The application of smart devices and artificial intelligence (AI) technologies has led to an increase in electromagnetic interference (EMI) issues. Compared with the traditional metal-based EMI shielding materials, lighter and more efficient polymer-based EMI shielding materials have a broader application prospect. In this work, we utilized electrospinning and calcination techniques to synthesize Fe 3 O 4 nanofibers and employed a layerby-layer assembly method to create a Ti 3 C 2 T x MXene/Fe 3 O 4 / carbon fiber fabric/waterborne polyurethane (Ti 3 C 2 T x MXene/ Fe 3 O 4 /CFf/WPU) composite fabric. Our findings reveal that this composite fabric possesses superior EMI shielding capabilities. Specifically, the FMC12.5−5 composite material, which contains 12.5 wt % Fe 3 O 4 and 5 wt % Ti 3 C 2 T x , demonstrates remarkable electromagnetic interference (EMI) shielding effectiveness (SE) (up to 43.6 dB) at a mere 0.4 mm thickness with a low MXene content. Meanwhile, the fabric achieves a significant anisotropic thermal conductivity of up to 0.46 W/(m K), fulfilling the in-plane thermal conductivity requirement. Additionally, the sandwich-structured composite exhibits excellent mechanical performance (Young's modulus is up to 113.5 MPa and tensile strength reaches 15.7 MPa) and is flexible enough to endure repeated bending, folding, and shaping. It maintains a reliable electrothermal conversion capability, achieving temperatures of up to 106 °C at only 2.5 V. This study has expanded the exploration of enhanced electromagnetic interference (EMI) shielding and electrothermal conversion capabilities.

“…Various amines, phenols and aldehydes originated from both biomass and petroleum can be used as raw materials to synthesize benzoxazines, offering excellent molecular design flexibility. 7 Nevertheless, shortcomings such as high curing temperature, 8 brittleness, 9 and low crosslinking density are the main obstacles that hampers the wide application of benzoxazines. 10 To overcome these drawbacks, incorporation of the additional functional groups in benzoxazine structure such as hydroxyl, amine as well as alkynyl 11 to modify structure, 12 on other hand, blending with resin containing excellent performance 13 is also a great choice like bismaleimide, 14 cyanate ester, 15 and so on.…”

Benzoxazine resins are suffering from high curing temperature, low crosslinking density, and poor toughness, which hampers their broad applications. The introduction of melamine during synthesis has been shown useful in improving these properties, but the dielectric property was deteriorated heavily. Epoxy resins show higher crosslinking density and better toughness but the thermal properties are relatively poor. Herein, the melamine based‐benzoxazine MBF was copolymerized with epoxy resin E51 in this work in order to improve the dielectric properties. The curing reactivity, polymerization mechanism and the comprehensive properties such as thermal, dielectric and mechanical properties were systematically verified. It is found that the abundant active functional groups such as amino and phenolic groups in MBF could catalyze and copolymerize with E51 and form uniform copolymers poly(MBF‐E) at various proportions. With the increasing of epoxy resins, more polar amino groups was consumed, thus the polarity and the water absorption of the copolymers decreased. Additionally, the dielectric constant decreased from 3.67 for poly(MBF) to 2.94 for poly(MBF‐60E). Meanwhile, the highest increasement of tensile strength and elongation at break value reached 130% and 70%, respectively, which may be caused by the higher crosslinking density and more flexible ether bond formed.

Ti3C2Tx materials have been developed to have application space in many fields, but there are not many works that can be compatible with infrared (IR) stealth and electromagnetic interference (EMI) shielding at the same time. To realize the multiband high EMI shielding of Ti3C2Tx materials, and to achieve stealth effect in the IR band, in this work, a composite textile is prepared by combining the Ti3C2Tx material with a carbon cloth and sputtering a very thin gold film on the surface. This composite textile can realize high EMI shielding compatible with IR stealth, in which the EMI shielding efficiency for microwave Xa‐band (8GHza‐12.4GHz) is up to 71.8 dB, for microwave Kaa‐band (26.5GHza‐40GHz) is up to 75.02 dB, and for terahertza‐band is about 30 dB. IR emissivity is as low as 0.1, and the lowest emissivity under a certain temperature reaches 0.07, which can withstand a high temperature of 500 °C. In addition, this composite textile has flexible and bendable wear. The thickness of the whole textile is about 400 µm, of which the Ti3C2Tx material thickness is only about 10 µm, the thinnest reaches 2 µm. Such a textile can be used in both people's livelihood and military applications, which has far‐reaching significance.
