The prosperous development of smart wearable electronic devices has caused extensive demand for flexible composite films with integrated electromagnetic interference (EMI) shielding and thermal management performances. However, it is still a challenge to prepare flexible composite films with desirable properties. Herein, the flexible multilayered MXene/thermoplastic polyurethane films were prepared via a simple layer-by-layer spraying technique. The multilayered films with 28.6 wt% MXene and 52-µm thickness exhibit high electrical conductivity of 1600 S/m, excellent EMI shielding effectiveness of 50.7 dB in the X-band, and outstanding specific shielding effectiveness of 7276 dB.cm2 g−1. Meanwhile, a high in-plane thermal conductivity of 6.31 W/(m.k) and low cross-plane thermal conductivity of 0.42 W/(m.k) were obtained. Besides, the obtained films exhibit excellent Joule heating performance (113 °C) with low voltage (5 V), fast response time (< 10 s), excellent heating stability, and efficient de-icing as well as potential thermal stealth performance. The multilayered MXene/TPU films were prepared by layer-by-layer spraying and exhibited excellent EMI shielding, thermal conductivity, and management performances.

Flexible, ultralight, and mechanically robust electromagnetic interference (EMI) shielding materials are urgently demanded to manage the increasing electromagnetic radiation pollution, but it remains a great challenge to simultaneously achieve ultralight yet mechanically robust properties while retaining high-efficiency EMI shielding performance. Herein, we fabricate a novel waterborne polyurethane/Ti3C2Tx MXene/nickel ferrite (WPU/MXene/NiFe2O4) hybrid aerogel by constructing a strong chemical bonding interaction between an NCO-terminated WPU prepolymer and hydroxyl functionalized MXene nanosheets. The resultant aerogels exhibit remarkable lightweight and mechanical properties, particularly high compressive stress far exceeding that of other MXene-based and WPU-based porous materials. Furthermore, synergistic effects of the oriented porous architecture and the multiphase skeleton endow the hybrid aerogels with a high X-band EMI shielding effectiveness (SE) of 64.7 dB at a low density of ∼38.2 mg/cm3. The corresponding specific SE value achieves 1694-3124 dB·cm3/g, and the SSE/d is up to 15,620 dB·cm2/g, surpassing that of most reported EMI shielding materials. Importantly, this aerogel, with excellent electromagnetic radiation protection effects and shielding reliability, is highly promising for long-term and effective EMI shielding service in various application environments.
