Although high-performance electromagnetic shields have been developed widely due to the increased electromagnetic interference (EMI) pollution, it is still desirable to construct novel EMI shields by using renewable biomass substrate and further introduce new functionalities to broaden their application scenarios. Newly 2D transition-metal carbides/nitrides (MXene) shows obvious superiority over graphene for the fabrication of multifunctional EMI shields owing to their superb electrical conductivity and tunable surface chemistry. Herein, sustainable MXene-decorated EMI shields were fabricated by depositing highly conductive Ti₃C₂T_x MXene networks onto wood-pulp fabric grid (FG) followed by hydrophobic methyltrimethoxysilane (MTMS) coating with multi-scaled roughness through a simple vacuum-filtration approach and sol-gel process. The resultant MTMS-M/FG possessed not only superior EMI-shielding effectiveness up to ~57.8–90.2 dB and outstanding waterproof feature with water contact-angle of ~132–138°, but also an impressive performance stability under cycled bending and torsion on account of their excellent mechanical flexibility and ideal structural stability. Moreover, the MTMS-M/FG showed a satisfactory low-voltage-driven Joule-heating performance with the saturated temperature of ~40–95 °C at constant 1–4 V voltage, as well as enhanced thermal stability. The above impressive functions together with simple and scalable fabrication technique would promote the possible practical applications of such unique materials.

尽管由于增加的电磁干扰（EMI）污染已广泛开发了高性能电磁屏蔽，但是仍然期望通过使用可再生生物质基质来构造新颖的EMI屏蔽并进一步引入新的功能以拓宽其应用场景。新型2D过渡金属碳化物/氮化物（MXene）由于其卓越的导电性和可调节的表面化学性质，在制造多功能EMI屏蔽罩方面显示出明显优于石墨烯的优越性。在此，通过沉积高导电性的Ti ₃ C ₂ T _x来制造可持续的MXene装饰的EMI屏蔽罩MXene网络连接到木浆织物网格（FG），然后通过简单的真空过滤方法和溶胶-凝胶工艺在疏水性甲基三甲氧基硅烷（MTMS）涂层上形成多尺度的粗糙度。最终的MTMS-M / FG不仅具有高达〜57.8–90.2 dB的卓越EMI屏蔽效果，并具有出色的防水特性（水接触角约为132–138°），而且在循环弯曲和扭转时具有出色的性能稳定性。考虑到它们出色的机械柔韧性和理想的结构稳定性。此外，MTMS-M / FG具有令人满意的低压驱动焦耳加热性能，在恒定1-4 V电压下的饱和温度约为40-95°C，并具有增强的热稳定性。
