Abstract The morphological distribution of absorbent in composites is equally important with absorbents for the overall electromagnetic properties, but it often ignored. Herein, a comprehensive consideration including component regulation, layered arrangement structure, and gradient concentration was used to optimize impedance matching enhance loss. On microscale, incorporation magnetic Ni nanoparticles into MXene nanosheets (Ni@MXene) endows suitable intrinsic permittivity permeability. macroscale, Ni@MXene increases effective interaction area waves, inducing multiple reflection/scattering effects. this basis, according analysis absorption, reflection, transmission (A–R–T) power coefficients composites, constructed realize at low-concentration surface layer, loss middle interlayer microwave reflection high-concentration bottom layer. Consequently, composite (LG5-10–15) achieves complete absorption coverage X-band thickness 2.00–2.20 mm RL min −68.67 dB 9.85 GHz 2.05 mm, which 199.0%, 12.6%, 50.6% higher than non-layered, descending respectively. Therefore, work confirms importance structure improving performance broadens design high-performance materials.

MXene fibers with electro-conductivity and electrochemical properties have drawn growing research interest for its promising applications in wearable electronics, flexible electrodes, smart textiles. However, producing high strength keeps challenging because loose sheets are hard to compact tightly due electrostatic repulsion. Herein, ultra-compact MXene-based produced by intercalating alginate polyvinyl alcohol (PVA) layers into nanosheets chelating via metal ions (i.e., Ca2+). The hydrogen ionic bond beneficial decrease the interplanar spacing, which improves tensile strength. These result low porosity (0.2 vol%) a orientation factor of 0.877 exhibiting electrical conductivity (1006 S cm‒1). In addition, flame retardancy is enhanced without smoldering owing synergistic effect ions. Moreover, these electromagnetic interference shielding, mechanical stability, acid, alkali-resistant properties, photo-thermal can be achieved scale production. This strategy paves way continuous production functional fibers, applicable retardant fabric, wireless communication, energy harvesting,

Abstract The pressing demand for ultrathin and flexible shields to counter electromagnetic interference (EMI) has sparked interest in Ti 3 C 2 T x MXene materials due their exceptional electrical conductivity, tunable surface chemistry, layered structure. However, pure films often lack the mechanical properties required practical engineering applications, traditional reinforcement methods tend reduce conductivity. This work demonstrates an effective strategy enhance alignment densely packed structure of by regulating acidity alkalinity aqueous solutions. approach simultaneously improves strength shielding effectiveness (EMI SE). Compared with original films, modified ammonia solution (NH ·H O) via OH − show a significant improvement tensile (27.7 ± 1.9 MPa). Meanwhile, treated hydrochloric acid (HCl) H + reach even higher 39 1.5 MPa. Moreover, EMI SE values increase significantly, each reaching 66.2 58.4 dB. maximum improvements acid- alkali-treated samples are 17.9% 4%, respectively. In conclusion, simultaneous enhancement efficacy highlights potential applications materials. Graphical abstract
