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.

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.

Two-dimensional Ti 3 C 2 T x MXene exhibits promising application prospects in the field of resistive random-access memory (RRAM) owing to its unique layered structure, abundant surface functional groups, and tunable band structure. However, the modulation of its electronic structure is critical for promoting the application of Ti 3 C 2 T x MXene in such semiconductor devices. Herein, chitosan (CS) was incorporated with Ti 3 C 2 T x MXene to construct CS-MXene composite films, which were subsequently employed as the resistive layer in the RRAM devices. The conductivity of Ti 3 C 2 T x MXene can be switched from a metallic-like state to a semiconducting state, and the resistive switching behaviors of CS-MXene hybrid films could be regulated by adjusting the mass ratio of Ti 3 C 2 T x MXene to CS. When the mass ratio of two components was 0.5, the as-fabricated Al/CS-MXene/ITO/glass device exhibited the most outstanding resistive switching (RS) performance, characterized by a lower operating voltage, a higher on/off ratio, excellent retention, and reliable endurance. Mechanistic analysis revealed that the RS behavior originates from the electron trapping/detrapping dynamics within the CS-MXene resistive layer. This work demonstrates high-performance RRAM devices based on CS-MXene composites, offering a feasible strategy for modulating the electronic structure of two-dimensional Ti 3 C 2 T x MXene.

Oxidative polymerization strengthens PPy hydrogels and optimizes evaporation enthalpy. • Ti 3 C 2 T x -PPy multilevel channels guide salt crystallization to evaporator edges. • Ti 3 C 2 T x -PPy evaporator delivers 4.63 kg m −2 h −1 , 35% higher than PPy. Solar-driven interfacial evaporation, which relies on localized photothermal conversion at the gas-liquid interface, represents an effective strategy for seawater desalination. However, continuous salt crystallization and deposition at the evaporation interface remain a critical bottleneck that limits long-term operational stability. Herein, we develop a Ti 3 C 2 T x -PPy composite hydrogel evaporator with multilevel mass-transport channels for solar seawater desalination and spatial regulation of salt crystallization. The incorporation of Ti 3 C 2 T x optimizes the internal pore network of the polypyrrole hydrogel, establishing hierarchical mass-transport pathways that promote the preferential migration of salts towards the evaporator edges, where crystallization subsequently occurs. Meanwhile, Ti 3 C 2 T x enhances the photothermal conversion capability of the system and modulates the hydrogen-bonding structure of water molecules, thereby effectively lowering the evaporation energy barrier. Under 1 sun illumination, the Ti 3 C 2 T x -PPy evaporator achieves an evaporation rate of 4.63 kg m −2 h −1 , while maintaining a clean surface and undiminished performance after 50 h of continuous operation. The evaporator also exhibits purification efficiencies exceeding 99% in hypersaline solutions, dye-contaminated wastewater and real seawater, and delivers an average daily water yield of over 25 L m −2 under natural sunlight. This work provides a promising strategy for the design of hydrogel-based solar desalination systems with high efficiency, excellent salt resistance and long-term operational stability.

A 3 vol% Ti 3 C 2 Tx@Ag addition achieves a strength–ductility synergy in Cu composites. • The Ag decoration improved MXene dispersion and interfacial bonding with Cu. • The Ti 3 C 2 Tx@Ag/Cu composites exhibited enhanced mechanical and tribological properties. Aerospace, rail transportation, and electronics require Cu-based materials with high thermal conductivity together with adequate mechanical and tribological performance. However, the relatively low strength, hardness, and wear resistance of Cu limit its use under demanding service conditions. Herein, Ti 3 C 2 T x MXene nanosheets were decorated with Ag nanoparticles, and Ti 3 C 2 T x @Ag/Cu composites were fabricated by ball milling followed by fast hot-press sintering. Ag nanoparticles were uniformly distributed on the Ti 3 C 2 T x surfaces, and the addition of Ti 3 C 2 T x @Ag progressively refined the Cu matrix grains from 5.31 μm in pure Cu to 1.24 μm at 10 vol% reinforcement. The 3 vol% Ti 3 C 2 T x @Ag/Cu composite exhibited the best strength–ductility balance, with an ultimate tensile strength of 288.5 MPa and an elongation of 41.8%, compared with 255.3 MPa and 37.6% for pure Cu, respectively. The hardness increased continuously from 48 to 116 HBW, whereas thermal conductivity showed a non-monotonic dependence on reinforcement content. Ti 3 C 2 T x @Ag produced only a modest change in the average friction coefficient but markedly improved wear resistance; the wear rate decreased from 21.24 × 10 −5 mm 3 ·(N·m) −1 for pure Cu to 6.29 × 10 −5 mm 3 ·(N·m) −1 at 10 vol%, corresponding to a 70.4% reduction. Worn-surface, wear-debris, and cross-sectional observations indicate that the improved wear resistance is mainly associated with suppressed cracking and large-scale material spalling, while friction-induced mechanical mixing and oxidation may provide an additional contribution. These results demonstrate that Ag-decorated Ti 3 C 2 T x is an effective reinforcement for jointly regulating the mechanical, thermal, and tribological behavior of Cu composites.

The practical application of Ti 3 C 2 T x MXene in supercapacitors is hindered by its tendency to spontaneously restack, which reduces accessible active sites and impedes charge transport kinetics. To address this challenge, a synergistic strategy is proposed: hydrothermally derived LaNiO 3 perovskite nanocubes are integrated into Ti 3 C 2 T x nanosheets via vacuum-assisted filtration, constructing a freestanding Ti 3 C 2 T x /LaNiO 3 composite electrode. The uniformly dispersed LaNiO 3 nanocubes act as interlayer spacers to inhibit MXene restacking and contribute capacitance, meanwhile, the conductive Ti 3 C 2 T x matrix ensures rapid electron transfer. As a result, the optimized composite exhibits a higher specific capacitance (206.8 F g -1 at 0.5 A g -1 ) than pristine Ti 3 C 2 T x , and demonstrates ultralong cycling stability (99.8% retention of the initial capacitance after 20,000 cycles at 5 A g -1 ). Furthermore, a quasi-solid-state asymmetric device (Ti 3 C 2 T x /LaNiO 3 //N-doped graphene) assembled from the composite achieves an energy density of 12.63 Wh kg -1 at a power density of 450.2 W kg -1 and maintains 88.6% of its capacitance after 10,000 cycles. Overall, this work provides a promising strategy for designing advanced MXene-based freestanding electrodes by intercalating perovskite nanocubes for next-generation energy storage systems.

The application of MXenes in organic coatings has been limited due to their tendency to agglomerate in polymer matrices, which is primarily caused by poor interfacial interactions with the polymer, and their susceptibility to oxidation under ambient conditions, resulting from the exposed Ti atoms on the surface. Here, Ti 3 C 2 T x MXene nanosheets were covalently modified with ionic liquids to prepare functionalized hybrid materials, which were subsequently incorporated as fillers into waterborne epoxy resin. The amine-functionalized ionic liquids improve the interaction between Ti 3 C 2 T x MXene and the polymer matrix, enhancing dispersion and reducing oxidation by minimizing its environmental exposure. Corrosion resistance and tribological behaviors demonstrated that the composite coating exhibited superior anti-corrosion performance, achieving a five-fold increase in the lowest frequency impedance modulus, and enhanced wear resistance, with a 64.93 % reduction in wear rate. These improvements are ascribed to the labyrinthine effect generated by the uniform dispersion of Ti 3 C 2 T x MXene nanosheets and the enhanced mechanical properties of the coating, stemming from improved interfacial compatibility with the resin. This work presents a green modification strategy for Ti 3 C 2 T x MXene, offering a viable approach to enhance its practical application in organic coatings. It also outlines potential future research directions, including further optimization of the MXene-resin interface and exploration of alternative ionic liquids for functionalization.

Ti 3 C 2 T x MXene shows potential for composite anti-corrosion composite coatings due to its excellent barrier properties and mechanical strength. However, its susceptibility to oxidative decomposition and inherent hydrophilicity limit applications in superhydrophobic coatings. To address these issues, we modified Ti 3 C 2 T x MXene nanosheets with dopamine and 1-dodecanethiol via a one-step hydrophobic treatment, producing SH/PDA-Ti 3 C 2 T x MXene. We also synthesized fluorinated prepolymers and fabricated self-healing superhydrophobic coatings with excellent photothermal and anti-corrosion properties using spray-coating. The coating exhibits outstanding anti-corrosion performance due to effective dispersion of SH/PDA- Ti 3 C 2 T x MXene, physical barrier effects, and superhydrophobic structure. SEM, EDS, and EIS analyses confirmed that the coating maintained excellent corrosion protection for Q235 substrates even after 60 days immersion in 3.5wt% NaCl solution, primarily attributed to the physical barrier of SH/PDA-Ti 3 C 2 T x MXene and superhydrophobic surface. Additionally, the coating demonstrated excellent self-healing properties: after long-term corrosive medium exposure, its impedance and contact angle rapidly recovered from 2.17 × 10 9 Ω·cm 2 and 76.9° to 9.55 × 10 10 Ω·cm 2 and 153.3° under 2.80 Sun irradiation. This study provides a novel approach for future MXene applications in metal corrosion protection through hydrophobic modification of Ti3C2Tx MXene and superhydrophobic coating construction.

Two-dimensional transition metal carbides/nitrides, typically exemplified by Ti 3 C 2 T x , featuring unique two-dimensional layered architectures, intrinsic defects, and abundant surface chemical compositions, have been recognized as highly promising novel microwave absorbing materials. Nevertheless, their intrinsic single dielectric loss mechanism significantly restricts the further improvement of microwave absorption performance. Herein, a facile solvothermal approach is proposed to anchor symmetrical pyramidal Fe 3 O 4 onto the surfaces and interlayers of Ti 3 C 2 T x and graphene nanoribbons, by which impedance matching is effectively balanced. The resulting composite, denoted as Fe 3 O 4 @Ti 3 C 2 T x /GNs, is endowed with additional loss mechanisms, thereby enhancing its microwave absorption performance. At a Ti 3 C 2 T x loading of 0.5 g/L and a thickness of 4.8 mm, the sample exhibits superior microwave absorption properties, with a minimum reflection loss of −51.97 dB achieved at 5.20 GHz, an effective absorption bandwidth of 2.72 GHz, and multi-band absorption characteristics. Notably, these findings provide valuable insights into the development of MXene-based composites with ultra-wide absorption bands and the clarification of electromagnetic wave absorption mechanisms.

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.

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.
