Flexible multifunctional polymer-based electromagnetic interference (EMI) shielding composite films have important applications in the fields of 5G communication technology, wearable electronic devices, and artificial intelligence. Based on design a porous/multilayered structure using polyimide (PI) as matrix polymethyl methacrylate (PMMA) microspheres template, flexible (Fe3 O4 /PI)-Ti3 C2 Tx -(Fe3 /PI) with controllable pore sizes distribution Ti3 hollow are successfully prepared by sacrificial template method. Owing to structure, when size is 10 µm mass ratio PMMA/Ti3 2:1, film has most excellent EMI performance, effectiveness (EMI SE) 85 dB. It further verified finite element simulation that an effect waves. In addition, good thermal conductivity (thermal coefficient 3.49 W (m·K)-1 ) mechanical properties (tensile strength 65.3 MPa). This conductivity, demonstrated great potential for protection high-power, portable, devices.

With the rapid development of fifth-generation mobile communication technology and wearable electronic devices, electromagnetic interference radiation pollution caused by waves have attracted worldwide attention. Therefore, design highly efficient EMI shielding materials are great importance. In this work, three-dimensional graphene oxide (GO) with regular honeycomb structure (GH) is firstly constructed sacrificial template freeze-drying methods. Then, amino functionalized FeNi alloy particles (f-FeNi) loaded on GH skeleton followed in-situ reduction to prepare rGH@FeNi aerogel. Finally, rGH@FeNi/epoxy composites obtained vacuum-assisted impregnation epoxy resin. Benefitting from construction synergistic effect, a low mass fraction 2.1 wt% (rGH f-FeNi 1.2 0.9 wt%, respectively) exhibit high effectiveness (EMI SE) 46 dB, which 5.8 times that (8 dB) for rGO/FeNi/epoxy same rGO/FeNi fraction. At time, also possess excellent thermal stability (heat-resistance index temperature at maximum decomposition rate 179.1 389.0 °C mechanical properties (storage modulus 8296.2 MPa).

MXene nanomaterials stand out among 2D and have been extensively studied by researchers because of their unique layered structure, chemical diversity, outstanding physical properties. In recent years, materials rapidly opened the market for electromagnetic interference shielding technology due to excellent wave absorption (EMA) capability. However, so far, compared with development (EM) technology, there is still much room in construction MXenes application absorption. Herein, strategies, conversion mechanism, applications are reviewed. Through meticulous material design an interdisciplinary approach, expected become one smart tunable absorbers, scenarios will also broader.

Abstract Lightweight, ultra-flexible, and robust crosslinked transition metal carbide (Ti 3 C 2 MXene) coated polyimide (PI) (C-MXene@PI) porous composites are manufactured via a scalable dip-coating followed by chemical crosslinking approach. In addition to the hydrophobicity, anti-oxidation extreme-temperature stability, efficient utilization of intrinsic conductivity MXene, interfacial polarization between MXene PI, micrometer-sized pores composite foams achieved. Consequently, show satisfactory X-band electromagnetic interference (EMI) shielding effectiveness 22.5 62.5 dB at density 28.7 48.7 mg cm −3 , leading an excellent surface-specific SE 21,317 g −1 . Moreover, exhibit electrothermal performance as flexible heaters in terms prominent, rapid reproducible, stable effect low voltages superior heat more uniform distribution compared with commercial composed alloy plates. Furthermore, well attached on human body check their electromechanical sensing performance, demonstrating sensitive reliable detection motions wearable sensors. The EMI multifunctionalities, along facile easy-to-scalable manufacturing techniques, imply promising perspectives C-MXene@PI next-generation electronics, aerospace, smart devices.

The pernicious bacterial proliferation and emergence of super-resistant bacteria have already posed a great threat to public health, which drives researchers develop antibiotic-free strategies eradicate these fierce microbes. Although enormous achievements been achieved, it remains an arduous challenge realize efficient sterilization cut off the drug resistance generation. Recently, photothermal therapy (PTT) has emerged as promising solution efficiently damage integrity pathogenic based on hyperthermia beyond their tolerance. Until now, numerous agents studied for antimicrobial PTT. Among them, MXenes (a type two-dimensional transition metal carbides or nitrides) are extensively investigated one most candidates due high aspect ratio, atomic-thin thickness, excellent performance, low cytotoxicity, ultrahigh dispersibility in aqueous systems. Besides, application scenarios using antibacterial properties can be tailored via elaborated designs MXenes-based materials. In this review, synthetic approaches textural systematically presented first, then mechanisms materials documented. Subsequently, recent progress diverse fields making use performances well summarized reveal potential applications various purposes, including vitro vivo sterilization, solar water evaporation purification, flexible fabrics. Last but not least, current challenges future perspectives discussed provide theoretical guidance fabrication systems MXenes.
