photocatalytic reactions is still a challenge. In this study, a new photocatalyst composed of two-dimensional titanium carbide (Ti3C2Tx) and CdS quantum dots (QDs) was fabricated, in which CdS QDs were intimately anchored on the Ti3C2Tx sheet surface. Due to the specific interface characteristics of CdS QDs/Ti3C2Tx, Ti3C2Tx can considerably facilitate the generation of photogenerated charge carriers, their separation, and their transfer from CdS. As expected, the obtained CdS QDs/Ti3C2Tx exhibit outstanding photocatalytic performance for carbamazepine (CBZ) degradation. Moreover, the quenching experiments demonstrated that superoxide radicals (•O2–), H2O2, 1O2, and •OH are the reactive species involved in CBZ degradation, while •O2– made a major contribution. In addition, the sunlight-driven CdS QDs/Ti3C2Tx photocatalytic system is widely suitable for the elimination of different emerging pollutants in various water matrices, suggesting its potential practical environmental applications.

The emerging aqueous zinc-ion batteries (ZIBs) have received extensive attention and research due to their unique advantages of low cost, safety, and environmental friendliness. However, the development of appropriate cathode materials to improve battery performance remains a major challenge. Herein, a new MXene and Bi (MXene/Bi) composite material is first applied as the (de)intercalation cathode of ZIB. The dispersed MXene nanosheets in the composite materials greatly improve the conductivity and hydrophilicity of the electrode, and prevent the stacking and the volume expansion in the charge/discharge process of 2D Bi fragments. The experimental results show that composite MXene/Bi electrode has remarkable capacity and ultralong life. Next, the good kinetics and (de)intercalation energy storage mechanism of ZIB are revealed through abundant electrochemical tests and ex situ characterization. The quasi-solid-state (QSS) ZIB is also constructed, showing superior electrochemical performance, flexibility, pressure resistance, and heat resistance. Besides, the QSS ZIB can be used directly as a self-powered pressure sensor to monitor the external pressure in real time based on the response current. This study not only demonstrates that MXene/Bi is a potential cathode for ZIBs, but also offers a feasible path to explore and design the next generation of high-performance multifunctional ZIBs.

Bacterial cellulose (BC)/polypyrrole (PPy) nanofibrous composites have been extensively studied in supercapacitors owing to their large specific surface area and excellent tensile strength. However, the inferior cycling stability due to structural pulverization of PPy impedes their potential applications. Herein, nanofibrous composite membranes of MXene, PPy and oxidized BC (TOBC) were prepared for flexible supercapacitor electrodes. The C6 primary hydroxyl groups of BC nanofibers were oxidized into aldehyde or carboxyl groups. Due to the enhanced interaction of TOBC with PPy and MXene, the TOBC nanofibers were horizontally wrapped on the MXene nanosheets and PPy was homogeneously deposited on the TOBC nanofibers. The flexible solid-state supercapacitors fabricated with the MXene@TOBC@PPy (TMP) electrodes achieved an areal specific capacitance of 928.9 mF cm −2 at 0.7 mA cm −2 and a capacitance retention of 85.5% after 5000 cycles. Therefore, the TMP electrodes could be a promising electrode material for flexible supercapacitors.

In the present study, MXene-reinforced Mg matrix composites were manufactured via the electrostatic self-assembly protocol and spark plasma sintering (SPS) process to develop lightweight materials with high mechanical performance. Uniform dispersion of MXene sheets was achieved in MXene/AZ91 composites. A unique interfacial structure was confirmed in these composites, which exhibited an ultrafine MgO interlayer (grain size of ∼10 nm) coherently incorporated or intercalated into MXene layers. The unique interfacial structure contributed to robust interfacial bonding between MXene sheets and Mg matrix, resulting in a substantial mechanical performance enhancement. The yield strength of 325.3 ± 7.9 MPa and elongation of 8.8 ± 0.2% were achieved in 0.3vol% MXene/AZ91 composites, showing a significantly high strengthening efficiency of 159.1 without sacrificing ductility. Quantitatively investigation of strengthening behavior manifested that the load-transfer effect was the primary strengthening mechanism in MXene/AZ91 composites, and the simulated strength was well-matched with experimental results due to the special interfacial structure and excellent dispersion properties. This study could offer significant guidance for developing novel lightweight materials with high mechanical performance for structural applications.

Porous polymer-based Terahertz (THz) absorbers possess strong absorption with broadband, lightweight, and flexible features. Thus these are widely desired in THz electromagnetic shielding, radar-cross-section reduction, radiometer calibration, etc. However, the harsh environment of humidity, corrosiveness, and dustiness undermines the performance and service lifetime of the porous absorbers. Here, based on Ti 3 C 2 T x MXene sponge composite foam (MSF), a superhydrophobic broadband THz absorber on a large pore-size porous architecture by a joint hydrophobic strategy is realized. Results show that the apparent contact angles and roll-off angles of the modified MSF reached 159.0° and 7.6°, while maintaining an ultra-high absorption rate of 99.6% in the frequency range of 0.3–1.2 THz. Furthermore, the special Micro-Nano hierarchical structures render the absorber a strong bounce-off ability to the droplets of an aqueous solution. These water-repellent properties endow the absorber the versatility of self-cleaning and anti-corrosion, thus can be widely applied in many scenarios including THz remote sensing, communication, and security screening as well.

The development of smart hydrogel with excellent mechanical properties and photothermal conversion capability is helpful in expending its application fields. Herein, a MXene/gelatin/polyacrylamide (M/G/PAM) nanocomposite double network (NDN) hydrogel was synthesized by γ-ray radiation technology for the first time. Compared with gelatin/polyacrylamide double network hydrogel, the optimized resultant M3/G/PAM NDN hydrogel shows better mechanical properties (tensile strength of 634 ± 10 kPa, compressive strength of 3.44 ± 0.12 MPa at a compression ratio of 90%). The M3/G/PAM NDN hydrogel exhibits a faster heating rate of 30 °C min−1, stable photothermal ability, and mechanical properties even after 20 cycles of on–off 808 nm near-infrared (NIR) laser irradiation (1.0 W cm−2). Furthermore, the temperature of M3/G/PAM NDN hydrogel can be increased rapidly from 25 °C to 90 °C in 10 s and could reach 145 °C in 120 s under irradiation by focused NIR laser irradiation (56.6 W cm−2). The high mechanical property and photothermal properties of M/G/PAM hydrogel are ascribed to the formation of double network and uniform hydrogen bonding between MXene and gelatin and PAM polymers. This work paves the way for construction of photothermal hydrogels with excellent mechanical properties.Keywords:radiation synthesis;nanocomposite double-network hydrogel;mechanical properties;photothermal properties
