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.

High-strength, flexible, and multifunctional characteristics are highly desirable for electromagnetic interference (EMI) shielding materials in the field of electric devices. In this work, inspired by natural nacre, we fabricated large-scale, layered MXene/amarid nanofiber (ANF) nanocomposite papers blade-coating process plus sol-gel conversion step. The as-synthesized possess excellent mechanical performance, that is, exceptional tensile strength (198.80 ± 5.35 MPa), large strain (15.30 1.01%), good flexibility (folded into various models without fracture), which ascribed to synergetic interactions interconnected three-dimensional network frame hydrogen bonds between MXene ANF. More importantly, with extensive continuous conductive paths formed nanosheets present a high EMI effectiveness 13188.2 dB cm2 g-1 frequency range 8.2-12.4 GHz. interestingly, show Joule heating performance fast thermal response (<10 s) low driving voltage (≤4 V). As such, large-scale MXene/ANF considered as promising alternatives wide applications management.
