The renaissance of aqueous Zn ion batteries has drawn intense attention to Zn metal anode issues, including dendrites growth, dead Zn, low efficiency, and other parasitic reactions. However, against the widely used 2D Zn foil, in fact, the Zn powder anode is a more practical choice for Zn-based batteries in industrial applications, but the related solutions are rarely investigated. Herein, we focus on the Zn powder anode and disclose its unknown failure mechanism different from Zn foils. By utilization of 2D flexible conductive Ti3C2Tx MXene flakes with hexagonal close-packed lattice as electrons and ions redistributor, a stable and highly reversible Zn powder anode without dendrite growth and low polarization is constructed. Low lattice mismatch (∼10%) enables a coherent heterogeneous interface between the (0002) plane of deposited Zn and (0002) plane of the Ti3C2Tx MXene. Thus, the Zn2+ ions are induced to undergo rapid uniform nucleation and sustained reversible stripping/plating with low energy barriers via the internally bridged shuttle channels. Paired with cyano group iron hexacyanoferrate (FeHCF) cathode, the FeHCF//MXene@Zn full battery delivers superior cycle durability and rate capability, whose service life with a CE of near 100% touches 850% of bare Zn powder counterparts. The proposed Ti3C2Tx MXene redistributor strategy concerning high-speed electrons/ions channel, low-barrier heterogeneous interface, is expected to be widely applied to other alkali metal anodes.

Developing a room temperature, real-time, and efficient sensor for trimethylamine (TMA) detection remains a challenge in food safety and disease screening. Ti 3 C 2 T x , a two-dimensional material with abundant surface functional groups, is expected to form sensing materials of low operating temperature when combined with metal oxides. In this work, a series of Ti 3 C 2 T x -CuGa 2 O 4 composites were prepared using the hydrothermal method. The gas-sensing experiment found that the response values of composites were improved towards TMA at room temperature (RT). Notably, the 9.1 wt% Ti 3 C 2 T x -CuGa 2 O 4 (MCU-10) composite exhibited a response value of 33.5 towards 100 ppm TMA-a 26.8-fold enhancement compared with CuGa 2 O 4 , with a response time of 4.3 s and a recovery time of 25.7 s. Meanwhile, the MCU-10 sensor showed outstanding gas-sensing selectivity, repeatability, and long-term stability in the sensing process. The reasons of enhanced gas-sensing properties are attributed to the incorporation of abundant surface functional groups and the higher content of oxygen vacancies. Besides, a potential explanation for the abnormal sensing behavior of CuGa 2 O 4 towards reducing gases is proposed. This work not only proposes a promising sensing material for TMA gas sensors but also highlights the potence of Ti 3 C 2 T x as a sensitizing agent in the field of gas-sensing materials.

Electromagnetic shielding (EMS) fabrics have the bottlenecks of the difficulty to improve the shielding effectiveness (SE) and the lacking of absorbing properties. Finishing fabrics with Ti3C2Tx are expected to be a fast and effective way to solve these problems. In this paper, two kinds of main EMS fabrics of the stainless steel blending and copper–nickel coating are selected. Ti3AlC2 is etched using hydrochloric acid and lithium fluoride in situ to generate hydrofluoric acid to prepare multilayer Ti3C2Tx. The finishing experiments of the fabric with Ti3C2Tx impregnation are designed. The influence of multilayer Ti3C2Tx on the shielding and absorbing properties of the EMS fabric are studied. The results show that the multilayer Ti3C2Tx can be prepared and dispersed as the treatment by the proposed method. For the blended fabric, the Ti3C2Tx micro-media are absorbed or are infiltrated into the fibers in most cases. For the coated fabric, the Ti3C2Tx micro-media are on the surface of the fabric. The SE of the blended fabric in a frequency range of 6.57–18 GHz and the copper plated nickel fabric in a frequency range of 6.57–16 GHz are enhanced. At the same time, the absorbing performances of the two types of fabrics in a high frequency band above 11.97 GHz are improved. This paper can provide a new efficient and low-cost method to improve the performance of the EMS fabric and provide a reference for the design, production and evaluation of new absorbing EMS fabrics.

Ti 3 C 2 T x -reinforced epoxy (EP) coatings face challenges in simultaneously achieving multifunctional integration of anti‑corrosion and low‑wear/friction. Based on a synergistic concept combining water-repellency and sustained lubrication, a polyethyleneimine-functionalized Ti 3 C 2 T x (P-Ti 3 C 2 T x )/lithium complex grease (LCG) reinforced epoxy coating (EP@PL) featuring dual repellency-lubrication was developed via a “like‑dissolves‑like” approach. Importantly, Matthews’ method and the Full model were used to analyze coating porosity and blistering failure. Consequently, the optimized EP@P 0.12 L coating demonstrated a |Z| 0.01 Hz approximately two orders of magnitude higher than pure EP after 21 days, owing to the repellency caused by the strong interfacial tension between LCG and water that acts synergistically with P-Ti 3 C 2 T x to establish a passive barrier. Furthermore, benefiting from P-Ti 3 C 2 T x interlayer sliding and regulated oil film lubrication, the coating achieved an 89.2% reduction in friction coefficient and a 95.2% decrease in wear volume. The integrated lubrication-repellency structure offers a promising strategy for designing high-performance protective coatings.

This research reported the outstanding composite coating for anti-corrosion and anti-wear applications doped with Ti 3 C 2 Tx-(3-aminopropyltriethoxysilane, APTES)- silicon nitride (Si 3 N 4 ) fortifier, which was prepared via the bridge linking effect of the silane coupling agent APTES between Ti 3 C 2 Tx and Si 3 N 4 particles. Taking advantage of the lubricating property of Ti 3 C 2 Tx, the high hardness of Si 3 N 4 and the coupling effect of APTES, the interfacial strength between the composite filler and resin matrix was enhanced, achieving the integrated multi-functional properties of lubrication, wear resistance and corrosion prevention for the composite coating. Compared to the epoxy coating sample, adhesion strength, tensile strength and hardness showed obvious improvement, leading to excellent friction performance and anti-wear property, which were demonstrated through an ultra-low coefficient of friction (COF) of 0.046 and small wear loss of 18.6 mg (CS-17 abrasive wheel, 1000 revolutions, load of 9.8 N). Moreover, the composite coating exhibited satisfactory anti-corrosion capacity, which could be illustrated by the impedance modulus at 0.01 Hz (| Z | 0.01Hz ) remaining at 1.07 × 10 8 Ω cm 2 after the accelerated cyclic electrochemical test (−3.0 V, 30 min) of 6 cycles. The coating reported in this study made use of the advantages of two-dimensional MXene and zero-dimensional silicon nitride, and had remarkable breakthroughs in anti-corrosion and wear properties, which provided a simple and feasible idea for the optimization of coatings.

MXenes (Ti 3 C 2 T x ), a novel two-dimensional (2D) material, exhibits higher application potential in many fields due to the layered-structure and other unique characteristics. Here, the few-layer Ti 3 C 2 T x is successfully fabricated via etching and ultrasonic. The [3-(2-Aminoethyl) aminopropyl] trimethoxy silane (silane coupling agent, AEAPTES) is used to modify the as-prepared Ti 3 C 2 T x for adjusting wettability . Then, the functional Ti 3 C 2 T x (Ti 3 C 2 @Si) with different amount is introduced into waterborne polyurethane (WPU) for enhancing corrosion resistance performance. The corrosion resistance performance is evaluated by Tafel curve and electrochemical impedance spectroscopy . The results of wettability reveal that the hydrophobicity of Ti 3 C 2 @Si is significantly improved with the water contact up to 136–142°. The results of anti-corrosion measurement demonstrate that the WPU endowed with Ti 3 C 2 @Si presents the excellent corrosion resistance performance. The 0.1%Ti 3 C 2 @Si/WPU exhibits the lowest corrosion current density (2.67 × 10 −9 A/cm 2 ) and the largest corrosion resistance (3.05 × 10 6 Ω). Moreover, after 42 days’ immersion, the lowest frequency impedance of 0.1%Ti 3 C 2 @Si/WPU composite coating was 3.68 × 10 6 Ω cm 2 . This work is of great importance for potential applications of Ti 3 C 2 T x in the anti-corrosion field.

Ti 3 C 2 T x MXene-based coaxial zinc-ion hybrid fiber supercapacitors (FSCs) were fabricated with braided structure, which can be prepared continuously and present excellent flexibility and ultrastability.
A sports watch driven by the watch belts which weaved uses the obtained zinc-ion hybrid FSC and LED arrays lighted by the FSCs under embedding into textiles, demonstrating the great potential application in smart wearable textiles.
Abstract Zinc-ion hybrid fiber supercapacitors (FSCs) are promising energy storages for wearable electronics owing to their high energy density, good flexibility, and weavability. However, it is still a critical challenge to optimize the structure of the designed FSC to improve energy density and realize the continuous fabrication of super-long FSCs. Herein, we propose a braided coaxial zinc-ion hybrid FSC with several meters of Ti 3 C 2 T x MXene cathode as core electrodes, and shell zinc fiber anode was braided on the surface of the Ti 3 C 2 T x MXene fibers across the solid electrolytes. According to the simulated results using ANSYS Maxwell software, the braided structures revealed a higher capacitance compared to the spring-like structures. The resulting FSCs exhibited a high areal capacitance of 214 mF cm –2 , the energy density of 42.8 μWh cm −2 at 5 mV s −1 , and excellent cycling stability with 83.58% capacity retention after 5000 cycles. The coaxial FSC was tied several kinds of knots, proving a shape-controllable fiber energy storage. Furthermore, the knitted FSC showed superior stability and weavability, which can be woven into watch belts or embedded into textiles to power smart watches and LED arrays for a few days.

Two-dimensional titanium carbide (Ti 3 C 2 T x ) MXene has many distinctive advantages, including high conductivity, energy-storing, catalysis, etc. In particular, its accordion-like lamellar structure could provide excellent barrier properties to corrosive agents, which exhibit potential application value for anti-corrosion coatings. However, the problem that MXenes are susceptible to oxidative degradation in an aggressive environment limits its further application in the field of corrosion prevention. Herein, in our work for the first time, an effective method was developed for protecting sensitive Ti 3 C 2 T x MXene against oxidation by imidazolium salt modification (I-Ti 3 C 2 T x ), which considerably increased MXene antioxidant stability. The crystalline structure of I-Ti 3 C 2 T x remained unaltered in an aqueous solution for 30 days and kept the lamellar structure for a long period. Simultaneously, 1.0 wt% I-Ti 3 C 2 T x /EP could provide excellent anti-corrosion protection. A new synergistic mechanism for improving antioxidant stability and anti-corrosion property of I-Ti 3 C 2 T x /EP coatings was developed and clarified based on the free radical scavenging ability of imidazolium ions and the chemical characteristics of MXene.

The influence of surface charge density of nanofiltration (NF) membranes could due to enhanced electrostatic interaction through electrically assisted. In this study, the hydroxylated BaTiO 3 /Ti 3 C 2 T x (HBT)@polyvinyl alcohol (PVA) (HBTA) composite NF membranes were prepared by crosslinking HBT on the surfaces of NF membranes. The optimized HBTA-0.06 sample exhibited a water contact angle of 43.7°, zeta potential of −13.73 mV (pH = 6.5), average effective pore size of 0.319 nm, and pure water permeance of 55.1 L·m –2 ·h –1 . At an applied electric field of 3 V, the rejection rates of LiCl, NaCl, KCl, RbCl, and MgCl 2 determined for HBTA-0.06 reached 73.3%, 60.1%, 53.6%, 49.4%, and 59.8%, respectively. HBTA-0.06 has good stabilization properties that are especially advantageous for water purification , indicating good long-term filtration stability within 168 h. Furthermore, HBT doping significantly increased the charge density of the HBTA membranes and the rejection efficiency of chloride salts, both chlorine radicals (·Cl) and hydroxyl radicals (·OH) generation pathways were proposed under electrochemical assistance. Hence, electrical assistance represents a novel and effective technique for enhancing the salt rejection properties of multifunctional composite NF membranes.

A prominent topic in related fields is the search for cathode materials for aluminum-ion batteries (AIBs) with high specific capacity and outstanding cycle performance. MXenes, a two-dimensional layered material, can be used for a variety of energy storage purposes. However, their application in AIBs is hampered by poor capacity and significant self-accumulation. In this study, we employ a simple two-step process, first electrostatically adsorbing Cu2+ on MXenes and then in situ selenizing MXenes layers to produce TiSe2. The composite product F-Ti3C2Tx@Cu@TiSe2 exhibits an initial discharge specific capacity of 360.3 mAh g–1, and the capacity remains at 267.5 mAh g–1 after 100 cycles. In contrast, the directly selenized F-Ti3C2Tx@TiSe2 without Cu2+ shows a capacity of just 77.2 mAh g–1 after 100 cycles. This huge improvement is due to the fact that the electrostatic adsorption of Cu2+ on MXenes induces polarized sites with high electron density and optimizes the spatial structure of MXenes. This phenomenon effectively alleviates self-accumulation, providing a larger specific surface area and making it easier for [AlCl4]− to embed and escape. Through the X-ray photoelectron spectroscopy test and charge and discharge curves, it is found that the main capacity of the material comes from the redox reaction of [AlCl4]− and selenides in AIBs. Herein, the utilization of Cu2+ adsorbed MXenes as precursors followed by in situ selenization is innovative and also validates the great potential of Cu2+ adsorption in the field of electrochemistry.

Developing a lightweight microwave absorbing materials (MAMs) with high absorption capacity at low thickness is a perennial challenge in materials engineering. Herein, a light Ti 3 C 2 T x @Carbon/NiZn ferrite (Ti 3 C 2 T x @C/NZFO) composite is designed by synergistically incorporating dielectric–magnetic components. The inclusion of C and NZFO enhances the interfacial polarization of the substrate and optimizes its impedance matching. Additionally, the presence of NZFO also produces magnetic loss mechanisms, such as natural and exchange resonance, as well as eddy current loss. Spontaneously, Ti 3 C 2 T x @C/NZFO composite achieved a minimum reflection loss ( RL ) of –44.7 dB at 12.5 GHz and displayed an effective absorption bandwidth of 4.27 GHz (13.53–17.8 GHz) at a thin thickness of 1.3 mm ( RL < –10 dB). Besides, the Ti 3 C 2 T x @C/NZFO composite exhibits the smallest radar cross–section (RCS) value, which further corroborates its outstanding microwave absorption performance. This research offers a groundbreaking approach to designing lightweight and thin MAMs.

Polypyrrole (PPY) coating is promising for the anticorrosion of stainless steel (SS) bipolar plates (BPs) in virtue of its good conductivity and corrosion resistance . However, the poor adhesion and pore defects of pure PPY coating limit its application. In this work, a PPY/Ti 3 C 2 T x MXene composite coating was synthesized on 304SS BPs by one-step electrodeposition , which is a facile method to realize the polymerization of PPY and the doping of MXene at the same time. The PPY/MXene coating exhibits better long-term immersion stability in simulated proton exchange membrane fuel cell (PEMFC) environment than pure PPY. The enhanced corrosion resistance is mainly benefited from the enhanced barrier effect, anodic protection effect and adhesion by the introduction of MXene. Meanwhile, the introduction of MXene significantly improves the conductivity of the coating and decreases the interfacial contact resistance at 1.4 MPa from 108.16 mΩ·cm 2 to 55.24 mΩ·cm 2 .
