Crack-structured flexible strain sensors have attracted considerable interest in the field of flexible electronics due to their notable sensitivity and stretchability. However, crack propagation in these sensors restricts the strain range and compromises compatibility by collapsing the conductive network and degrading the interfacial adhesion. This research proposes a PVA optimization strategy based on the layer-by-layer assembly method, leading to the development of a PVA buffer layer-reinforced TPU @ MXene (MPTPU) fiber strain sensor. The incorporation of the PVA buffer layer improves interfacial adhesion and effectively alleviates stress concentration, thus broadening the effective sensing range of MPTPU. Additionally, hydrogen bonding within MPTPU improves the uniformity and adhesion of the conductive coating, enhancing the interfacial compatibility. The carefully engineered multilayer composite structure significantly boosts the sensor’s performance and stability, exhibiting a sensitivity of 12.8, 50% stretchability, a detection threshold of 0.1%, and durability exceeding 10,000 stretching cycles. Furthermore, MPTPU demonstrates effective bending sensing performance and washability, making it well-suited for integration into textiles. The strain sensor accurately detects a wide range of human motions. With these advantages, such sensors hold great promise for applications in motion detection, health management, and wearable smart devices.

Ti 3 C 2 T x is considered a candidate for high-efficiency microwave absorption materials due to its adjustable electrical conductivity , low density and high specific surface area in recent years. However, the single absorption mechanism could not meet the practical requirements as the functional microwave absorbers. Herein, 0D/1D/2D architectures of Co@C/MXene with 0D Co nanoparticles , 1D carbon nanotubes (CNTs) and 2D Ti 3 C 2 T x MXene nanosheets were rationally fabricated to enhance the microwave attenuation performance, in which Co@CNTs were in situ grown on Ti 3 C 2 T x MXene nanosheets . By changing the amount of Ti 3 C 2 T x MXene to optimize the impedance matching properties, the Co@C/M − 10 absorber exhibits excellent microwave attenuation performance with a minimum reflection loss of −50.5 dB at 5.9 GHz under a thickness of 4.0 mm. Meanwhile, the maximum effective absorption bandwidth (<−10 dB) of Co@C/M − 10 absorber can reach 5.8 GHz under 2.0 mm. The remarkable absorption performance can be ascribed to the synergistic effects of interface polarizations and magnetic loss. Moreover, the radar cross section (RCS) simulation was also performed via CST. Under the incident angle of 0°, the RCS reduction value of Co@C/M − 10 can reach 33.5 dBm 2 . This work provides a strategy for synthesizing MXene-based composite materials with tunable electromagnetic attenuation and wide absorption bandwidth performance .

Using MXene as substrate, CoOOH@MXene with different mass content of CoOOH were prepared and used to active peroxymonosulfate (PMS) for the sulfamethoxazole (SMX) degradation. The sample characterizations demonstrated the successful preparation of CoOOH@MXene. CoOOH@MXene possessed much higher BET surface area (183.82 m 2 /g) than CoOOH (85.36 m 2 /g) and MXene (6.89 m 2 /g) due to the good dispersibility of CoOOH particles on MXene. Due to its large surface area, 1.3CoOOH@MXene displayed the best catalytic performance for the degradation of SMX. With 0.2 g/L of 1.3CoOOH@MXene and 0.5 mM of PMS, 20 μM of SMX was completely eliminated in 10 min. The degradation followed pseudo-first-order kinetic model well, with rate constants of 0.33 min −1 for 1.3CoOOH@MXene and 0.054 min −1 for CoOOH. Influencing factors of initial pH, catalyst dosage, PMS concentration, SMX concentration, and co-existing anions on SMX degradation were assessed systematically. Recycling tests verified the excellent reusability and stability of the catalyst. Quenching experiments and electron paramagnetic resonance analysis substantiated that 1 O 2 played a leading role. Moreover, the intermediates were identified, and degradation pathways and activation mechanism of CoOOH@MXene for PMS were proposed. This work may highlight the application of MXene with transition metals in PMS activation.

The electromagnetic interference (EMI) shielding abilities of MXene-based conductive nanocomposites are promising for ensuring the steady operation of electronic equipment and protecting people from electromagnetic radiation. The development of comprehensive membranes that satisfy all the essential requirements of excellent EMI shielding and infrared (IR) stealth performance remains a significant issue, despite the high EMI shielding capabilities of MXene-based composite membranes . Here, we report a sandwich-structured Ti 3 C 2 T x -MXene/reduced-graphene-oxide (MrG) membrane with high conductivities and abundant interior blowholes for high-performance EMI shielding and IR stealth. Taking advantage of the continuously conductive routes and distinctive porous structures, an 18-μm-thickness MrG membrane shows a high EMI shielding efficiency (EMI SE) of 89.1 dB and a satisfactory absolute EMI SE ( S S E /t) of up to 55282.8 d B ⋅ c m 2 ⋅ g − 1 , which is the best result for MXene-based nanocomposites with similar thickness. Moreover, the MrG membrane also exhibits superior thermal camouflage ability for objects in low-temperature circumstances (like winter) and high-temperature cases (like summer), demonstrating the great promise as high-performance EMI shielding membranes for IR stealth, security protection, and counter-surveillance.

Light-driven materials have attracted great interest for their promising applications in next-generation smart devices. The incorporation of various photothermal materials into polymers has been developed for endowing composites with the capability of light harvesting and photothermal conversion, and management. However, their opaque appearance, vulnerability, and challenging processability limit their practical applications. Herein, it is successfully synthesized a series of versatile transparent films (PUMW) that combine photothermal self-healing function and mechanical strength through integrating polyurethane (PU) self-healing polymers with plasmonic enhanced MXene and W 18 O 49 hybrids (MXene@W 18 O 49 ). The resulting comprehensive film (PUMW4) maintained a visible-light transmittance of over 79% in 0.2 mm thickness, and could rapidly reach 102 °C within 5 min under light irradiation of 0.45 W cm −2 . Furthermore, it demonstrated a favorable ability for photothermal self-healing, with surface scratches disappearing in 2 min. Besides, the tensile strength of PUMW4 significantly increased from 22.7 to 30.7 MPa, in comparison with PUMW0 (pure PU). The proof of concept for an indoor thermal insulation test demonstrates that the organic glass house model covered with the film exhibited a temperature reduction of 10 °C compared to the naked model, highlighting the potential of as-prepared PUMW films in energy-saving applications for large-scale out-door buildings.

High-precision and rapid screening of harmful heavy metal contaminants like cadmium and lead ions in water bodies plays an indispensable role in ecological supervision and human health maintenance. This study fabricates V 2 CT x doped screen-printed electrodes to realize concurrent electrochemical quantification of the two metallic ions in aquatic samples. The target V 2 CT x material was obtained through selective corrosion treatment on V 2 AlC raw material. Its surface structure and internal element dispersion state were analyzed with SEM and EDS characterization techniques. Under optimized experimental parameters, square wave anodic stripping voltammetry was adopted to carry out sample measurement. Independent testing yielded LOD of 1.01 μg/L for cadmium ions and 1.91 μg/L for lead ions, respectively. When the two ions were measured concurrently, the LOD reached 2.20 and 2.39 μg/L, respectively. The V 2 CT x /SPE possessed good anti-interference property, reusability, reproducibility, and favorable preservation stability. Real water sample recovery tests (mineral water and tap water) gave recoveries between 101% and 104%, confirming its practical applicability. The V 2 CT x /SPE holds great potential for on-site rapid detection of heavy metal ions owing to its disposability, low cost, and robust performance. Graphical This work constructs a V 2 CT x MXene-modified screen-printed electrode (SPE) for square wave anodic stripping voltammetry (SWASV) synchronous quantification of aqueous cadmium (II) (Cd 2+ ) and lead (II) (Pb 2+ ). After optimizing modifier doping ratio, deposition parameters and buffer pH, the fabricated V 2 CT x /SPE achieves favorable linearity (5–50 μg L −1 ) and low limits of detection (LOD).

A novel 2D layered NbTiC solid-solution MXene was synthesized from its MAX phase via a wet chemical etching process. While ball milling the NbTiC MXene with MgH2, ultrafine bimetal NbTi nanocrystals were formed in situ with a grain size of 5 nm, which offer highly stable catalytic activity for the hydrogen storage reaction of MgH2. The MgH2-9 wt% NbTiC sample starts releasing hydrogen from 195 °C, which is 80 °C lower than that for the additive-free sample. At 250 °C, it releases approximately 5.8 wt% H2 within 30 min, and the fully dehydrogenated sample takes up 4.0 wt% H2 within 15 min even at 50 °C under 50 bar H2 pressure. DFT calculations reveal a charge transfer process from Ti atoms to Nb atoms in the NbTi cluster and a lower absolute value of the adsorption energy of H2 on NbTi. This would presumably benefit both the breakage of Mg–H bonding and the detachment of H2 from the NbTi surface, and consequently lead to good catalytic activity.

An energy storage system based on a battery-type electrode and a capacitive electrode as a hybrid supercapacitor offers a promising way to construct devices with advantages of both rechargeable batteries and carbon-based supercapacitors. NiCoAl-LDH nanosheets uniformly grow onto micron-scaled MXene sheets to form a NiCoAl-LDH/V4C3Tx heterostructure with three-dimensional interconnected porous network microstructures by a hydrothermal method. NiCoAl-LDH/V4C3Tx composite electrodes show an excellent specific capacity of 627 C g−1 at a current density of 1 A g−1 in 1 M KOH. Especially, the NiCoAl-LDH/V4C3Tx electrodes exhibit a specific capacity of 300 C g−1 even at a high current density of 20 A g−1 in 1 M KOH, showing excellent rate performance. Hybrid supercapacitors, constructed with NiCoAl-LDH/V4C3Tx as the battery-type electrode and activated carbon (AC) as the capacitive electrode, show superior energy densities of 71.7 and 45.0 W h kg−1 at power densities of 830 and 20 000 W kg−1 in 1 M KOH, respectively. The excellent capacity retention rate is 98% for the hybrid device after 10 000 cycles at 20 A g−1 in 1 M KOH. The NiCoAl-LDH/V4C3Tx heterostructures can be used as promising electrode materials for low-cost hybrid supercapacitor devices.

Highly effective decontamination of lead is a primary challenge for ecosystem protection and public health. Herein, we report a methodology of ternary cations intercalation to synthesize Ti 3 C 2 T x MXene by structural control with angstrom-level precision through mixed fluorinated salts wet etching-alkalization approach for high-efficient lead adsorption. The successive introduction of lithium, potassium, and sodium ions continuously weakens interaction forces between Ti 3 C 2 T x layers, resulting in achieving fine tailored interlayer distance from 9.8 to 15.9 Å. A high density of complexing groups are formed after ternary cations intercalation, which greatly improve the hydrophilicity of Ti 3 C 2 T x to enhance the accessibility and shorten the mass transfer and provide abundant adsorption sites to exhibit strong complexing effects with lead ions. The prepared ternary cations-intercalated Ti 3 C 2 T x nanosheets exhibited a high adsorption capacity (267.2 mg/g) toward lead ions and sharply cut down lead concentration from 10 to 0.009 mg/L, far below the drinking water standards (0.015 mg/L).

Herein, we report on a novel two-dimensional (2D) material application, which shows that an accordion-like layered Ti 3 C 2 nanomaterial (MXene) with an excellent adsorption capacity of Cr(VI) from aqueous solution was prepared by etching Al layer from Ti 3 AlC 2 phase in hydrofluoric acid (HF) solution. Ti 3 C 2 nanopowders were well characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and the physical property of as-obtained samples was studied by UV–Vis diffuse reflectance spectra (DRS). After HF treatment, Ti 3 AlC 2 not only has a phase transition from one crystal to another, but surprisingly, its microstructure is also undergoing an obvious change. Ti 3 C 2 with product of change possesses an accordion-like multilayer structure, and a relatively higher specific surface area (SSA) than untreated Ti 3 AlC 2 . Then, accordion-like Ti 3 C 2 with a high SSA provides abundant active sites for pollutant removal and functionalization. Accordion-like Ti 3 C 2 nanomaterial exhibits a stable adsorption capacity, and 1 g as-prepared accordion-like Ti 3 C 2 powders can remove about 80 mg potassium dichromate. Therefore, the results suggest that 2D MXenes are promising as an effective nanoadsorbent in heavy metal removal from the wastewater.

Two-dimensional (2D) MXene materials have significant potential applications in electrochemical energy storage. A Ti 3 C 2 T x MXene film can be used as a high-performance electrode for a flexible supercapacitor owing to its flexibility and excellent rate capability. However, Ti 3 C 2 T x is usually only used as a negative electrode material because it can be easily oxidized under positive (anodic) potential. Herein, we report a simple filtration method to fabricate a hybrid cathode by mixing a colloidal solution of 2D Ti 3 C 2 T x nanosheets and 1D MnO 2 nanobelts to form an alternating MnO 2 /Ti 3 C 2 T x stacked structure. Compared with pure Ti 3 C 2 T x , the hybrid cathode has higher electrochemical stability toward anodic oxidation. The MnO 2 /Ti 3 C 2 T x hybrid cathode delivers a high gravimetric capacitance of 315 F g −1 at 10 mV s −1 and a good rate capability of 166 F g −1 at 100 mV s −1 . The high stability of the MnO 2 /Ti 3 C 2 T x hybrid cathode is mainly attributed to the charge transfer-induced work function enlargement at the Ti 3 C 2 T x and MnO 2 heterointerface. Furthermore, a flexible asymmetric supercapacitor assembled using MnO 2 /Ti 3 C 2 T x as the cathode and alkalized Ti 3 C 2 T x as the anode delivers a high-voltage window up to 1.9 V. This work provides new insights for designing high-performance MXene-based cathode materials and devices for wearable electronics.
