Increasingly serious electromagnetic radiation pollution puts forward higher demands on wearable fabrics: high electromagnetic interference (EMI) shielding effectiveness. Besides, the ability for the fabrics to keep the human body warm is also important in a frigid environment. However, there have been few reports on fabrics simultaneously with the two functions so far. Here, a flexible wearable fabric with both excellent EMI shielding and passive radiation heating functions was developed through integrating silver nanowire (AgNW), ferroferric oxide (Fe₃O₄) nanoparticles, and polydimethylsiloxane (PDMS) onto a commercial fabric. The conductive AgNW networks endowed the fabric with a super-high EMI shielding property of 100.9 dB at the thickness of 450 μm – one noticeable advantage. The passive radiation heating ability was achieved by regulating the spectral selectivity of the fabric (a high solar energy absorptivity of 80.5% at 250–2500 nm, a low mid-infrared emissivity of 0.21 at 7 − 14 μm), so no electric power is needed for the fabric to heat the human body – another prominent advantage. The fabric resulted in a 20.6 °C temperature enhancement of the simulated skin under sunlight in the daytime and a 6.4 °C temperature enhancement in nighttime compared with traditional cotton fabric with the same thickness. Thus, the prepared multifunctional fabric can effectively protect the human body from electromagnetic radiation harm and injury caused by cold climate. This work holds great potential to enlarge the application scope of current EMI shielding fabrics.

日益严重的电磁辐射污染对可穿戴面料提出了更高的要求：高电磁干扰（EMI）屏蔽效能。此外，织物在寒冷环境中保持人体温暖的能力也很重要。然而，迄今为止关于织物同时具有这两种功能的报道很少。在这里，通过集成银纳米线 (AgNW)、四氧化_三铁 (Fe ₃ O ₄) 纳米粒子和聚二甲基硅氧烷 (PDMS) 到商业织物上。导电的 AgNW 网络赋予织物在 450 μm 的厚度下具有 100.9 dB 的超高 EMI 屏蔽性能——这是一个显着的优势。被动辐射加热能力是通过调节织物的光谱选择性来实现的（在 250-2500 nm 处具有 80.5% 的高太阳能吸收率，在 7 - 14 μm 处具有 0.21 的低中红外发射率），因此没有电能织物加热人体所需的另一个突出优势。与相同厚度的传统棉织物相比，该织物在白天在阳光下使模拟皮肤温度升高 20.6°C，夜间温度升高 6.4°C。因此，制备的多功能织物能有效保护人体免受寒冷气候对人体的电磁辐射伤害和伤害。这项工作对于扩大当前EMI屏蔽织物的应用范围具有很大的潜力。
